2002 Chrysler PT CruiserWe recently took our PT Cruiser in for a tune-up. Then 2 weeks later something happened to the motor mounts and the engine came loose and destroyed the axle and damaged the transmission. I’m curious if the motor mounts are even touched during a tune up. Are they removed to make more room during the tune-up? They told us that the motor mounts failed and they don’t know why and that when that happened the loose motor mounts destroyed the axle but a friend tells me that the motor mounts being loose wouldn’t damage the axle (the opposite of what the mechanic is telling us). I also feel that when they did the tune up they didn’t put things back properly and that is what created the damage to our car.


There is no reason to touch the mounts during an engine tune up. The spark plugs and ignition coils are mounted right on top of the engine and are easily accessible after removing the upper intake manifold.

Engine Motor Mount Description

The engine mounting system consists of a four-point system utilizing two load-carrying mounts and two torque struts. The load-carrying mounts are located on each frame rail. The right mount is a hydro-elastic mount and left mount is a conventional elastomeric isolator. The two torque controlling struts are attached at the front of the engine, straddling the right side load-carrying mount. The upper torque strut connects to the suspension strut tower and the lower torque strut connects to the suspension crossmember.

Engine Motor Mount Operation

The four-point engine mounting system minimizes the transmission of structure-borne engine noise to the passenger compartment. The load-carrying right and left mounts dampen and isolate vertical motion and vibration. The two struts absorbs torque reaction forces and torsional vibrations.

1999 Chrysler ConcordeI have a “crank no start” problem with my 1999 Chrysler Concorde LXI 3.2l v6. Replaced camshaft and crankshaft sensors. Replaced spark plugs. Still had the same problem. Took it to a “mechanic” who told me it was the computer(ECM). Paid another $333.00 for a new one that was phased to my car and still nothing. Injectors are good and tested. Coil pack good and tested. Found out that it would start when I unplugged CAMSHAFT connector but ran really rough. Only code I would get is a Code P0200 – Injector Circuit Malfunction. Please help. Am at wits end.


Code P0200 CHRYSLER – Fuel Injector Circuit

The P0200 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injectors. The Engine Control Module (ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0200 code when the resistance or voltage drop at the injectors is out of specifications.

Code P0200 Possible Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– Lack/Loss of Power
– The engine may be harder to start
– Engine hesitation

Code P0200 Possible causes

– Fuel Injector wiring harness is open or shorted
– Fuel injector circuit poor electrical connection
– Faulty fuel injector
– Faulty Engine Control Module (ECM)

2002 Chrysler PT CruiserCan I replace the right rear speed sensor myself?


Yes. If you have a box of tools and are mechanically inclined. One retaining bolt and one electrical plug. It will take you longer to put the car up on jack stands then it will to remove the speed sensor. Have the speed sensor shipped right to your house.

I double checked to make sure this rear wheel speed sensor will fit your 2002 Chrysler PT Cruiser. And it’s under $50. If you spend a $1 more the shipping is free.

Rear Wheel Speed Sensor Description

The Mark 20e system uses two-wire wheel speed sensors, known as active wheel speed sensors. The sensors use an electronic principle known as magnetoresistive to help increase performance and durability. The sensors convert wheel speed into a small digital signal. A wheel speed sensor is used at each wheel. The gear (tooth) type tone wheel serves as the trigger mechanism for each sensor. At each wheel of the vehicle there is one wheel speed sensor and one tone wheel.

The rear wheel speed sensors are mounted through the disc brake adapter (Left Rear Wheel Speed Sensor) (Right Rear Wheel Speed Sensor). The rear tone wheels are mounted to and rotate with the hub and bearing assemblies.

The WSS air gaps are not adjustable. The initial factory WSS air gap specification can be found in SPECIFICATIONS. Each WSS is serviced individually. The tone wheels are serviced as an assembly with the hub and bearing assemblies.

Rear Speed Sensor Operation

The CAB sends 12 volts to power an Integrated Circuit (IC) in the sensor. The IC supplies a constant 7 mA power supply to the CAB. The relationship of the tooth on the tone wheel to the permanent magnet in the sensor, signals the IC to enable a second 7 mA power supply. The output of the sensor, sent to the CAB, is a DC voltage signal with changing voltage and current levels. The ground for the IC and the current sense circuit is provided by the CAB.

When a valley of the tone wheel is aligned with the sensor, the voltage signal is approximately 0.8 volts and a constant 7 mA current is sent to the CAB. As the tone wheel rotates, the tooth shifts the magnetic field and the IC enables a second 7 mA current source. The CAB senses a voltage signal of approximately 1.6 volts and 14 mA. The CAB measures the amperage of the digital signal for each wheel. The resulting signal is interpreted by the ABS CAB as the wheel speed.

Rear Speed Sensor Removal

  1. Raise the vehicle.
  2. Remove the tire and wheel assembly from the vehicle.
  3. Disconnect the wheel speed sensor cable connector from the vehicle wiring harness (Wheel Speed Sensor Connector). Remove the clip attaching wheel speed sensor cable connector to the vehicle’s body.

  1. Disconnect the wheel speed sensor cable routing clips running along the brake tube, brake hose and axle trailing arm.
    CAUTION: When removing a wheel speed sensor from the rear disc brake adapter, do not use pliers on the sensor head. This may damage the sensor head. If the sensor has seized, use a hammer and a punch to tap the edge of the sensor head ear, rocking the sensor side-to-side until free.
  2.  Remove the bolt attaching the wheel speed sensor to the rear disc brake adapter (Wheel Speed Sensor), then carefully remove the sensor head from the rear disc brake adapter and vehicle.

2006 Chrysler PT CruiserHaving AC problems. When car is first started, the AC will only blow warm (AC compressor does not come on). I have to drive the car several miles, stop and turn it off. After several minutes I start it again and rev the engine up and down for 10 or 15 minutes. Eventually the compressor kicks on and the AC blows ice cold. I can stop the car for about an hour and when I start it again it still works. Any longer than that and I have to start the process all over again. When AC is working I can check the refrigerant charge and it’s perfect. Any help with this problem would really be appreciated. THANK YOU!!


My best guess would be the Air Conditioning Relay sticking or a failed low pressure switch(compressor cycling switch).

1994 Chrysler LHSI recently replaced the ignition unit on my car after the engine would die while warming up and never start again until the engine would completely cool down again. Since replacing the unit the engine will die a couple of times but restart and continue to run after reaching full operating temperature. Can you tell me why this is happening and how to correct it completely?


First thing to do would be to pull any engine trouble codes. This can be done without a scan tool .

The most common reason for this would be a failed Engine Coolant Temperature Sensor.

Coolant Temperature Sensor Operation

The coolant temperature sensor is a thermistor; a temperature controlled variable resistor with a range of −40°–265°F (5°–129°C) mounted in the engine coolant stream. The PCM uses the temperature input to adjust the fuel mixture slightly richer and raise the idle speed, until normal operating temperatures are reached. On all models, this sensor is also used to control the cooling (radiator) fan operation.

The PCM supplies 5.0 volts to the coolant temperature sensor. The sensor provides an input voltage to the PCM. As coolant temperature varies, the sensor resistance changes resulting in different input voltage to the PCM.

When the engine is cold, the PCM will demand slightly richer air/fuel mixtures and higher idle speeds until normal operating temperatures are reached.

The coolant temperature sensor changes resistance as the coolant temperature increases and decreases.

Coolant Temperature Sensor Testing

  • Remove the temperature sender from the engine.
  • Position the water temperature sending unit in such a way that the metal shaft (opposite end from the electrical connectors) is situated in a pot of water. Make sure that the electrical connector is not submerged and that only the tip of the sending unit’s body is in the water.
  • Heat the pot of water at a medium rate. While the water is warming, continue to measure the resistance of the terminal and the metal body of the sending unit:
    1. As the water warms up, the resistance exhibited by the ohmmeter goes down in a steady manner: the sending unit is good.
    2. As the water warms up, the resistance does not change or changes in erratic jumps: the sender is bad, replace it with a new one.
  • Install the good or new sending unit into the engine, then connect the negative battery cable.

2002 Chrysler PT Cruiser2002 Chrysler PT Cruiser has 137,000miles on it.  3 weeks ago lost power, towed it in. My mechanic said replaced fuel pump. Since then car has lost power driving twice, Hard Starting and won’ start on first try like it used to. It starts second try no codes. Mechanic said car wouldn’t act up for him and couldn’t find cause at this time. runs fine for him.


A quick test the next time you try to start the car after it has set over night. Cycle the ignition key from “OFF” to “ON” hold for 3 seconds and turn back to “OFF” repeat this four times and then try to start the car. What this does is prime the fuel lines if the the pressure is bleeding off. This is a good test for hard starting engines with fuel related problems.

Fuel Delivery Description

The front wheel drive car uses a plastic fuel tank located rear center of the vehicle.

The Fuel Delivery System consists of: the following items:

  • Electric fuel pump module
  • Fuel filter
  • Tubes/lines/hoses
  • Fuel injectors

The in-tank fuel pump module contains the fuel pump. The pump is serviced as part of the fuel pump module.

The fuel filter is not serviceable, it is mounted on the inside of the fuel tank in the fuel pump module.

Fuel Delivery Operation

The fuel system provides fuel pressure by an in-tank pump module. The PCM controls the operation of the fuel system by providing battery voltage to the fuel pump through the fuel pump relay. The PCM requires only three inputs and a good ground to operate the fuel pump relay. The three inputs are:

2006 Chrysler PT CruiserHow to replace ac/heater control panel.. vacuum lines may not be in right?


Should be only one way for the vacuum harness connector to attach. Maybe the AC Heater Control Panel Diagram below will help. It looks like the vacuum line effect the re-circulation of the Air Conditioning.

  1. Remove Control Panel Bezel
  2. Remove Center Air Duct
  3. Remove the screws that secure the AC Heater Control to the instrument panel
  4. Remove the A/C-heater control from the instrument panel to gain access to the vacuum harness, control cables and wire harness at the rear of the A/C-heater control.
    NOTE: To aid in reinstallation, note the installed position of the vacuum harness prior to removal.
  5. Disconnect the vacuum harness and wire harness from the rear of the A/C-heater control (Vacuum Harness, Control Cables and Wiring Harness).
    NOTE: To aid in reinstallation, note the installed positions of the control cables prior to removal.
  6. Disconnect the control cables from the mode and temperature control levers at the rear of the A/C-heater control.
  7. Remove the A/C-heater control from the vehicle.

AC Heater Control Panel


AC Heater Control Panel Description

Both the heater-only and heater-A/C systems use a combination of, electrical, cable, and vacuum controls. These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle.

The A/C-heater control for the heater-only or the heater-A/C system is located to the right of the instrument cluster in the instrument panel. The A/C-heater control contains rotary-type knobs. There is a blower motor speed switch, mode control switch, temperature control, and airflow control.

The A/C-heater control cannot be repaired and, if faulty or damaged, it must be replaced. The control knobs and the illumination lamps are available for service replacement.

Vacuum Description

Vehicles equipped with A/C use vacuum to operate the re-circulation door. A vacuum check valve is connected to the brake booster vacuum supply. The vacuum check valve is designed to allow vacuum to flow in only one direction through the accessory vacuum supply circuits and to stabilize the vacuum within the HVAC re-circulation circuit whenever the vehicle is accelerating or engine vacuum varies due to operating conditions.

Vacuum Operation

The use of a vacuum check valve helps to maintain the system vacuum needed to retain the selected heating-A/C mode settings. The check valve will prevent the engine from bleeding down system vacuum through the intake manifold during extended heavy engine load (low engine vacuum) operation.

The vacuum check valve cannot be repaired and, if faulty or damaged, it must be replaced.

2008 Chrysler 300I have a 2008 Chrysler 300 LX 2.7. And my oil pressure light keeps coming on after I’m braking/stopped. I changed the oil and oil filter and changed the oil pressure switch and the light still keeps coming on. And while driving the oil pressure light stays off.


The next step would be to have the oil pressure checked. Your engine requires 10 psi of oil pressure per 1,000 rpm. So you need 30 psi at 3,000 rpm and 6 psi at 600 rpm. and so on.

An actual gauge will be able to show you if everything is alright.

2005 Chrysler Town and CountryMy 2005 Chrysler Town And Country’s AC Fan Motor in the front works some times. The back one always works. I am trying to find out is it more likely that the resistor is going out or the fan motor?


The AC Fan motor should be replaced. Your air conditioning system is working as it should. When the fan motor is working the different speeds work so the resistor is fine. The resistor has no moving parts so it works on all speeds or it doesn’t. If the AC fan motor only worked on High speed then I would recommend replacing the resistor. The Fan motor has internal brushes that wear and will act as you described when going out. So replacing the AC Fan Motor should fix you right up. That is after you confirm the blower motor relay is providing power to the blower motor when it isn’t working. Otherwise you will need to replace the blower motor relay. There is a separate relay for the front motor and the rear motor. When testing make sure to set the fan speed on high. This provides direct voltage with no resistance from the resistor.
