What does the camshaft adjuster solenoid do?
As part of the variable valve timing (VVT) system, the camshaft adjuster solenoid is responsible for allowing oil to adequately flow through the VVT system upon it’s engagement. The VVT system engages to deliver extra power to the vehicle when it’s traveling under added stress,…
Can a check engine light cause variable timing solenoid to fail?
This is the thing about modern cars that the ECU or engine control unit starts to warn you as soon as it finds some problem in the engine. It can, in fact, practically monitor all the individual parts of the car. So, in case of an impending variable valve timing solenoid failure, it is due to war you with check engine light.
How does the PCM control the VVT solenoids?
The PCM controls the VVT solenoids based on input from various sensors. Typically, there’s one VVT solenoid for each actuator. Some vehicles only have an actuator on the exhaust camshaft or the intake camshaft, while others have actuators on both.
Where is the variable valve timing solenoid located?
Locating the VVT Solenoid. It is located near the front of the valve cover, i.e. in the front of the engine itself. If you take the new solenoid and try to locate something that looks similar, things will be easier. You will be able to see the connector that lies at the exposed end of the variable valve timing solenoid.
What causes an exhaust camshaft position actuator code p0013?
Here are the most common causes of an exhaust camshaft position actuator solenoid valve control circuit problem or code P0013: 1 Bad VVT solenoid (aka oil control valve) 2 Problems with the VVT solenoid control circuit 3 Issues with the PCM, such as a pending software update
When does a camshaft timing over advanced code occur?
If the Engine Computer (ECM/PCM) notices that the cam timing is too far advanced and attempts to set a target to correct that incorrect angle but the Cam and Crank sensors indicate the angle didn’t correct or didn’t correct fast enough, the P0011 code is triggered on bank 1. Every engine has a bank 1.
What does the ECM / PCM do for the camshaft?
The ECM/PCM operates an oil control solenoid that supplies engine oil to each actuator (one per bank), which in turn, modifies the camshaft position angle, thereby adjusting valve timing.
What is the camshaft timing on Bank 2?
But on engines with 2 banks, (V engines) this condition on bank 2 will store a P0012 code. Remember, bank 1 is always the side where the number 1 cylinder is housed. This is true even on four cylinder inline engines. The opposite codes (Retarded Camshaft Timing) are P0012 and P0022 respectively.
