A Rocker Arm Actuator Position Sensor Circuit High Bank 2

Where it lives

For P266D, the circuit described runs through the sensor. The description of P266D puts it on bank 2.

Check these first

• A short to voltage on the bank 2 A position sensor signal wire
• An open in the bank 2 A position sensor ground circuit
• A failed bank 2 A rocker arm actuator position sensor
• High resistance in the bank 2 A position sensor connector

What to do next

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