Description:

This error code is triggered when the resistance in the air throttle actuator circuit is too low, indicating a short to ground. This fault may cause erratic behavior of the air throttle, potentially leading to unstable engine operation.

Reaction:

The ECU may respond by disabling the air throttle actuator to prevent uncontrollable engine speeds or other unsafe conditions.

Recommendations:

• Check for Short Circuits: Inspect the air throttle actuator and associated wiring for any signs of shorting to the vehicle’s body or other components.
• Measure and Verify Resistance: Utilize a multimeter to check resistance levels in the circuit; low resistance confirms a short.
• Rectify Electrical Faults: Repair or replace any damaged wires or components that are causing the short.
• Reset ECU and Conduct Functional Tests: After addressing the electrical issues, reset the ECU and perform tests to ensure the air throttle actuator functions correctly without recurrence of the fault.

Note:

Proper electrical functionality of the air throttle actuator is vital for accurate control over engine air intake and overall vehicle safety.
