P267E "B" Rocker Arm Actuator Position Sensor Circuit Intermittent/Erratic (Bank 2)

Here the bank 2 angle signal of lift actuator B is mostly plausible, yet it drops out for moments or jumps by amounts the motor-driven shaft could not cover in the time between two readings. The engine controller counts such events and sets P267E once they exceed its tolerance. Loose terminals, a wire cracked inside its insulation near the cylinder head, and interference from ignition or actuator wiring are the usual suspects; the fault often depends on heat or vibration. No manufacturer documents P267E publicly. CARB asks lift system inputs to be checked for signal quality, not only for fixed limits. While the reading jumps, lift control on bank 2 can hunt or be parked. Recording the signal while moving the harness helps locate the fault.

Likely causes

Symptoms

• Check engine light that may come and go
• Brief hesitation or surging
• Uneven running when lift control on bank 2 hunts

Repair estimate

Typical range across vehicles; the real cost depends on what the testing finds.
