TRIP COUNTER displays "0", return to appropriate test(s). If DTC
SPECIFIC GOOD TRIP COUNTER displays one or more, repair is complete.
Go to step 9).
3) If coming to this test from a mis-fire DTC test, go step
7). If coming to this test from other than a mis-fire DTC test, use
scan tool to monitor pretest enabling conditions until all conditions
have been met. Once all enabling conditions are met, observe
appropriate monitor for DTC on scan tool and go to next step.
4) Using scan tool, monitor SIMILAR CONDITIONS to attempt to
duplicate conditions that vehicle was operating at when DTC was set.
If conditions can be duplicated, GOOD TRIP COUNTER will change to one
or more. Monitor operation may be observed on scan tool. All specified
enabling conditions for specified DTC must be met before PCM will
operate monitor. Go to next step.
5) Turn ignition off for 10 seconds. Start engine and allow
it to idle for 2 minutes while monitoring scan tool. If STARTS SINCE
SET and DTC SPECIFIC GOOD TRIP COUNTER change to one or more, repair
is complete. Go to step 9). If STARTS SINCE SET and DTC SPECIFIC GOOD
TRIP COUNTER do not change to one or more, go to next step.
6) Using scan tool, read DTCs. If any DTC exists, return to
appropriate test(s). If no other DTC exists, go to next step.
7) Using scan tool, monitor SIMILAR CONDITIONS to attempt to
duplicate conditions that vehicle was operating at when DTC was set.
If conditions can be duplicated, MISFIRE GOOD TRIP COUNTER will change
to one or more. If MISFIRE GOOD TRIP COUNTER changes to one or more,
test is complete. Go to step 9). If MISFIRE GOOD TRIP COUNTER does not
change to one or more, go to next step.
8) Using scan tool, read DTCs. If any DTC exists, return to
appropriate test(s). If no other DTC exists, go to next step.
9) Turn ignition on, with engine off. Using scan tool, erase
DTCs. Turn ignition off. Disconnect scan tool. Test is complete.
REMOVAL & INSTALLATION
GOVERNOR PRESSURE SENSOR, GOVERNOR PRESSURE SOLENOID &
TRANSMISSION FLUID TEMPERATURE SENSOR
NOTE: Transmission fluid temperature sensor is integral with
governor pressure sensor.
Removal
1) Raise and support vehicle. Drain transmission fluid.
Remove transmission oil pan and filter. Disconnect harness connectors
from governor pressure solenoid and sensor.
2) Remove pressure solenoid retainer-to-governor body screws.
Separate solenoid retainer from governor and pull solenoid from
governor body.
3) Remove governor body-to-valve body bolts. Separate
governor body from valve body. Remove governor body and gasket. Remove
retainer clip holding pressure sensor to governor body and remove
pressure sensor.
Installation
1) Clean all gasket surfaces. Lubricate NEW "O" ring with ATF
and install on pressure sensor. Push pressure sensor into governor
body and install retainer clip. Position governor body on valve body
with NEW gasket and install governor body-to-valve body bolts.
2) Lubricate NEW "O" ring with ATF and install on pressure
solenoid. Push solenoid into governor body. Install solenoid retainer.
Reconnect harness connectors to pressure solenoid and sensor. To
complete installation, reverse removal procedure.
OUTPUT SHAFT SPEED SENSOR
NOTE: Transmission output shaft speed sensor may also be referred
to as transmission shaft speed sensor or shaft speed sensor.
Removal & Installation
1) Disconnect electrical connector from output shaft speed
sensor, located on case of overdrive unit. Remove output shaft speed
sensor with "O" ring.
2) To install, reverse removal procedure using NEW "O" ring.
Tighten output shaft speed sensor to specification.
