B Camshaft Profile Actuator A Control Circuit Low Bank 1

Where it lives

For P002B, the circuit described runs through the actuator. The description of P002B puts it on bank 1.

Check these first

• A short to ground in the bank 1 B actuator A control wire
• A failed bank 1 B camshaft profile actuator A solenoid
• Dirty or low oil at the bank 1 B phaser
• A chafed harness near the bank 1 camshaft cover
• A failed ECM driver pulling the bank 1 B circuit low

What to do next

1. Inspect the bank 1 B actuator A harness for a short to ground
2. Measure resistance across the bank 1 B actuator A solenoid
3. Check engine oil level and condition
4. Unplug the bank 1 B actuator A and watch for the low code to clear
5. Replace the bank 1 B actuator A if the solenoid is shorted
6. Clear the code and retest
