B Camshaft Profile Actuator A Control Circuit/Open Bank 1

Where it lives

For P002A, the actuator sits on the circuit this code reports. The description of P002A puts it on bank 1.

Check these first

• An open in the bank 1 B camshaft profile actuator A control wire
• A failed bank 1 B camshaft profile actuator A
• Corrosion at the bank 1 actuator A connector
• A failed ECM driver for the bank 1 B actuator circuit
• Low oil pressure at the bank 1 B phaser

What to do next

1. Inspect the bank 1 B actuator A connector and harness for an open
2. Measure the bank 1 B actuator A solenoid resistance
3. Check oil pressure and condition at the bank 1 B phaser
4. Verify control voltage at the actuator with the key on
5. Replace the bank 1 B actuator A if the circuit tests good
6. Clear the code and retest
