B Rocker Arm Actuator Position Sensor Circuit Low Bank 2

Where it lives

For P267C, the circuit described runs through the sensor. The description of P267C puts it on bank 2.

Check these first

• A short to ground on the bank 2 B position sensor signal wire
• A failed bank 2 B rocker arm actuator position sensor
• Low voltage feeding the bank 2 B position sensor
• A corroded bank 2 B position sensor connector

What to do next

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