P265D: B Rocker Arm Actuator Position Sensor Circuit High Bank 1
Standardized SAE J2012 code · P26xx — Computer and output circuits
What does P265D mean?
The position sensor signal for actuator B on bank 1 is above the upper diagnostic threshold. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Open sensor element
- Medium Signal wire shorted to the 5 V reference
- Low Connector pins corroded - high contact resistance
