How to Perform Throttle Body Matching After Cleaning?
1 Answers
After cleaning the throttle body, there are two methods for matching: one is idle speed value learning using a diagnostic tool, and the other is manual learning. After throttle body cleaning, visit a repair shop to perform idle speed matching with a diagnostic tool. This ensures proper calibration of ignition timing and the engine's basic idle speed value, guaranteeing stable idle speed during driving and optimal fuel economy. Throttle body matching primarily aims to maintain the engine's optimal working condition by adjusting idle speed, controlling fuel injection volume, and modifying shift points. The vehicle's computer requires real-time status data input from the throttle body. When data changes, the computer automatically adjusts accordingly. If values exceed preset parameters, the engine may exhibit abnormal operation faults.
