Section 06 ENGINE MANAGEMENT (SDI)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
Check the continuity between pin 3 on wiring har-
ness TPS connector and pin 24 on wiring harness
ECM connector.
If tests are good, replace the TPS.
If voltage tests are not good, continue to check
the resistance of the rest of the TPS circuit.
Resistance Test
Reconnect the TPS.
Disconnect the connector A from the ECM.

Using a multimeter, check resistance value as per
the following table.

NOTE: The resistance value should change
smoothly and proportionally to the throttle move-
ment. Otherwise, replace TPS.
If resistance values are correct, try a new ECM.
Refer to ECM REPLACEMENT procedures else-
where in this section.
If resistance values are incorrect, replace TPS.
Replacement
Remove the throttle body as described above.
Loosen two screws retaining the TPS.
Remove TPS.

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.

Closed Throttle Reset
Ensure throttle body synchronization and throttle
cable are properly adjusted prior to performing this
setting.
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 in idle
speed control of the engine.
NOTE: Resetmustbedoneeachtimethethrottle
position sensor (TPS) is loosened or removed or
throttle body or ECM is replaced.
CAUTION: An improperly set TPS may lead to
poor engine performance.
Use the vehicle communication kit (VCK) with the
B.U.D.S. software to perform this adjustment.
Unscrew idle speed screw until the throttle body
plate stop lever rest against its zero position stop-
per screw (capped screw). If necessary, loosen
the throttle cable. Open throttle approximately
one quarter then quickly release. Repeat 2 - 3
times to settle throttle plate.
