Buyer's checklist
What to check before buying a used throttle body
- Distinguish between electronic drive-by-wire throttle bodies and traditional cable-actuated units with Idle Air Control (IAC) valves.
- Check bore diameter and butterfly valve throat for heavy carbon build-up, shaft play, or scoring along the aluminum bore wall.
- Inspect electronic sensor housing cover and connector pins for moisture entry, cracks, or burnt circuit traces.
- Verify coolant heating bypass nipple locations and vacuum port configurations, which vary by vehicle region and emission spec.
