Throttle Body: Testing and Inspection

Throttle Body Test




1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
2. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on, then let it idle.
3. Check the TP SENSOR A in the DATA LIST with the HDS. The reading should be above 2.73%.
- If it is not, clean the throttle body.
