2015 Nissan AltimaWhat would cause my check engine light and slip light to come on?


RESPONSE

The check engine light illuminates when the engines performance cycle in compromised and a specific problem is recorded.

The Slip light: An image of a car sliding tells you that either Traction Control or Vehicle Dynamic Control is active, telling you the car is close to its traction limits. If it stays on, it indicated the system is deactivated.

The only way to know would be to pull the check engine light codes. This requires a scan tool. However just about any local auto parts dealer will perform this task free of charge. Also you may want to look at this vehicle still being under warranty.

1994 Nissan Bluebirdi have had to replace the rocket gasket seals.
ive put in new spark plugs
ive put in injector cleaner.
and when car is parked up and the hood is up there is an air leak somewhere.!!!
but my car still jerks a little but when driving!!!!!!!!
its starting to frustrate me


RESPONSE

You will need to start with pulling any check engine light codes. Post the codes below in the comments. Find and repairing the vacuum leak would be a good thing as well. You may find it shows an engine misfire code. The first place to check would be an intake gasket for a vacuum leak.

2015 Nissan SentraI have a 2015 Nissan Sentra SR with 8,000 miles on it. Can anyone tell me where the transmission dipstick for the automatic transmission fluid is located? Does the car even have one? I have searched all over the internet and found nothing. It is puzzling me.


RESPONSE

It appears this is a sealed transmission and therefore does not need to be checked unless a leak has occurred. No transmission dipstick in this unit. This also means there are no service intervals for the transmission.

2012 Nissan AltimaI have a 2012 Nissan Altima coupe 2.5L. Often, randomly, the cd player will say “loading disk” when there is no disk in the player nor have I touched the radio. When that happens it’s an indication that the doors lock themselves as well which means that when I’m ready to get out of my car it won’t unlock from the inside (even if I push the button or manually unlock the lever) I have to roll down the window and unlock and open the car from the outside. It seems to happen when I hit a bump or when I’m turning either direction. Ive been trying to look online and it seems it’s an electrical problem? May I ask what might be causing it and how much it might cost? Thank you!


RESPONSE

This does seem to be a common issue but seems to have several fixes involved. It would appear there may be an issue with the door lock actuator. It may be the Switch. the actuator, the wiring harness or the connection. Removal and inspection would be necessary. Some found corrosion in the switch, some needed to replace components while others had wiring issues.

I did find a couple of TSB’s involving the door locks but none that define the problem you are describing.

1997 Nissan PathfinderMy Pathfinder will not restart after it has been running and shut off. I have replaced distributor, rotor, map, pcv. When it runs it idles good but after it gets warm and I try to restart it will not turn over.


RESPONSE

If it is the engine not turning over to start, 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. The only other thing could be a bad battery.

2005 Nissan Altima Code P0420I have a 2005 Nissan Altima 2.5l 4 cylinder and Service Engine Soon light is on and ran code. It is Code P0420 with catalyst below threshold bank 1. Now my car revs at high rpms but I am not loosing gas or mileage or performance. My question is do I replace the catylitic converter or could I just do a tune up for now because the catalytic converter is not cheap.?


RESPONSE

The most common fix for this code is to replace the catalytic converter. There is a chance that the O2 Sensor is sticking and sending a false signal, but not as common. There is no reason to replace the catalytic converter at all when it comes to drivability. The converter is installed as part of a government mandated regulation. The catalytic converter reduces emissions. You could effectively never replace the converter and not worry about the performance of your car.  Now with that said, if the vehicle has less than 75,000 miles the converter is covered under warranty and up 100,000 miles on newer vehicles. The warranty coverage is also a government mandated law.

NISSAN Code P0420 – Catalyst System Efficiency Below Threshold Bank 1

As the code description implies the P0420 code means that the vehicle’s control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0420 code is combined with other codes, try fixing the other codes first.

There is a Technical Service Bulletin for this also. it calls for reprogramming the ECM.

Nissan Code P0420 Possible causes

– Three way catalyst converter Bank 1
– Exhaust tube
– Intake air leaks
– Fuel injectors may be faulty
– Fuel injector leaks
– Spark plugs may be faulty
– Improper ignition timing
– Engine Control Module (ECM)

Nissan Infinity
I have a Nissan Infinity Qx4 and it takes time to start in the morning. What could be wrong?


RESPONSE

Thinking about the Nissan Infinity my first thought would be the fuel pressure is bleeding off at night. Try a simple test the next time it sets all night. Cycle the ignition key on and off 10 times. Each time holding the key for 5 seconds on then 5 seconds off. Then try to start it. Should start easier. The act of cycling the ignition key will prime the fuel system. If it helps you may need to have the fuel pressure regulator replaced.

2002 Nissan Quest
Just stopped running while driving, not sure if not getting spark or fuel


RESPONSE

First thing I would check would be the fuel tank to make sure you have fuel. Then, like you said, you will need to determine what you are no longer getting….spark or fuel? This Nissan quest is equipped with a 3.3L V6 engine. The 3.3L engine has a timing belt that may have broken. The engine would sound a bit different when cranking it over.

1993 Nissan Altima - Car hesitates

My car hesitates during take off. What can make it hesitate during takeoff?

———————————————————————————-
RESPONSE

Car hesitates when accelerating

There are many things that may have a hand in causing your car to hesitate. When the car hesitates it may be caused from a failing sensor. When a sensor fails the On Board Diagnostic (OBD) computer will store a code and illuminate a check engine light on the dash.
– Nissan OBD Trouble Codes for car hesitates related to transmission shifting
CODE 14 Vehicle Speed Sensor (VSS)
– Nissan OBD Trouble Codes for car hesitates related to ignition/fuel. Possible contaminated fuel or old fuel.
CODE 34 Knock (Detonation) Sensor
– Nissan Trouble Codes for car hesitates related to acceleration. Throttle electronics including wiring harness and sensors.
CODE 43 Throttle Position Sensor (TPS)
Car hesitates from Throttle body

Car hesitates when stepping on gas

Sometimes it has nothing to do with electronics and sensors. Instead look at the mechanical side. This can be a dirty throttle body. You may be able to clean the throat of the throttle body. Start with a lightly alcohol soaked rag. Make sure to get the outside of the butterfly as well. This will allow more airflow at idle. This would increase the amount of air/fuel into the engine on take off. A loose connection around the air intake and air filter locations may have occurred. A vacuum leak can cause havoc on the engines ability to control itself. Usually a higher idle accompanies this. And sometimes leaving the air conditioning on is all it takes to slow this mule down.

Car hesitates when accelerating from a stop

Your car brake system could be at fault here. If your brakes are worn they could be grabbing the rotors. A caliper may be sticking an not allowing the brakes to retract. This would cause the brakes to drag on take off. The engine would have to work harder to move. A warn hub bearing could also create drag but you would hear a grinding in most cases.
