Default ETC Throttle Body Cleaning Procedure

1. Remove the throttle body from the intake manifold.

CAUTION: Use only Mopar Brake Parts Cleaner, p/n 04897150AB or 04897151AB, as
the use of other cleaners may damage components of the throttle body.
Use this cleaner only in a well ventilated area. Do not let this cleaner
come in contact with the skin. Rubber or butyl gloves are recommended.
Wash thoroughly after use. Avoid eye contact. Avoid ingesting.

2. While holding the throttle open, spray the throttle body bore with Mopar Brake Parts
Cleaner, p/n 04897150AB or 04897151AB. Spray the entire throttle body bore and the
manifold side of the throttle plate.

3. Use a soft cloth to help break loose deposits to clean the throttle body bore and
throttle plate. While holding the throttle open, clean both the top and bottom of the
throttle body bore. Also clean the manifold side and edges of the throttle plate.

NOTE: Take due care not to scratch, bend, or dent throttle plate and/or throttle body
bore.

NOTE: It is important this cleaning operation be performed thoroughly and
completely. The edge of the throttle plate and the portion of the throttle body
bore that is in the closest proximity to the closed throttle plate is the most
critical area where the cleaning should be concentrated. This area must be
free of all deposits when the cleaning is completed.

4. Spray the throttle body with, Mopar Brake Parts Cleaner, p/n 04897150AB or
04897151AB, and then blow dry with compressed shop air. Inspect for any foreign
material which may have been left behind during the cleaning process.

CAUTION: Do not apply shop air pressure directly into the throttle shaft and throttle
body housing holes.

5. Open and close the throttle plate on the throttle body to verify that there is no
increased effort when moving from the closed position. If the condition is corrected,
proceed to the next step. If the increased effort still exists, then some other condition
exists with the throttle body and further diagnosis and repair will be necessary and will
not be covered by this repair procedure.

6. Install the throttle body on the intake manifold.

7. Open and close the throttle to verify that there is no increased effort when moving from
the closed throttle position. If the condition is corrected, proceed to the next step. If the
increased effort still exists, then some other condition exists with the throttle linkage
and further diagnosis and repair will be necessary.
