Section 05 ENGINE MANAGEMENT (POWER TEK)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
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
To gain access to TPS, do the following:
– remove air intake silencer
– loosen carburetor clamps
– install small hose pinchers (P/N 295 000 076)on
inlet and outlet coolant hoses connected to car-

NOTE: Keep throttle cable installed to avoid fur-
ther adjustment.
– properly rotate and slightly pull out carburetors
to gain access to TPS.
Connect vehicle communication kit (VCK) and use
B.U.D.S. software.
Validation of Pins 2 and 3
Disconnect TPS connector. A fault code should
appear in B.U.D.S. If so, it confirms pins 2 and 3 of
TPS connector are working. Therefore, continue
with validation of pins 1 and 3 below. If no fault
code appears, do the following.
Disconnect TPS connector.
NOTE: To disconnect TPS connector, firmly press
locking tab on top outer side of connector to re-
