P267B concerns the bank 2 feedback of lift actuator B when the signal is electrically sound but the angle it reports does not follow the commanded value, moves too slowly, or contradicts the mechanism's known travel. Faulty learning of the end stops, a slipping sensor mount, wear in the shaft drive or a sticking actuator can all produce this picture. No manufacturer documents P267B publicly. The closest published case is Toyota's bank 1 counterpart P265B on Valvematic engines: bulletin T-SB-0098-19 starts with a learn value reset and an active test of the shaft angle, then replaces the lift controller if the fault returns. CARB expects variable lift monitors to detect missed targets and slow response. Lift on bank 2 is usually frozen.

Likely causes

End-stop learn values lost or wrong after repair or battery disconnect
Worn or sticking shaft drive of actuator B on bank 2
Position sensor drifting or loose in its mount
Lift control software needing an update

Symptoms

  • Check engine light on
  • Hesitation or reduced power
  • Uneven idle when lift is frozen on one bank
