P0020 - Intake Camshaft Position Actuator Circuit / Open (Bank 2)

About Trouble Code P0020

When the engine’s computer has decided that the bank 2 intake camshaft oil control valve has a short circuit, it will trigger trouble code P0020. It only occurs during one drive cycle.

Symptoms of Trouble Code P0020

As with all trouble code’s, when the engine’s computer realizes there is a problem, the check engine light will illuminate. If the oil control valve is open or short the engine may have a hard start and decreased fuel economy. While driving you may feel a rough run or stalling depending on if the circuit is open or shorted.

Causes of Trouble Code P0020

The engine’s computer may be trying to command the oil control valve to less than an 80% duty cycle but reads output of 100%, or it may command up to 70% and reads an output of less than 3%, causing trouble code P0020 to appear. If the oil control valve or wiring to the bank 1 exhaust camshaft has a short or if there is an open circuit this code will also appear.

How to Fix Trouble Code P0020

Start by clearing the code, taking the vehicle for a drive, and validating that the code resurfaces. Once validated, check over the wiring to the intake camshaft oil control valve for bank 2, replacing if there are signs of damage or corrosion. You may have to replace the camshaft oil control valve for bank 2 in the intake camshaft. If after additional testing, you may need to look into replacing the engine’s computer itself.
