P267E Code - 'B' Rocker Arm Actuator Position Sensor Circuit Intermittent/Erratic Bank 2
Quick Answer
The diagnostic trouble code P267E indicates a problem with the 'B' rocker arm actuator position sensor circuit on Bank 2 of the engine. Common causes include Faulty Rocker Arm Actuator Position Sensor: The sensor itself may be defective and not sending accurate signals to the ECM, Damaged Wiring: The wiring harness connecting the sensor to the ECM could be damaged or have a poor connection, ECM Malfunction: A problem with the engine control module could prevent it from receiving and interpreting the sensor data correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P267E Description
The diagnostic trouble code P267E indicates a problem with the 'B' rocker arm actuator position sensor circuit on Bank 2 of the engine. The rocker arm actuator is a component that helps control the opening and closing of the intake and exhaust valves in the engine. The position sensor is responsible for monitoring the position of the rocker arm actuator and sending this information to the engine control module (ECM). When the sensor circuit is intermittent or erratic, it means that the ECM is receiving inconsistent or incorrect signals from the sensor.
Common Causes of P267E
- Faulty Rocker Arm Actuator Position Sensor: The sensor itself may be defective and not sending accurate signals to the ECM.
- Damaged Wiring: The wiring harness connecting the sensor to the ECM could be damaged or have a poor connection.
- ECM Malfunction: A problem with the engine control module could prevent it from receiving and interpreting the sensor data correctly.
- Poor Electrical Ground: Issues with the electrical ground for the sensor circuit can cause intermittent signal disruptions.
- Mechanical Failure: Internal components of the rocker arm actuator may be worn or damaged, affecting sensor readings.
Symptoms of P267E
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Engine Performance Issues: The vehicle may experience reduced power, hesitation, or rough running due to incorrect valve timing.
- Increased Emissions: A malfunctioning rocker arm actuator position sensor can lead to higher emissions output from the vehicle.
- Engine Misfires: In severe cases, the engine may misfire, causing noticeable vibrations or loss of power.
- Stalling: The engine may stall unexpectedly, especially at idle or low speeds.
How to Fix P267E
- Diagnose the Issue: Use a scan tool to retrieve the trouble code and perform a thorough inspection of the rocker arm actuator position sensor circuit.
- Test the Sensor: Check the sensor's resistance and output voltage to determine if it is functioning correctly.
- Inspect Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Check ECM: Test the engine control module to ensure it is receiving and processing the sensor data accurately. Replace if necessary.
- Clear Codes and Test Drive: Clear the trouble code from the ECM memory, reset the system, and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P267E
The typical repair costs for addressing a 'B' rocker arm actuator position sensor circuit intermittent/erratic issue can vary depending on the specific cause of the problem. In general, parts for this repair may range from $50 to $200, while labor costs can add another $100 to $300. Overall, the total repair bill could fall between $150 and $500. It is important to note that these estimates are rough averages, and actual costs may differ based on factors such as the vehicle's make and model, the location of the repair shop, and any additional repairs or parts needed. It is recommended to consult with a qualified mechanic or service center to obtain a more accurate cost estimate for this particular issue.
