P267D "B" Rocker Arm Actuator Position Sensor Circuit High (Bank 2)

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

P267D is stored when the angle feedback of lift actuator B on bank 2 rises above its upper valid limit. Typical causes are an open sensor ground, which lets the signal float toward the reference, a signal conductor touching a supply line, or water bridging contacts in the connector. Systems such as BMW's Valvetronic, where an electric motor swings an eccentric shaft through a fixed arc, never place the sensor at the supply rail in normal operation, so such a value is rejected. No manufacturer documents P267D publicly; detection follows from CARB's input checks for variable lift. The controller holds bank 2 at a safe setting. Measure ground continuity first. Low-side partner: P267C; dropouts: P267E.

Likely causes

Open or high-resistance ground of the position sensor
Signal wire shorted to reference or battery voltage
Moisture or corrosion bridging pins in the sensor plug
Defective position sensor B, bank 2

Symptoms

  • Check engine light on
  • Reduced power with lift fixed on bank 2
  • Slightly higher fuel consumption
