Function Check

Use a Tech 2 to check the TP sensor output voltage at
closed throttle.

f

The voltage should be under 0.25 volts.

f

If the reading is greater than 0.25 volts, check the
throttle shaft to see if it is binding. Check that the
throttle cable is properly adjusted, also. Refer to
Throttle Cable Adjustment. 

f

If the throttle shaft is not binding and the throttle cable
is properly adjusted, install a new TP sensor.

Cleaning and Inspection Procedure

f

Clean the IAC valve O–ring sealing surface, pintle
valve seat and air passage.

f

Use carburetor cleaner and a parts cleaning brush to
remove carbon deposit. Do not use a cleaner that
contain methyl ethyl ketone. This is an extremely
strong solvent and not necessary for this type of
deposit.

f

Shiny spots on the pintle are normal and do not
indicate misalignment or a bent pintle shaft.

f

Inspect the IAC valve O–ring for cuts, cracks or
distortion. Replace the O–ring if damaged.
