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 room temperature. It does not validate
the over temperature functionality. To test it, the
sensor could be removed from the engine/air si-
lencer and heated with a heat gun while it is still
connected to the harness to see if the ECM will
detect the high temperature condition and gener-
ate a fault code.
FUEL SYSTEM
Refer to FUEL SYSTEM as necessary.
Check that the throttle slides move freely and
smoothly when depressing throttle lever.
Before replacing any part, check the following as
these could be causing the fault. Perform the test
while the engine is not running.
– Throttle cable adjustment too tight or there is
not enough free-play. Not returning fully to idle
stop.
– Throttle idle set screw is loose or worn.
– TPS is loose.
– Corroded or damaged wiring or connectors.
– Throttle cable or carburetor(s) has(ve) been re-
placed and the Closed Throttle reset has not
been performed.
– ECM has been replaced and the Closed Throt-
tle resethasnotbeenperformed.
DPM (Digital Performance
Management)
To test DPM manifold, refer to FUEL SYSTEM.
The DPM solenoid verification is covered in this
section.
