P265E: B Rocker Arm Actuator Position Sensor Circuit Intermittent/Erratic Bank 1
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P265E mean?
The position sensor signal for actuator B on bank 1 jumps or drops out intermittently. Usually a loose connector or a chafed wire.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Sensor connector not fully seated
- Medium Harness chafed against valve cover
- Low Connector with intermittent contact under vibration
