Does the throttle need to be matched after cleaning?
1 Answers
Cable throttles do not require matching, while electronic throttles need to be matched. Below are the methods for throttle matching: 1. Manual matching: Turn the ignition key on and off several times in a row. The vehicle's onboard computer will delete the original throttle memory and store the new throttle data. Start the vehicle, and if it runs normally, the matching is complete. 2. Power-off matching: After replacing the throttle, you can disconnect the negative terminal of the battery, wait for one minute, and then reconnect it. This process will clear the original memory of the onboard computer and restore it to factory settings. Start the vehicle, and if it runs normally, the matching is successful. This method is only suitable for low-end vehicles and cannot be used for high-end vehicles. 3. Diagnostic tool matching: Use a dedicated automotive diagnostic tool for matching. After entering the system, select "Action Test" and click "Adaptive Value Reset." Repeat this process several times. Start the vehicle, and if it runs normally, the matching is successful. 4. Matching with the old throttle position sensor: After installing a new throttle, if issues like unstable idle speed or excessively high idle speed occur, disconnect the new throttle position sensor plug and connect it to the old throttle position sensor. Start the vehicle, and once it runs normally, turn off the engine. Then reconnect the wiring harness to the new throttle.
