Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to check for error codes related to the throttle position sensor.
2
Inspect the wiring and connectors leading to the TPS for any signs of damage or corrosion.
3
Verify the TPS voltage output using a multimeter while manually moving the throttle plate.

Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Screwdriver set
Ensure the vehicle is parked on a level surface and the engine is off.

2. Disconnect the Battery

Using a socket wrench, disconnect the negative battery terminal to prevent any electrical shorts.
Ensure that you wait at least 10 minutes before proceeding with any electrical work to allow systems to power down.

3. Locate the Throttle Position Sensor

Open the hood and locate the throttle body, which is typically found between the air intake manifold and the intake manifold.
Identify the TPS, which is mounted directly on the throttle body.

4. Reset the Throttle Position Sensor

Reconnect the battery terminal.
Start the engine and let it idle for about 5 minutes without touching the throttle pedal to allow the ECU to learn the new TPS position.
Turn off the engine, then turn the ignition key to the "ON" position (but do not start the engine) for 10 seconds, then turn it off again.

5. Finalize the Reset

Start the engine and check if the throttle response is normal.
If the check engine light is still illuminated, use the OBD-II scanner to clear any existing error codes.
