Throttle Actuator A Control Motor Current Range/Performance

What it means

The engine computer monitors the current drawn by the throttle motor. It has found this current outside the expected limits, usually because the motor is working too hard to move a stiff throttle plate or because of a circuit fault, and it enters limp mode.

Symptoms4

• Check engine light on, sometimes with the electronic throttle warning light.
• Loss of power and limp mode.
• Unstable idle speed.
• Occasional stalling at idle.

Possible causes5

• Carbon buildup inside the throttle body increasing the load on the motor.
• Worn motor or gears inside the throttle body.
• High resistance or partial short in the connector or wiring.
• Low battery voltage or poor ground.
• Engine computer (ECU) fault, which is rare.

How to diagnose5

1. Read all stored codes and record the freeze frame data.
2. Inspect the throttle plate with the engine off for carbon or stiff movement.
3. Check the battery and ground points.
4. Measure the throttle motor resistance against the manufacturer specification and check the wiring for shorts or high resistance.
5. Watch commanded and actual throttle position on a scan tool after cleaning.

How to fix5

1. Clean the throttle body and perform the relearn procedure.
2. Repair the faulty connector or wiring.
3. Repair poor grounds or replace a weak battery.
4. Replace the throttle body if the fault remains after cleaning and circuit repair.
5. Clear the codes and confirm the code does not return.

Repair cost

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low when cleaning or a connector repair is enough, and rises when a new throttle body is needed.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.
