WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

1) DETERMINE IF RELATED TRANSMISSION TEMPERATURE DTCS ARE PRESENT
With the scan tool, check Transmission DTCs.

Are there any other Transmission Temperature Sensor related DTCs present?

Yes
1. Refer to the appropriate Engine ELECTRICAL DIAGNOSTICS article and perform the applicable diagnostic procedure.
No
1. Go to 2).
2) CHECK TO SEE IF DTC IS ACTIVE
With the scan tool, view DTCs.

Is the status Active for this DTC or is the STARTS SINCE SET counter 2 or less?

Yes
1. Go to 3).
No
1. Go to 4).
3) PCM AND WIRING
Turn the ignition off to the lock position.

Remove the Ignition Switch Feed fuse from the TIPM.

CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.

WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in personal injury or death.

Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmission Adapter kit.

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 scan tool, monitor the Transmission Temperature Voltage while turning the Thermistor Voltage switch to all three positions on the Transmission Simulator.

Compare the scan tool readings with the numbers listed on the Transmission Simulator.

Do the readings on the Transmission Simulator match the scan tool readings ± 0.2 volts?

Yes
1. Replace Transmission Solenoid/TRS Assembly per the Service Information.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage or terminal push out. Pay particular attention to all power and ground circuits. Check for any Service Bulletins for any possible causes that may apply. If no problems are found, replace and program the PCM per the Service Information. With the scan tool, perform QUICK LEARN.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
4) INTERMITTENT WIRING AND CONNECTORS
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 scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
No
1. Test Complete.
