Description:

This error code is triggered when the resistance in the air throttle actuator circuit is too low, indicating a short to ground. This could lead to excessive current flow that might damage the actuator or associated electrical components.

Reaction:

To protect the actuator and circuit, the ECU may limit functionality or shut down the actuator to prevent further damage.

Recommendations:

• Inspect for Shorts to Ground: Check the circuit for exposed wires or connections that might contact the vehicle frame or other grounded surfaces.
• Test Circuit Resistance: Utilize a multimeter to verify low resistance readings and identify the location of the short.
• Rectify Electrical Short: Repair any issues causing the short by insulating exposed wires, securing loose connections, or replacing damaged components.
• Reset ECU and Perform Functional Testing: After electrical repairs, reset the ECU to clear the fault and conduct functional tests to ensure the actuator operates correctly without recurrence of the fault.

Note:

Proper maintenance of the air throttle actuator’s electrical system is crucial for preventing shorts and ensuring the longevity and efficiency of the engine’s air intake system. Regular inspections are recommended to maintain system integrity.
