Oil flow problems to the VCT piston and phaser. What are the symptoms of the P0012 code? The ECM will turn on the Check Engine Light if the timing cannot be commanded to move.
What does the p0012 code on the PCM mean?
More specifically, the condition is set when the PCM detects that the camshaft has remained in a retarded position or that the camshaft timing on Bank 1 is above the maximum retard value. The P0012 code indicates that your car’s computer has detected a difference in the desired camshaft position angle and the actual camshaft position angle.
What is the diagnostic code for camshaft position a-timing?
Cost of diagnosing the P0012 code. P0012 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Retarded (Bank 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. What causes the P0012 code? The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.

Why does the Ford F150 have a p0012 camshaft?
This allows for a more efficient cam profile at any speed. With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift.
What does the p0012 code on an engine mean?
What the P0012 code means. P0012 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake camshaft timing for bank 1 is more retarded than what the ECM has commanded it be.
What does the ECM do on a Toyota p0012?
P0012 Toyota Description The Engine Control Module (ECM) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. As a result of the angle change, the engine timing is advance or retard.
This allows for a more efficient cam profile at any speed. With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift.
Why does my Ford Escape have a p0012?
With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012.
What does the a in the p0012 code mean?
The P0012 code indicates that your car’s computer has detected a difference in the desired camshaft position angle and the actual camshaft position angle. The “A” in the P0012 code refers to the intake camshaft in an inline or straight overhead camshaft engine.
With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012.
What does the OBD code p0012 mean?
What the P0012 code means. P0012 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake camshaft timing for bank 1 is more retarded than what the ECM has commanded it be. This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing.
Cost of diagnosing the P0012 code. P0012 is a diagnostic trouble code (DTC) for “Camshaft Position A – Timing Over-Retarded (Bank 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What happens when a p0012 DTC is set?
This code is specific to bank 1. Bank 1 is the side of the engine that contains cylinder #1. Most likely a P0012 DTC will result in one of the following: 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.
What are the symptoms of a worn out timing chain?
Listed below are 5 of the symptoms of a worn out timing chain. If you notice any of these warning signs, it’s advised you contact a local mechanic as soon as possible to diagnose the exact cause and make appropriate repairs as needed. 1. Engine misfires or runs poorly There are two ways to achieve valve timing in a combustion engine.
The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves. The P0012 code is set when the ECM detects the camshaft timing for the intake camshaft on bank 1 is more retarded than what it has been set to be. What Are The Symptoms Of Code P0012?
What causes the camshaft timing control to malfunction?
The oil needs to be the proper viscosity for the camshaft timing control to work as designed. If you use too thick of oil it can cause this system to malfunction and cause codes and running issues with the engine. Incorrect oil can cause this code and may cause multiple codes along with it. Need help with a P0012 code?
What does the code p0012 stand for in Mazda?
A code P0012 Mazda definition:the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module, also called an ECM).
What are the symptoms of the p0012 code?
What are the symptoms of the P0012 code? 1 The ECM will turn on the Check Engine Light if the timing cannot be commanded to move. 2 The engine will have a hard start condition due to the retarded timing position. 3 Fuel mileage may go down since the camshaft is not in a position to get the best possible fuel mileage.
Why does my Mazda CX-9 have bad timing?
When the timing is over retarded, it can really cause some issues with the motor. Here are some of the typical symptoms of P0012 in the Mazda CX-9: Poor Idle Quality – If the camshaft actuator fails it can be tough for the engine to find the right idle speed or idle smoothly.
A code P0012 Mazda definition:the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module, also called an ECM).
What does trouble code mean on Mazda CX 7?
The trouble code means that the camshaft timing is over retarded. The PCM looks at the camshaft sensor signal and measures it against the crankshaft sensor signal to determine exactly how the cam and crank are synchronized.
More specifically, the condition is set when the PCM detects that the camshaft has remained in a retarded position or that the camshaft timing on Bank 1 is above the maximum retard value. The P0012 code indicates that your car’s computer has detected a difference in the desired camshaft position angle and the actual camshaft position angle.
What is the DTC code on a Toyota p0012?
That consists of a few different components but the P0012 Toyota DTC specifically definition:the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. The “A” camshaft is either the intake, left, or front camshaft.
