If voltage test is not good, check/repair wiring har-
ness. If wiring tests good, refer to
REPLACING
THE ECM
.
If voltage test is good, everything is in order (as-
suming resistance test was performed).
Replacing the TPS
Refer to
TPS ACCESS
in this subsection to gain
access to TPS.
Unplug connector from TPS.
Loosen TPS retaining screws.
Remove TPS.

Perform the
Closed Throttle And Idle Actuator
Reset
procedure. Refer to
CLOSED THROTTLE
AND IDLE ACTUATOR RESET
in this subsection.
IDLE AIR CONTROL VALVE (IACV)
Refer to the applicable
ENGINE MANAGEMENT
SYSTEM
subsection for component and connec-
tor locations.
An idle air control valve with good resistance
measurement can still be faulty. It is also pos-
sible that a mechanical failure occurs which is
not detectable without measuring the air flow.
Replacing the IACV may be necessary as a test.

IACV Access
Refer to
TPS ACCESS
in this subsection to gain
access to IACV.
Testing the IACV Resistance
Disconnect IACV from the wiring harness.
Using a multimeter, check the resistance in both
windings.
Check the resistance between pins as shown.
