Test Description

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

4. This step simulates a DTC P0707 condition. If the

scan tool displays the specified value, the TR
sensor signal circuit and the TCM are OK.

DTC P0707 Transmission Range Sensor Circuit High Input

1

Perform a Transmission Control Module (TCM)  Diag-
nostic System Check.
Is the check performed?
1. Turn the ignition ON, with the engine OFF.
2. Install a scan tool.
3. Record and then clear DTCs.
4. Operate the vehicle within the conditions for

setting this DTC as specified in the text.

5. Review the TR Sensor value on the scan tool.
Is the TR Sensor value greater than the specified value?
1. Turn the ignition OFF.
2. Disconnect the Transmission Range (TR) sensor

connector.

3. Turn the ignition ON.
4. With a test light connected to ground, probe the

TR sensor signal circuit at terminal 1.

Is the TR sensor value less than specified value?
With a test light connected to B+, probe the TR
sensor ground circuit at terminal 2.
Does the test light illuminate?
Check for a poor connection at the TR sensor connector
and repair the malfunctioning terminals as necessary.
Is a repair necessary?
Replace the TR sensor.
Is the action complete?
1. Turn the ignition OFF.
2. Disconnect the Transmission Control Module (TCM)

connector A.

3. Check the TR sensor signal circuit at terminal 1 for an

open or short to voltage and repair as necessary.

Is a repair necessary?
Check the TR sensor ground circuit at terminal 2 for
an open and repair as necessary.
Is a repair necessary?
Check for a poor connection at the TCM connector
and repair the malfunctioning 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 DTCs previously
recorded at Step 2 that have not been diagnosed?

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.

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.

5. This step simulates a DTC P0710 condition. If the

scan tool displays the specified value, the TFT
