Circuit Description
The Transmission Fluid Temperature (TFT) sensor is a
thermistor located in the solenoid wiring loom within
the valve body of the transmission. This sensor is a
typical Negative Temperature Coefficient (NTC) resistor
with low temperatures producing a high resistance and
high temperatures producing a low resistance.
If the transmission fluid temperature exceeds 135 °C
(275 °F), the TCM will impose converter lock-up at lower
vehicle speeds. Favour a lower gear to increase engine
speed, and in some vehicles flashes the mode indicator
lamp. This results in maximum oil flow through the exter-
nal oil cooler and eliminates slippage in the torque
converter. Both these actions combine to reduce the
oil temperature in the transmission.
The DTC P0710 sets when the TFT sensor signal is not
feasible.
Conditions for Setting the DTC
Transmission fluid temperature sensor signal is
greater than 4.88 volts (immediate detection).
Transmission fluid temperature sensor signal is less
than 0.21 volts (immediate detection).
Transmission temperature has not changed by 2 °C
in 15 minutes since ignition on and temperature is
less than 20 °C or greater than 125 °C.
Action Taken When the DTC Sets
Transmission fluid temperature is assumed to be
120 °C (248 °F).
All shifts will be firm until the transmission has
warmed up because a high transmission fluid
temperature is assumed.
DIAGNOSTIC TROUBLE CODE (DTC) P0710
TRANSMISSION FLUID TEMPERATURE SENSOR CIRCUIT
MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc
curred for 3 seconds.
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
The voltage measured by the TCM across the trans-
mission fluid temperature input terminals has been
outside acceptable levels.
If the DTC sets when an accessory is operated,
check for a poor connection or excessive current
draw.
Inspect the wiring for poor electrical connections
at the TCM and at the 10-way transmission
connector. Look for possible bent, backed out,
deformed or damaged terminals. Check for weak
terminal tension as well. Also, check for chafed wires
that could short to bare metal or other wiring. Inspect
for broken wires inside the insulation.
In searching for a possible intermittent short or open
condition, move or massage the wiring harness
while observing test equipment for a change.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
5. This step simulates a DTC P0710 condition. If the
scan tool displays the specified value, the TFT
sensor signal circuit and the TCM are OK.

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-
lected, upshifts will occur to give maximum
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.
3. Check mode switch signal circuit for an
intermittent open / short
5. Check mode switch ground circuit for an
intermittent open / short
8. Check mode switch feed circuit for an intermittent
open / short
