P267E: Bank 2 Rocker Arm Actuator Position Sensor Intermittent/Erratic
The P267E code indicates that the Engine Control Module (ECM) has detected an intermittent or erratic signal from the Bank 2 rocker arm actuator position sensor. This sensor monitors the position of the rocker arm actuator, which controls variable valve lift or cylinder deactivation systems. An intermittent signal can be caused by wiring issues, connector corrosion, a faulty sensor, or internal engine mechanical problems. This code is often accompanied by drivability issues and may trigger the check engine light.
1. Most Common Causes
- Faulty rocker arm actuator position sensor
- Damaged or corroded wiring/connectors
- Intermittent electrical connection
- Engine mechanical issue (e.g., low oil pressure, worn rocker arm)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or misfire
- Reduced engine performance or power loss
- Poor fuel economy
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the Bank 2 rocker arm actuator sensor wiring and connector for damage or corrosion.
Step 3: Test the sensor signal with a multimeter or oscilloscope while wiggling the harness to reproduce the intermittent fault.
Step 4: Check for related mechanical issues like low oil pressure or worn rocker arm components.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the issue can cause engine performance problems and potential damage to the variable valve lift system.
How much does it cost to fix?▼
Diagnosis typically costs $50-$150. Sensor replacement parts range from $50-$200, plus labor. Total cost can be $150-$400 depending on the vehicle.
