1. Idle speed screw
2. Zero position stopper screw
Push the Reset buttonintheSetting section of
B.U.D.S.
Re-power up the ECM by pushing the START/RER
button momentarily.
The throttle opening displayed in B.U.D.S. should
be 0.00 (0.1 maximum).
If TPS is not within the allowed range while reset-
ting the Closed Throttle, the ECM will generate a
fault code and will not accept the setting.
Now, the idle speed screw has to be adjusted.
To do this, screw in the idle speed screw until
B.U.D.S. throttle opening displays value as per fol-
lowing table.

If throttle cable has been loosen during the proce-
dure, adjust a throttle cable.
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.
CRANKSHAFT POSITION
SENSOR (CPS)
NOTE: The CPS is used for forward and reverse.

A32C9UA
1. CPS connector
NOTE: Take into account that a CPS fault can be
triggered by missing encoder wheel teeth. First
check fault codes then check the teeth condition
if necessary. See below.
Disconnect CPS wiring harness connector. Probe
terminals coming from CPS while cranking engine.
Voltage should be within 1-2 Vac. Otherwise, in-
spect wiring and replace CPS if wiring is good.
Resistance Test
Disconnect the CPS plug connector from the
wiring harness and check the resistance of the
sensor itself.
The resistance should be between 190
and
300
.
Otherwise, replace the CPS.
If resistance tests good, reconnect the CPS and
disconnect the connector A on the ECM.
