The automobile fault code P266E has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P266E will range between $75 and $150, depending on the repair time required.

The P266E code is related to the engine’s variable valve timing system. The Engine Control Module (ECM) commands the Rocker Arm Actuator to control the oil hydraulic circuit.

The ‘A’ Rocker Arm Actuator Position Sensor signal is monitored by the ECM.

The OBDII is set when the ‘A’ Rocker Arm Actuator Position Sensor signal is out of factory specifications.

The code indicates an intermittent or erratic circuit issue with the ‘A’ Rocker Arm Actuator Position Sensor on a specific bank. The variable valve timing system is used to improve engine performance, fuel economy, or emissions.

What are the possible causes of the P266E fault code?

If you’re experiencing the P266E fault code, your engine light may be on. This could be due to low or overfilled engine oil, incorrect engine oil type, a faulty ‘A’ Rocker Arm Actuator Sensor, an open or shorted ‘A’ Rocker Arm Actuator Sensor harness, or a poor electrical connection in the ‘A’ Rocker Arm Actuator Sensor circuit. To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or connector pins that are broken, bent, pushed out, or corroded.

How can I fix the P266E fault code?

If you’re experiencing the P266E fault code, indicated by the engine light or service engine soon warning light, it could be due to low or overfilled engine oil, incorrect oil type, or a faulty ‘A’ Rocker Arm Actuator Sensor. To fix it, check the possible causes listed above, visually inspect the wiring harness and connectors, and look for damaged components or corroded connector pins.

Is it safe to continue driving with the P266E fault code?

If you have the P266E fault code, it is not safe to continue driving your vehicle. The engine light or service engine soon warning light will be on, indicating a problem with the ‘A’ Rocker Arm Actuator Sensor.
