Description:

This error code is triggered when there is a mismatch between the desired position commanded by the ECU and the actual position of the air throttle actuator. This discrepancy can stem from mechanical restrictions, sensor failures, or electronic control issues, impacting the actuator’s ability to regulate engine air intake properly.

Reaction:

The ECU may attempt to recalibrate the actuator or limit engine performance to prevent potential damage or inefficiencies.

Recommendations:

• Inspect Actuator Mechanism: Check for any physical obstructions or mechanical wear that may prevent the actuator from moving freely.
• Test Position Sensors: Verify that the sensors responsible for monitoring actuator position are functioning correctly and providing accurate data.
• Calibrate Actuator: Use diagnostic tools to recalibrate the actuator, ensuring alignment with ECU commands.
• Replace Faulty Components: If recalibration is unsuccessful, replace faulty sensors or the actuator itself.
• Reset ECU and Verify Functionality: After repairs or recalibration, reset the ECU to ensure it properly recognizes the actuator’s new operational state. Conduct tests to confirm accurate performance under various conditions.

Note:

Regular monitoring and maintenance of the air throttle actuator are essential for optimal engine performance and reliability. Ensuring both mechanical and electronic components function correctly helps maintain efficient engine operations.
