Intake Cam Position Actuator Open Circuit – Bank 2

Description:

How does a P0020 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) circuit to the computer for high and low voltages. If the voltage falls below a set limit for a specific amount of time during this test, the check engine light will come on and set this trouble code.

Possible Causes:

Open or short in the VCT circuit
Open in the Vehicle Power circuit
Open or short in the VCT solenoid valve itself
Damaged computer (PCM)

Diagnostic Help:

This check engine light code is caused by a circuit fault of the VCT system. Testing should include all related wiring circuits, the VCT solenoid and PCM itself. Please refer to out article on Automotive Circuit Testing for help with this. 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.
