P265D"B" Rocker Arm Actuator Position Sensor Circuit High (Bank 1)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P265D stands for a feedback signal from position sensor B, bank 1, that sits above its valid ceiling. A reading pinned near the supply voltage usually means the signal is no longer pulled toward a real value: the sensor ground has opened, the signal wire touches a reference or battery line, or moisture has bridged pins in the plug. Because such a value would describe a position the actuator cannot reach, the controller discards it and holds lift at a default. CARB requires out-of-range high detection for every input of a variable lift system. No manufacturer publishes P265D; Toyota's public Valvematic bulletins mention only P265B for this sensor. Check ground continuity first, then the connector. Low side: P265C; intermittent faults: P265E.
- What you may notice
- MIL on
- Lift frozen at default, weaker acceleration
- Likely causes
- LikelyOpen ground wire of position sensor B
- PossibleSignal wire shorted to the 5 V reference or battery voltage
- RareMoisture bridging pins in the sensor plug
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
