Ski-Doo Ski Doo MX Z 2005 [1192/1429] Throttle position sensor tps
Section 06 ENGINE MANAGEMENT (4-TEC)
Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)
Connect the CPS, CTS and OPS to the wiring har-
ness.
NOTE: Routing of the harness for CAPS, CTS and
OPS has to be between the intake manifold and
cylinder 1, underneath the water hoses.
Use locking ties to attach the cables for the CTS
on the water hose and on the sensor itself then for
the OPS on the T-fitting and on the sensor itself.

Install all remaining parts, which have been re-
moved.
Do not forget to connect ATS connector to the ATS
on the air intake silencer.
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.

1. Throttle position sensor (TPS)
IMPORTANT: Prior to testing the TPS, ensure
that mechanical components/adjustments are
adequate according to THROTTLE BODY in AIR
INDUCTION SYSTEM above.
The EMS may generate several fault codes per-
taining to the TPS. Refer to SYSTEM FAULT
CODES 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 that the TPS needs to be replaced.
Voltage Test
Check the voltage output from ECM to the desired
throttle position sensor.
