6E–109 4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P1217 (Flash DTC 36)
High Oil Temp Warning
060RW129
Circuit Description
The engine oil temperature (OT) sensor is a thermistor
mounted on a oil manifold. The Engine Control Module
ECM applies a voltage (about 5 volts) through a pull-up
resistor to the OT signal circuit. When the engine oil is
cold, the sensor (thermistor) resistance is high, therefore
the ECM will measure a high signal voltage. As the
engine oil warms, the sensor resistance becomes lower,
and the OT signal voltage measured at the ECM drops.
Action Taken When the DTC Sets
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P1217 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.
Diagnostic Aids
Check for the following conditions:
Poor connection at ECM – Inspect harness connectors
for backed-out terminals, improper mating, broken
locks, improperly formed or damaged terminals, and
poor terminal-to-wire connection.
Damaged harness – Inspect the wiring harness for
damage.
High Oil Temperature Warning may sometimes be
given due to High Coolant Temp Warning. On this
occasion, recognize DTC P0217 and give priority to
High Coolant Temp Warning.

Vehicle Speed Sensor (VSS)
Removal Procedure
CAUTION: The VSS is located on the right side of
the transfer case just ahead of the rear propeller
shaft and very close to the exhaust pipes. Be sure
that the exhaust pipes are cool enough to touch
before trying to remove the VSS. If the pipes are hot,
you could be burned.
1. Disconnect the negative battery cable.
2. Disconnect the VSS electrical connector.
TS23748
3. Remove the bolt and the clamp securing the VSS in
place.
IMPORTANT:H a v e a c o n t a i n e r r e a d y t o c a t c h a n y f l u i d
that leaks out when the VSS is removed from the transfer
case.
TS23780
4. Remove the VSS from the transfer case by wiggling it
slightly and pulling it straight out.
Inspection Procedure
1. Inspect the electrical connector for signs of corrosion
or warping. Replace the VSS if the electrical
connector is corroded or warped.
2. Inspect the VSS driven gear for chips, breaks, or worn
condition. Replace the VSS if the driven gear is
chipped, broken or worn.
3. Inspect the O-ring for wear, nicks, tears, or
looseness. Replace the O-ring if necessary.
Installation Procedure
1. Install the VSS in the transfer case with the notch for
the connector facing the rear.
2. Secure the VSS in place with the clamp and the bolt.
Tighten
Tighten the bolt to 16 Nꞏm (12 lb ft.).

4. Check the transfer case oil level. Add fluid if
necessary.
