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

D

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

D

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:

D

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.

D

Damaged harness – Inspect the wiring harness for
damage.

D

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.

4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P0219 (Flash DTC 11) 

Engine Over Speed Warning

060RW133

Circuit Description

The CKP reference signal is produced by the crankshaft
position (CKP) sensor.  During one crankshaft revolution,
CKP  crankshaft reference pulses will be produced.  The
Engine Control Module ECM uses the CKP reference
signal to calculate engine RPM and crankshaft position.

Action Taken When the DTC Sets

D

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

D

DTC P0219 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.

Diagnostic Aids

Check for:

D

Poor connection – Inspect the CKP harness and
connectors for improper mating, broken locks,
improperly formed or damaged terminals, and poor
terminal-to-wire connection.

D

Damaged X57 – Inspect the X57 for damage.
