2014 Hyundai ElantraIs there anything that would cause a battery 2 go totally dead, can’t get a charge.


Number one cause would be leaving a light on. This can be done by not shutting the trunk,glove box or door securely. Could have left a charge cord plugged in too long. But most likely there is an internal short in the factory battery. I have found that factory batteries do not tend to last as long as they should. Once the battery goes completely flat it takes a lot of encouragement from a low amperage battery charger. The low amperage charger will need to be left on for a couple of days or longer. Trying to jump start the car is not a good option on a completely flat battery. I recommend replacing the battery and then having the alternator tested to be on the safe side. Of course checking to make sure anything left plugged in should be checked so this doesn’t happen again.

2001 Hyundai TiburonI had a tune up completed on the car today and the car is not getting gas. My mechanic thinks it is the Hyundai fuel pump because no feedback from the fuel pump. Exactly where is the fuel pump located on this car. The mechanic said he thinks it is in the gas tank.


The Hyundai fuel pump is located inside the fuel tank yet still easy to get to. It is accessed easily because all you need to do is remove the rear seat cushion.

Hyundai Fuel Pump 2001 Tiburon Removal


  1. Remove the rear seat cushion.
  2. To reduce the internal pressure of the fuel lines and hoses, first start the engine and then disconnect the electrical fuel pump connector. Hyundai Fuel Pump location 2001 TiburonBe sure to reduce the fuel pressure before disconnecting the fuel main pipe and hose otherwise fuel will spill out.
  3. Disconnect the battery cable from the negative terminal of the battery.
  4. Remove the high pressure hose and fuel return hose.
  5. Finally the fuel pump assembly may now be removed.

2008 Hyundai EntourageI accidentally filled up with flex fuel. Should I be worried, what should I do?


It can damage fuel lines, injectors, hoses and other rubberized parts, and cause engine startup problems, rough running and other ills. Flex fuel engines are modified to prevent those problems. The E85 Ethanol based fuel should be removed from the fuel tank ASAP if you tank was below 1/4 tank when you filled up.

If you only added a few gallons, I wouldn’t worry to much. Just drive it as normal and once it gets down to 3/4 of a tank, top it back off. Repeat for a week or so. This should be enough to help prevent any damage.

2005 Hyundai TusconI went to auto zone for a scan on my 2005 Hyundai Tuscon 2wd with automatic transmission. The car was skipping and error code p0734 and code p0700 came up. I was told to replace speed sensors and change fluid does this sound right?


Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

HYUNDAI Code P0734 – Fourth Gear Incorrect Ratio

P0734 is detected when A/T cannot be shifted to the 4th gear position even if electrical circuit is good.

Code P0734 Possible symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– Incorrect transmission shifting

P0734 Hyundai Description

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor

B: Engine speed signal from Engine Control Module (ECM)

C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

HYUNDAI Code P0700 – TCU Request For MIL On

Since the P0700 is just and informative code, check the TCM for more codes to resolve the problem.

Code P0700 Possible symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– Driveability problems
– Transmission shifting problems

Possible causes

– Shorted or open circuit within Transmission Control Module (TCM)
– Faulty Transmission Control Module (TCM)

 Hyundai Code P0700 Description

The Transmission Control Module (TCM) monitors the malfunction of sensors and actuators relating to transmission control. When the TCM detects a malfunction with the control, a signal is send to the Engine Control Module (ECM) to trigger the Engine Light or Service Engine Soon light. The ECM stores the P0700 code and it means the TCM detected a malfunction with the transmission controls.

2008 Hyundai Sante FeI have codes for cyl 1, 3, and 5 misfires, along with codes for injectors circuit 1, 3, and 5 voltage low. Besides a harness what would cause these all at the same time? I can clear the codes and they won’t come back unless the vehicle is driven for 20 plus miles.



Hyundai Code P0300 – Random/Multiple Cylinder Misfire Detected

Hyundai Code P0300 Possible causes

– Faulty spark plug (s)
– Faulty ignition coil (s)
– Clogged or faulty fuel injector (s)
– Intake air leak
– Fuel injectors harness is open or shorted
– Fuel Injectors circuit poor electrical connection
– Ignition coils harness is open or shorted
– Ignition coils circuit poor electrical connection
– Insufficient cylinders compression
– Incorrect fuel pressure

The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem, see “Possible Causes”.

There is a factory technical service bulletin for the following Hyundai models:

Accent (MC)
2003-2006 SULEV Elantra (XD)
2004-2008 Tiburon 2.0L (GK)
Tucson 2.0L (JM)
Elantra (HD)
Elantra Touring (FD)
Genesis Coupe (BK)
Sonata (NF)
Santa Fe
Sonata (NF)
Santa Fe (CM)
Azera (TG)
Veracruz (EN)
Entourage (EP),
Genesis Coupe (BK)
Genesis Sedan (BH)Genesis Sedan (BH)

The bulletin provides information on how to inspect and diagnose problems related to the Oil Control Valve (OCV) used in Constant Variable Valve Timing (CVVT), if at any time the OCV is suspected as the caused of rough idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire-related trouble codes.

P0203 HYUNDAI – Injector Circuit Open – Cylinder 3

Possible causes
– Faulty fuel injector 3
– Fuel Injector 3 harness is open or shorted
– Fuel injector 3 circuit poor electrical connection
The P0203 is set if the Engine Control Module (ECM) is detects a low or high voltage drop or resistance at the injector 3.

Engine Control Module (ECM) checks the injectors circuit resistance and monitors the voltage drop during normal operation. The ECM will trigger the P0203 code when the resistance or voltage drop at the injector 3 is out of specifications.

2006 Hyundai TiburonHi, I need some help. Just over a week ago I bought a used 2006 Tiburon A/T with 116,000km on it. It looks great and drove fine until yesterday, when suddenly it refused to shift into second gear after stopping at a traffic light. I was on a busy road and couldn’t really push the transmission to see if it would eventually shift, but the rpm definitely went to about 4,000 without shifting. It happened after shifting from N into D, and I think I took my foot off the brake a little to early – I felt the car jolting a bit forward when I shifted into D. After parking and restarting the car, it worked fine. Has anyone had a similar problem? Does this mean the transmission is toast, or is it a sensor issue, or any other ideas what it could be? The transmission fluid seems fine and I can see no leaks under the car.


You stated “After parking and restarting the car, it worked fine.” With that said, It may have just been a glitch.

As for taking your foot off the brake too early shifting from neutral to drive… This is commonly referred to as a “Neutral Drop”. This is considered Hot Rodding and is performed to try and get the tires to spin. It will cause internal damage to the transmission if repeated. Sometimes it only takes one time to cause damage.

If the transmission shifts OK now, try to refrain from placing the transmission in neutral. It may tempt you to do it again. Once the car is placed in drive there really isn’t a reason to touch the shifter until you need to place it in Park.

If the transmission no longer shifts correctly, you have damaged it internally.

2001 Hyundai SonataI am working on my 2001 Hyundai Sonata 2.4l. I have been going over the wiring diagrams for the CMP sensor and it shows the number 3 wire going to the center of the sensor but is listed as number 3 and is a pink wire. Number one is showing as the top position and is the ground wire blk. And finally the number 2 wire is showing on the diagram as being in the bottom position on the sensor. But like I said it is listed as the number 2 wire and is blk with a blue strip. So I am confused. Does the pink wire go in the middle or at the bottom of the sensor?


cmp sensor connector diagram hyundai

Most wiring diagrams can be a bit confusing to read at times. This diagram is showing you what color wires they are and what number the wire is. The connector diagram tells you where the wire goes in correlation to the CMP Sensor. The connection goes as ordered in the above diagram. (thank you for providing the wiring diagrams).

  • Number one position in the connector is the ground wire
  • Number two position is the control wire connecting to the E/TCM(Engine /Transmission Control module)
  • Number three position is the pink wire connecting from the 15 amp EGR Fuse. This wire will be hot in ON & START position.

CMP Sensor

A Camshaft Position (CMP) sensor consists of a permanent magnet, yoke and coil. The CMP sensor is positioned next to the cam gear. As each cam gear tooth passes the sensor magnetic pick-up an AC voltage pulse is induced in the coil. The PCM counts the number of pulses to determine the camshaft speed. And the number of pulses counted in one second is the signal frequency.

The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start.

2003 Hyundai Sante FeRandomly will not start. The battery is good, and the ground cable is good, and I said it just is random and then any where from a few hours to day it will start.


If it is the engine not turning over to start you are mentioning, the problem would be the starter assembly. Replace the starter and it should be fine once more. The internal brushes become worn and no longer make good contact.

2004 Hyundai XG350What is the location of EGR valve and location of down stream o2 sensors.


The EGR valve is located on top of the engine. The downstream O2 Sensors are located after the catalytic converter.


The Exhaust Gas Recirculation (EGR) system lowers the nitrogen oxide (NOx) emission level. When the air/fuel mixture combustion temperature is high, a large quantity of nitrogen oxides (NOx) is generated in the combustion chamber. Therefore, this system recirculates part of emission gas from the exhaust port of the cylinder head to the combustion chamber through the intake manifold to decrease the air/fuel mixture combustion temperature, resulting in reduction of NOx.
The EGR flow rate is controlled by the EGR valve so as not to dffect the driveability.
When the engine coolant temperature is low, the engine is at idle or when a wide open throttle operation is performed, the EGR valve is kept closed, allowing no EGR.
In normal vehicle operation, after the engine has warmed up, the EGR valve is opened to carry out EGR.
In addition, the engine control module monitors the EGR system and illuminates the check engine/malfunction indicator lamp to let the driver know that there is a malfunction.
