P267C"B" Rocker Arm Actuator Position Sensor Circuit Low (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- With P267C the engine controller reads the bank 2 position signal of lift actuator B below its lowest valid value. A sensor of this kind is designed so that even the end stop of the shaft keeps a margin to zero volts, so a reading near ground points to an electrical cause: the signal line shorted to chassis, a lost 5 V reference, or a sensor with an internal short. No manufacturer documents P267C publicly, and no thresholds are published. CARB treats out-of-range low inputs of variable lift systems as faults that must be detected. On a V engine the controller then usually stops adjusting lift on bank 2 only. Check the reference voltage at the sensor plug before replacing parts. P267D is the high-side counterpart.
- What you may notice
- Check engine light on
- Lift on bank 2 fixed at a default position
- Noticeably weaker acceleration
- Likely causes
- LikelySignal wire shorted to ground through damaged insulation
- Possible5 V reference supply to the sensor missing
- PossibleInternal short in position sensor B, bank 2
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €80 – €1,200
