Transaxle temperature sensor uses a thermistor to vary signal voltage to PCM according to temperature. PCM applies and monitors a voltage to sensor. When transaxle fluid is cold sensor resistance is high. Thus, PCM will monitor a high signal voltage. As transaxle fluid warms, sensor resistance becomes less and voltage drops. At normal operating temperature of 68°F-194°F (20°C-90°C) transaxle temperature signal will measure approximately 2-4 volts.

Code P0713 will set when the following conditions are present.

Engine run time is over 1 minute.
Transaxle temperature sensor signal indicates a temperature greater than 284°F (140°C).
Above conditions for over 1.6 second.

With Code P0713 set, PCM will substitute ECT sensor value for transaxle temperature. Tech 1 will continue to display actual transaxle sensor value. Code P0713 does not illuminate the Malfunction Indicator Light (MIL).

NOTE: Test numbers refer to numbers on diagnostic chart.

Determines if conditions necessary to set Code P0713 exist.
This test determines if input circuit is shorted to ground which will cause conditions necessary for Code P0713.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
