Where it lives

For P265B, start at the sensor the description names. The description of P265B puts it on bank 1.

Check these first

• A bank 1 B actuator position sensor reading out of range
• A sticking bank 1 B rocker arm actuator
• High resistance in the bank 1 B position sensor 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. Compare the position sensor to commanded actuator travel
3. Test the position sensor circuit for added resistance
4. Inspect the position sensor connector
