P267A "B" Rocker Arm Actuator Position Sensor Circuit (Bank 2)

EmissionsRelevant

Drive cycleNot required

Limp modePossible

Continuously variable lift systems turn a control or eccentric shaft with an electric motor and report the shaft angle back to the engine controller. On V engines each cylinder bank has its own mechanism; Nissan's VVEL on the VQ37VHR V6 and VK50VE V8 is an example of such a two-bank layout. P267A is the unspecific circuit fault of feedback sensor B on bank 2: the signal is unusable, but the controller does not classify it as too low or too high. No manufacturer documents P267A publicly; Toyota's bulletins use the B sensor letter only for its inline Valvematic engines and code P265B. CARB requires electrical checks on every input of a lift system. Expect connector, supply or ground problems first; P267B to P267E name more specific failure patterns.

Likely causes

Loose, corroded or damaged plug at the bank 2 position sensor

Broken or chafed signal, reference or ground wire

Internal fault of position sensor B, bank 2

Fault in the engine or lift control module input

Symptoms

Check engine light on
Variable lift on bank 2 held at a fixed default
Reduced power or rough idle
