I got diagnostic code p0021.

Question

I have Nissan Murano 2009. I got diagnostic code p0021. What it can be? The ignition plugs are not so good.

Answer 1

Hi there,

The code is for the variable timing control solenoid on bank 2. This code can be caused by several things. Oil level and condition, a bad cam position sensor. The timing control solenoid and the timing chain. These all will need to be checked to determine the cause.
