5. Remove the TPS Mounting Bolts or Screws
- Use a socket or screwdriver to remove the bolts or screws that secure the TPS to the throttle body.
- There might be one or more bolts or screws, depending on the vehicle.
6. Remove the Old TPS
- Once the bolts or screws are removed, you should be able to lift the TPS off the throttle body.
- Be careful not to drop any of the small components that might come loose during removal.
7. Clean the Throttle Body Mounting Surface
- Use a rag and some throttle body cleaner to clean the mounting surface of the throttle body where the TPS will be installed.
8. Install the New TPS
- Position the new TPS onto the throttle body, ensuring that the mounting holes align correctly.
- Reinstall the bolts or screws that you removed earlier, and tighten them securely.
9. Reconnect the Electrical Connector
- Reattach the electrical connector to the TPS by aligning it and pushing it in until it clicks into place.
10. Reconnect the Battery
- Reattach the negative terminal of the battery to restore power to the vehicle.
11. Start the Engine and Test
- Start the vehicle and allow it to run for a few minutes. Check the engine idle speed and note if there are any irregularities or fault codes. If everything seems to be functioning correctly, take the vehicle for a test drive to verify that the TPS replacement was successful.
Remember, if you are not confident performing these steps, it's best to consult with a qualified mechanic or refer to your vehicle's repair manual for specific instructions and safety guidelines.
