Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, cleaning supplies, screwdrivers.
Ensure the vehicle is parked on a flat surface, and the engine is cool.

2. Clean Throttle Body

Step 1: Remove the air intake duct by loosening the clamps and disconnecting any sensors attached.
Step 2: Use throttle body cleaner and a soft cloth to clean the inside of the throttle body. Ensure the throttle plate moves freely.
Step 3: Reattach the air intake duct securely.

3. Inspect and Replace APP Sensor (if faulty)

Step 1: Disconnect the negative battery terminal to prevent electrical shorts.
Step 2: Locate the APP sensor on the accelerator pedal assembly.
Step 3: Disconnect the electrical connector from the APP sensor.
Step 4: Remove the sensor from the pedal assembly using the appropriate socket size.
Step 5: Install the new APP sensor and reconnect the electrical connector.
Step 6: Reconnect the negative battery terminal.

4. Check Throttle Body Connections

Step 1: Inspect the wiring harness connected to the throttle body for signs of wear or damage.
Step 2: Repair or replace any damaged wires or connectors as needed.
Step 3: Ensure all connections are secure and free from corrosion.

5. Reset the Throttle Position

Step 1: With the ignition in the "ON" position (engine off), press the accelerator pedal to the floor and release it slowly.
Step 2: Turn the ignition to the "OFF" position and then start the engine.
Step 3: Allow the vehicle to idle for a few minutes to complete the throttle relearning process.
