P0011 “A” Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)

OBD-II DTC Trouble Code Description

Generic: “A” Camshaft Position – Timing Over-Advanced or System Performance (Bank 1)
Nissan: Camshaft variable timing control – Bank 1 – performance

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles, including but not limited to Toyota, VW, Honda, Chevrolet, Hyundai, Audi, Acura, etc.

A P0011 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module) or ECM (engine control module). VVT is a technology used in the engine to allow it to get greater power or efficiency at different running points.

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. This code is specific to bank 1. Bank 1 is the side of the engine that contains cylinder #1.

Potential Symptoms

Most likely a P0011 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

A P0011 DTC 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. 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.

    "Delete Error Code Permanently, Disable DTC Error Code Function for p0011 in the ECU"

    In extreme cases, we even have the option to permanently remove the specific DTC p0011 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.

    Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0011.
