Diagnostic Procedure

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
P0713-TRANSMISSION TEMPERATURE SENSOR HIGH DIAGNOSTIC TEST REFERENCE

TEST ACTION APPLICABILITY
1
NOTE: Low fluid level can be the cause of many transmission problems. If the fluid level is low locate and repair the leak then check and adjust the fluid level per the Service Information.
NOTE: Always perform diagnostics with a fully charged battery to avoid false symptoms.
With the DRBIII®, read Engine DTC's. Check and repair all Engine DTC's prior to performing any transmission symptom diagnostics.With the DRBIII®, read Transmission DTC's. Record all DTC's and 1 Trip Failures.
NOTE: Diagnose 1 Trip Failures as a fully matured DTC.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.Repair as necessary.Perform the Shift Lever Position Test. If the test does not pass, refer to Symptom test for P0706 CHECK SHIFTER SIGNAL .For Gear Ratio DTC's, check and record all CVI's.Most DTC's set on start up but some must be set by driving the vehicle such that all diagnostic monitors have run.
NOTE: Verify flash level of Powertrain Control Module. Some problems are corrected by software upgrades to the Transmission and Engine software.
NOTE: Check for applicable TSB's related to the problem.
Perform this procedure prior to Symptom diagnosis.ContinueGo To 2		 All
2 With the DRBIII®, check Transmission DTC's.
Are there any Speed Sensor DTCs present?
Yes --> Refer to the TRANSMISSION CATEGORY  and perform the appropriate test.
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .
No --> Go To 3		 All
3 With the DRBIII®, Check the STARTS SINCE SET counter for P0713.
NOTE: This counter only applies to the last DTC set.

Is the STARTS SINCE SET counter 2 or less?
Yes --> Go To 4
No --> Go To 9		 All
4 Turn the ignition off to the lock position.
Remove the Starter Relay.
CAUTION: Removal of the Starter Relay is to prevent a Transmission, NO RESPONSE, condition and disable the starter.

Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmission Adapter kit 8333-1A.
NOTE: Check connectors - Clean/repair as necessary.

Ignition on, engine not running.
With the Transmission Simulator, turn the Input/Output switch to OFF.
With the DRBIII®, monitor the TRANS TEMP VOLTS while turning the Thermistor Voltage switch to all three positions on the Transmission Simulator.
Compare the DRBIII® readings with the numbers listed on the Transmission Simulator.
Do the readings on the Transmission Simulator match the DRBIII® readings +/- 0.2 volts?
Yes --> Go To 5
No --> Go To 6		 All
5 If there are no possible causes remaining, view repair.
Repair
Replace Transmission Solenoid/TRS Assembly per the Service Information.
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .		 All
6 Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector.
Disconnect the Transmission Solenoid/TRS Assembly harness connector
NOTE: Check connectors - Clean/repair as necessary.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Measure the resistance of the Transmission Temperature Sensor Signal circuit from the appropriate terminal of special tool #8815 to the Transmission Solenoid/TRS Assembly harness connector.
Is the resistance above 5.0 ohms?
Yes --> Repair the Transmission Temperature Sensor Signal circuit for an open.
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .
No --> Go To 7		 All
7 Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector.
Remove the Transmission Control Relay.
NOTE: Check connectors - Clean/repair as necessary.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Connect a jumper wire between the Fused B+ circuit and the Transmission Control Relay Output circuit in the Transmission Control Relay connector.
Ignition on, engine not running.
Measure the voltage of the Transmission Temperature Sensor Signal circuit in the appropriate terminal of special tool #8815.
Is the voltage above 0.5 volts?
Yes --> Repair the Transmission Temperature Sensor Signal circuit for a short to voltage.
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .
No --> Go To 8		 All
8 Using the schematics as a guide, inspect the wiring and connectors. Repair as necessary. Pay particular attention to all power and ground circuits.
If there are no possible causes remaining, view repair.
Repair
Replace the Powertrain Control Module per the Service Information. WITH THE DRBIII® PERFORM QUICK LEARN .
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .		 All
9 The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wires while checking for shorted and open circuits.
With the DRBIII®, check the EATX EVENT DATA to help identify the conditions in which the DTC was set.
Were there any problems found?
Yes --> Repair as necessary.
Perform 42RLE (NGC) TRANSMISSION VERIFICATION TEST - VER 1 .
No --> Test Complete.		 All
