B Rocker Arm Actuator Position Sensor Circuit High Bank 1

Where it lives

For P265D, the sensor sits on the circuit this code reports. The description of P265D puts it on bank 1.

Check these first

• A short to voltage on the bank 1 B actuator position sensor circuit
• A failed bank 1 B rocker arm actuator position sensor
• An open in the position sensor ground circuit
• A loose or corroded position sensor connector

What to do next

1. Read the bank 1 B rocker arm actuator position on a scan tool
2. Test the position sensor circuit for a short to voltage
3. Check the position sensor ground circuit
4. Inspect the position sensor connector
5. Replace the bank 1 B rocker arm actuator position sensor if the circuit tests good
6. Clear the code and retest
