Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery by removing the negative terminal to prevent electrical shorts.
Allow the vehicle to cool down if it has been running.

2. Accessing the Throttle Position Sensor

Locate the throttle body, which is typically near the intake manifold.
Remove any air intake ducting or covers that obstruct access to the throttle body.
Disconnect the electrical connector from the throttle position sensor.

3. Resetting the Throttle Position Sensor

Turn the ignition key to the "ON" position without starting the engine.
Wait for approximately 10 seconds to allow the vehicle's computer to reset the TPS.
Turn the ignition off for 10 seconds.

4. Reconnecting Components

Reconnect the electrical connector to the throttle position sensor.
Reinstall any air intake ducting or covers that were removed.
Ensure all connections are secure.

5. Final Steps

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes to allow the ECU to relearn the throttle position.
Observe the engine idle and acceleration response to ensure proper operation.
