P267D: B Rocker Arm Actuator Position Sensor Circuit High Bank 2
The P267D code indicates that the Engine Control Module (ECM) has detected a high voltage signal from the rocker arm actuator position sensor on Bank 2. This sensor monitors the position of the rocker arm actuator, which controls variable valve lift or cylinder deactivation. A high voltage reading suggests a short to power, a faulty sensor, or wiring issues. This can lead to improper actuator operation, affecting engine performance and fuel economy.
1. Most Common Causes
- Faulty rocker arm actuator position sensor
- Short to voltage in sensor circuit
- Damaged wiring or connector
- ECM software or hardware issue
2. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine performance
- Poor fuel economy
- Rough idle or misfire
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect wiring and connectors for damage or corrosion.
Step 3: Test sensor voltage and resistance with a multimeter.
Step 4: Compare readings to manufacturer specifications.
Step 5: Replace sensor if faulty, or repair wiring as needed.
