THROTTLE BODY
1. Throttle position sensor (TPS)
2. Screws
Install the new TPS.
Apply Loctite 243 on the TPS retaining screws,
then torque to 3 N•m(27lbf•in).
Reinstall remaining removed parts.
Proceed with the CLOSED THROTTLE AND IDLE
ACTUATOR RESET. See below.
Closed Throttle and Idle Actuator Reset
NOTE: This operation performs a reset of the val-
ues in the ECM.
This reset is very important. The setting of the
TPS will determine the basic parameters for all
fuel mapping and several ECM calculations and
the setting of the idle bypass valve will determine
the basic parameters for the idle speed control of
the engine.
NOTE: Resetmustbedoneeachtimethethrottle
position sensor (TPS) is loosened or removed or
throttle body is replaced or ECM is replaced.
CAUTION: An improperly set TPS or idle
bypass valve may lead to poor engine perfor-
mance.
Use the vehicle communication kit (VCK) with the
B.U.D.S. software to perform this adjustment.
Ensure the throttle body plate stop lever rest
against its stopper. Open throttle approximately
one quarter then quickly release. Repeat 2 - 3
times to settle throttle plate. If stopper does not
rest against its stop lever, perform throttle cable
adjustment. Refer to THROTTLE BODY in AIR
INDUCTION SYSTEM above.
Click on the Reset buttonintheSetting section of
B.U.D.S.
NOTE: No message will be displayed if operation
is successful. If operation is wrong, an error mes-
sage will be displayed.
NOTE: There is no idle speed adjustment to
perform. The ECM takes care of that. If TPS is
not within the allowed range while resetting the
Closed Throttle and Idle Actuator,theECM
will generate a fault code and will not accept the
setting.
Start engine and make sure it operates normally
through its full engine RPM range. If fault codes
appear, refer to SYSTEM FAULT CODES in the DI-
AGNOSTIC PROCEDURES section for more infor-
mation.
IDLE BYPASS VALVE
An idle bypass valve with good resistance mea-
surement can still be faulty. It is also possible
that a mechanical failure occurs which is not de-
tectable without measuring the air flow. Replac-
ing the idle bypass valve may be necessary as a
test.
Resistance Test
Disconnect idle bypass valve from the wiring har-
ness.
Using a multimeter, check the resistance in both
windings.
