Activate the throttle lever a few times. Make
sure throttle cam of throttle body rests against
idle speed screw without any tension on the
cable.
Using the VCK with B.U.D.S., perform the wide
open verification. In Monitoring tab check if
throttle opening is within 82° to 86° when in wide
open position on throttle lever.
Closed Throttle Reset
Perform the Closed Throttle reset as described in
THROTTLE POSITION SENSOR (TPS) below.
THROTTLE POSITION SENSOR
(TPS)
General
The throttle position sensor (TPS) is a potentiome-
ter that sends a signal to the ECM which is propor-
tional to the throttle shaft angle.
A32C9RA
TYPICAL — THROTTLE POSITION SENSOR (TPS)
IMPORTANT: Prior to testing the TPS, ensure
that mechanical components/adjustments are
adequate according to THROTTLE BODY above.
The ECM may generate several fault codes per-
tainingtotheTPS.RefertoEMSFAULTCODES
in DIAGNOSTIC PROCEDURES section for more
information.
Wear Test
While engine is not running, activate throttle and
pay attention for smooth operation without physi-
cal stops of the cable.
Using the vehicle communication kit (VCK) with
the B.U.D.S. software, use the Throttle Opening
display under Monitoring.
Slowly and regularly depress the throttle. Ob-
serve the needle movement. It must change
gradually and regularly as you move the throttle.
If the needle “sticks”, bounces, suddenly drops
or if any discrepancy between the throttle move-
ment and the needle movement is noticed, it
indicates a worn TPS that needs to be replaced.
Voltage Test
Check the voltage output from ECM to the throttle
position sensor.
