Description:

This error occurs when there is a discrepancy between the desired and actual positions of the air throttle actuator, indicating a potential issue with the actuator’s positioning system or feedback sensors.

Reaction:

The control system might attempt to recalibrate the actuator or limit engine functionality to prevent inefficient combustion or potential damage due to incorrect air intake.

Recommendations:

• Inspect Air Throttle Actuator and Sensors: Check the actuator for mechanical freedom of movement and inspect position sensors for accuracy and functionality.
• Calibrate or Reset Actuator: Perform a recalibration of the actuator or reset it to attempt to correct the positioning mismatch.
• Test System Operation: After recalibration, test the throttle system under various operating conditions to ensure it meets the control parameters set by the ECU.
• Replace Faulty Components if Necessary: If recalibration does not resolve the issue, replace faulty sensors or the actuator itself.

Note:

Ensuring the correct operation of the air throttle actuator is essential for maintaining optimal engine performance and emissions control.
