Code P0012 - Variable Camshaft Timing Over Retarded - Bank 1

How does a P0012 code trigger the check engine light? This code will trigger the check engine light under the following condition:
* The comprehensive component monitor, referred to as the CCM, monitors the Variable Camshaft Timing (VCT) position for over-retarded cam timing. If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, the check engine light will come on and set this trouble code.

Possible Causes:
Incorrect camshaft timing
VCT solenoid valve stuck open or continuous oil flow to piston chamber
Camshaft advance mechanism binding, or faulty VCT unit

Diagnostic Help:
This check engine light code is caused by a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Possible symptoms may include rough idle, stall or hard start. Refer to manufacturer specific component tests for the VCT unit. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instructions.

Other details mentioned a P0012 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:
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. 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.

Hope helps (remember to rate and comment this).

What does the code p0012 mean


Hi Craig, hope your doing well today. The code you have P0012 means: Camshaft Timing Over-Retarded. It could be the Camshaft Position Actuator on Bank 1 or Computer and even Wiring Related. Without checking it out there is no way of knowing which is the problem. Unless you have a lot of money and just want to try the actuator, I suggest you have it checked out. Hope this helps and have an awesome day Craig!

How to fix the faulty code p0012 for 2003 mazda demino


code p0012 refers to the camshaft position (CMP) intake left front bank 1-timting over retarded/ system performance---causes---valve timing, engine mechanical fault CMP actuator wiring. To have the valve timing out it has to be the cmp actuator as the valve timing will not alter unless there is a failure in the variable actuator on the end of the cam shaft. I suggest you consult a mazda specialist mechanic to explain the workings of the cam shaft

EL VEHICULO TIENE PERDIDA DE POTENCIA Y EN EL SCANNER MUESTRA LOS CODIGO PO0011; PO0012


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 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.

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,

check your timing something could have moved out of time.your computer knows something is wrong but has no adjustment left to compensate.
