P267B Fault Code

B Rocker Arm Actuator Position Sensor Circuit Range/Performance Bank 2

• What does that mean?

• Solutions

The P267B fault code pertains to the Rocker Arm Actuator Position Sensor Circuit for Bank 2. This sensor plays a crucial role in regulating the variable valve timing (VVT) by monitoring the position of the rocker arm actuators. If the readings from this sensor fall outside the expected range, the engine control module (ECM) triggers this fault code, indicating a potential issue with the actuator's performance or range.

What are the symptoms of the P267B code?

Symptoms of a P267B fault code may manifest as:

• Engine misfires or poor engine performance
• Reduced fuel efficiency due to improper valve timing
• Warning lights illuminated on the dashboard, particularly the check engine light
• Unusual engine noises, such as ticking or knocking from the valve train
• Increased emissions due to abnormal combustion

What causes the P267B code?

Common causes of the P267B code include:

• Faulty rocker arm actuator
• Damaged or frayed wiring in the actuator circuit
• Poor electrical connections, such as corroded plugs or sockets
• Faulty position sensor or ECM malfunction
• Oil contamination affecting actuator performance

How to fix P267B?

To resolve the P267B fault code, consider the following steps:

• Inspect the rocker arm actuator and replace if defective
• Check and repair any damaged wiring or connectors in the actuator circuit
• Ensure proper voltage and ground at the sensor using a multimeter
• Clear the fault code and test drive the vehicle to see if the code reappears
• If issues persist, further diagnose the ECM and related components
