Amp Connector Pin-Out - Sea-doo RX Shop Manual

Section 05 ENGINE MANAGEMENT (DI)
Subsection 03 (COMPONENT INSPECTION AND ADJUSTMENT)
The resistance value of a temperature sensor may
test good at a certain temperature but it might be
defective at other temperatures. If in doubt, try a
new sensor.
Also remember this validates the operation of the
sensor at ambient temperature. It does not vali-
date the over temperature functionality. To test it,
the sensor could be removed from the engine/
muffler and heated with a heat gun while it is still
connected to the harness to see if the MPEM will
detect the high temperature condition and gener-
ate a fault code.
When working with injectors, the resistance value
might test good while the complete current would
not flow through the wire when pulsating current
is supplied to the injector in its normal operation.
A solution would be to use a jumper wire to direct-
ly supply the injector from the MPEM. If it now
works, replace the defective wire. A Noid light
(available from after-market tool/equipment sup-
pliers) may also be used to validate the injector
operation.
