ELECTRONIC FUEL INJECTION
THROTTLE POSITION SENSOR (TPS)
Operation Overview
The throttle position sensor (TPS) is used to indicate throttle
plate angle to the ECU.
Mounted on the throttle body and operated directly off the end
of the throttle shaft, the TPS works like a rheostat, varying the
voltage signal to the ECU in direct correlation to the angle of the
throttle plate. This signal is processed by the ECU and compared
to the internal pre-programmed maps to determine the required
fuel and ignition settings for the amount of engine load.
NOTE: The correct position of the TPS is
established and set at the factory. Do not loosen the
TPS or alter the mounting position. If the TPS is
repositioned, replaced or loosened it must be re-
calibrated by performing “TPS Initialization.”
TPS Test Procedure
The throttle position sensor (TPS) is a non-serviceable item. If
it is faulty, it must be replaced. It can be tested using the
following method:
NOTE: Before proceeding with any of the following
measurements or tests, it’s extremely important to
verify the throttle body bore is clean of any carbon
build-up. Remove the intake boot and inspect the
throttle body bore. If required, remove the throttle
body and clean the bore using carburetor cleaner.
Set up the TPS Tester (PU-47082), according to the instructions
that accompanied the tester. Make sure that the 9 volt battery is
new.
As mentioned in the instructions included with the tester, be sure
the TPS tester is set up along with the TPS Tester Regulator
(4010264).
NOTE: If your dealership sells Polaris snowmobiles,
you may already have this regulator from TPS tool
PN 2201519. If you do not have this regulator, you
must order one from SPX at 1-800-328-6657.
