Throttle Body: Service and Repair
Throttle Body Cleaning
Note:
Under normal or severe operating conditions, it is possible for the throttle body to build deposits in the air flow area around the throttle blade,
and/or near the Idle Air Control (IAC) inlet. These deposits can cause driveability problems that may or may not appear as a fault code in
diagnosis.
1.
Visually inspect the throttle body for cracks, deformation or tampering. If there is any visible damage to throttle body, replace throttle body.
2.
Remove the throttle body.
3.
While holding the throttle open, carefully clean any deposits from the throttle body air flow area, including the back of throttle plate. Insure that
the edges of the throttle blade, and throttle bore are free of deposits.
Note:
Do not use harsh abrasives or tank solvent washing to clean the throttle body.
4.
Inspect the intake plenum and clean if deposits are visible.
3.
Install throttle body, and perform Throttle Body Minimum Airflow Test. SEE Powertrain Management/Computers and Control Systems
/Testing and Inspection/Procedures
4.
If minimum air flow is still not within specifications, the problem is not caused by the throttle body.
