B Rocker Arm Actuator Position Sensor Circuit High Bank 2
The P267D code indicates that the Engine Control Module (ECM) has detected a voltage signal from the B rocker arm actuator position sensor on Bank 2 that is higher than the expected range. This sensor monitors the position of the rocker arm actuator, which controls variable valve lift or cylinder deactivation. A high circuit condition typically points to a short to voltage, a faulty sensor, or an ECM issue. Bank 2 refers to the side of the engine opposite cylinder #1.
01. Most Common Causes
- Short to voltage in the sensor signal circuit
- Faulty B rocker arm actuator position sensor
- Damaged wiring or connector
- ECM internal failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine performance or power loss
- Rough idle or misfire
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Visually inspect the wiring and connector for damage, corrosion, or loose pins.
Step 3: Measure voltage at the sensor signal wire with key on; compare to manufacturer specs.
Step 4: Test the sensor resistance and continuity; replace if out of range.
Step 5: If wiring and sensor are good, suspect ECM and perform further diagnostics.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause engine performance issues and potential damage to the variable valve timing components.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and sensor replacement, but can be higher if wiring repairs or ECM replacement is needed.
