Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies, throttle body cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Throttle Body Inspection and Cleaning

Remove the engine cover (if applicable) using a socket set.
Disconnect the electrical connector from the throttle body.
Remove any air intake ducting leading to the throttle body.
Use throttle body cleaner to spray the inside of the throttle body. Clean any carbon buildup with a soft cloth.
Inspect the throttle plate for smooth operation. Manually move it to ensure it opens and closes freely.

3. Check and Adjust Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the TPS connector.
Use a multimeter to measure the resistance across the TPS terminals while moving the throttle plate. Resistance should change smoothly.
If readings are erratic or outside specification, replace the TPS.

4. Reassemble Components

Reattach the air intake ducting to the throttle body securely.
Reconnect the throttle body electrical connector.
Reinstall the engine cover.
Reconnect the battery.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored codes.
Start the engine and allow it to idle for a few minutes to ensure proper operation.
