1 Answers
Throttle body damage manifests as follows: 1. The EPC light on the dashboard will illuminate, indicating an issue with the electronic throttle control system. 2. Difficulty starting when cold, unstable idle, and black smoke emissions. 3. The vehicle fails to start, and diagnostic tools show throttle body damage or unreliable sensor signal faults in the engine system. 4. Frequent stalling when the vehicle is coasting. 5. Failure to complete throttle body basic settings successfully; after ruling out wiring issues, battery problems, or engine control unit faults, the throttle body is determined to be damaged.
