Question about 2002 Nissan Maxima

1 Answer

I have a 2002 Nissan Maxima and the check engine light has come on. One of the codes being reported is P0021. It seems to be related to a cam position sensor. Does anyone know the location of the sensor? And if the problem is just the sensor?

How to fix fault p0021 and engine failsafe program


(powertrain control module, also called an ECM). That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.
Symptoms Possible sumptoms of OBD code P0021
Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes Possible causes of OBD code P0021
A P0021 DTC trouble code may be caused by one or more of the following:
Possible Solutions This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

2003 nissan maxima p0021 bank 2 cam timing 40 degrees advanced at idle


To review - - the intake valve solenoid valve controls the flow of oil thru the control valve to adjust valve timing.
The code means the computer "sees" the valve timing as out of range and/or not controllable.
Possible causes could be a defective or stuck solenoid valve, dirty oil causing a blockage, a faulty cam sensor or faulty crank sensor.
Other than changing the oil and filter, the components would need to be checked with a scanner that can look at live data.

Fault code P0021


Hi there:P0021 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

A code P0021 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.

Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.


A P0021 DTC trouble code may be caused by one or more of the following:Incorrect camshaft timingWiring problems (harness/wiring) in intake timing control valve control solenoid systemContinuous oil flow to VCT piston chamberFailed timing valve control solenoid (stuck open)

Possible Solutions:This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.To reset the fuel pump, press the button on the switch. The switch is located immediately below the hole in the trunk side trim.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Hi there Camilo:
DTC P0011 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
A code P0011 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0011 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.
Potential Symptoms

Most likely a DTC P0011 will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes

A DTC P0011 trouble code may be caused by one or more of the following:
- Incorrect camshaft timing
- Wiring problems (harness/wiring) in intake timing control valve control solenoid system
- Continuous oil flow to VCT piston chamber
- Failed timing valve control solenoid (stuck open)

Possible Solutions:
This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis.

DTC P0462 - Fuel Level Sensor Circuit Low
This could happen happen you ran your fuel tank too low I would first fill up the tank and go to your local parts store and have them reset the code to see if it stays off .If the light comes back on the most likely reason is because the fuel level sensor needs to be replaced but other possible causes are wiring problems, fuel pump module, or cluster. You will need to barrow a special tool which is the lock wring wrench from your local parts store to remoe the fuel pump. Here are instructions from Nissan TSB (Technical Service Bulletin) to solve it; let me know if you have questions.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

If your`check engine light is on, have the codes read to find out what is causing your transmission problems, but yours seems to be a common problem, the usual symptoms of a failed speed sensor in the 00-03 maxima. Have it checked out.

U have an ignition related problem, have the system tested for the trouble code that is stored in memory any time the check engine light comes on to determine what is causing this issue. check engine lights have nothing to do with oil level or pressure, they indicate electronic control problems with the engine, trans or emission system.
