DTC P0710 Transmission Fluid Temperature Sensor Circuit Malfunction

1

Perform a Transmission Control Module (TCM) Diag-
nostic System Check.
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
3. Record and then clear DTCs.
4. Select T/M Fluid Temperature on scan tool Data List.
Is the TFT sensor value less than specified value?
Is the TFT sensor value greater than specified value?

1. Turn the ignition OFF.
2. Disconnect the 10-way transmission connector

(additional DTCs will set).

3. Turn the ignition ON.
Is the TFT sensor value greater than the specified value?
1. Turn the ignition OFF.
2. Disconnect the TCM connector A.
3. Turn the ignition ON.
4. With a test light connected to B+, probe the TFT

sensor signal circuit, terminal 9 at the 10-way
transmission connector.

Does the test light illuminate?
Replace the TFT sensor.
Is the action complete?
1. Turn the ignition OFF.
2. Disconnect the 10-way transmission connector

(additional DTCs will set).

3. Turn the ignition ON.
4. Jumper the TFT ground circuit terminal 10 to the

TFT sensor signal circuit terminal 9 at the 10-way
transmission connector.

Is the TFT sensor value less than specified value?
Repair the short to ground in the TFT sensor signal
circuit as necessary.
Is the repair complete?
With a test light connected to B+, probe the TFT
sensor ground circuit at terminal 10 at the 10-way
transmission connector.
Does the test light illuminate?
1. Turn the ignition OFF.
2. Disconnect the TCM connector A.
3. Turn the ignition ON.
4. Check the TFT sensor signal circuit, terminal 9 at

the 10-way transmission connector for an open or
short to voltage.

Is a problem found?

DTC P0710 Transmission Fluid Temperature Sensor Circuit Malfunction (Cont'd)

1. Turn the ignition OFF.
2. Disconnect the TCM connector A.
3. Turn the ignition ON.
4. Check the TFT sensor ground circuit for an open.
Is a problem found?
Repair the TFT ground circuit for an open.
Is a repair complete?
Repair an open or short to voltage in the TFT sensor
signal circuit as necessary.
Is the repair complete?
Check for a poor connection at the 10-way transmission
connector and TCM connector and repair the malfunc-
tioning terminals as necessary.
Is a repair necessary?
1. Turn the ignition OFF.
2. Replace the TCM.
Is the action complete?
1. Using the scan tool, clear the DTCs.
2. Road test the vehicle within the conditions for

setting this DTC as specified in the text.

Does the scan tool indicate that this diagnostic has
run and passed?
Check if any DTCs are set.
Are there any DTCs displayed or previously recorded
at Step 3 that have not been diagnosed?

Circuit Description

The driving mode selector switch is located on the
center console and allows the driver to select the
driving mode.

When NORMAL mode is selected upshifts will occur
to maximize fuel economy. When POWER mode is se-
l e c t e d , u p s h i f t s w i l l o c c u r t o g i v e m a x i m u m
performance and the POWER mode indicator light is
switched ON.

When WINTER mode is selected, starting in second
gear is facilitated, the WINTER mode indicator light is
switched ON and the POWER mode indicator light is
switched OFF.

The DTC P0790 sets when an intermittent connection
in the mode selector switch (mode switch) circuit has
been detected. The mode switch input is rapidly
changing states. The switching frequency is greater
than 8.3 Hz.

Conditions for Setting the DTC

•

The mode switching frequency is greater than 8.3
Hz.

•

The above condition must be continuously present
for 4 state changes.

Action Taken When the DTC Sets

•

All shifts will occur as if the mode is set to NORMAL.

•

The mode indicator will always be OFF indicating
that NORMAL mode is selected.

•

The mode indicator will not respond to the changes
in switch setting.

DIAGNOSTIC TROUBLE CODE (DTC) P0790

NORMAL/PERFORMANCE SWITCH CIRCUIT MALFUNCTION

Conditions for Clearing the DTC

•

The DTC will clear after 3 seconds without the fault.

•

A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.

•

History DTCs can be cleared by using a scan tool.

Diagnostic Aids

•

This fault is caused by too many changes in the
mode input signal over a period of time.

•

Typical causes would be an intermittent connection
in the switch or wiring or an intermittent short to
ground in the wiring.

Test Description

The number(s) below refer to the step number(s) on
the Diagnostic Table.
