5A-56 AUTOMATIC TRANSMISSION

SSANGYONG MY2002

Circuit Description

The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmis sion case. The TR sensor Indicates to the
TCM which gear position has been selected by way of
a varying resistance.

The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever
(PRND321). The Transmission Control Module (TCM)
receives that signal with a voltage varying from 0 V to
5 V. DTC P0707 sets when the TR sensor signal is
faulty, causing the gear lever position signal to be less
than 0.87 V.

Conditions for Setting the DTC

•

TR sensor signal is less than 0.87 V.

•

The above condition must be continuously present
for 100 milliseconds.

Action Taken When the DTC Sets

•

The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.

•

The EOBD system will record operating conditions
at the time the diagnostic fails. This information will
be stored in the Failure Records buffer.

•

Transmission range is assumed to be in the Drive
position.

•

The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.

•

Torque Converter Clutch (TCC) is disabled.

DIAGNOSTIC TROUBLE CODE (DTC) P0707

TRANSMISSION RANGE SENSOR CIRCUIT LOW INPUT

Conditions for Clearing the DTC

•

The DTC will clear when the malfunction has not
occurred 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 TR
s e n s o r i n p u t t e r m i n a l s h a s b e e n b e l o w o n
acceptable level for a significant length of time.

•

This would typically be caused by a short to ground
in the wiring to, or within, the inhibitor switch which
has caused the signal at the TCM to read about 0
V.

•

Inspect the wiring for poor electrical connections
at the TCM and at the TR sensor connector. Look
for possible bent, deformed or damaged terminals.
Also, check for chafed wires that could short to bare
metal or other wiring.

•

In searching for a possible intermittent short or open
condition, move or massage the wiring harness
while observing the test equipment for a change.

Test Description

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

3. This step simulates a DTC P0708 condition. If the

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

5A-58 AUTOMATIC TRANSMISSION

SSANGYONG MY2002

Circuit Description

The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmission case. The TR sensor Indicates to the
TCM which gear position has been selected by way of
a varying resistance.

The transmission range sensor is faulty, causing the
gear lever position signal to be greater than 4.12 V.

Conditions for Setting the DTC

•

TR sensor signal is greater than 4.12 V.

•

The above condition must be continuously present
for 100 milliseconds.

Action Taken When the DTC Sets

•

The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.

•

The EOBD system will record operating conditions
at the time the diagnostic fails. This information
will be stored in the Failure Records buffer.

•

Transmission range (gear lever) is assumed to be
in the Drive position.

•

The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.

•

Torque Converter Clutch (TCC) is disabled.

•

Manually initiated downshifts will not be available.

DIAGNOSTIC TROUBLE CODE (DTC) P0708

TRANSMISSION RANGE SENSOR CIRCUIT HIGH INPUT

Conditions for Clearing the DTC

•

The DTC will clear when the malfunction has not
occurred 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 shift
lever input terminals has been above an acceptable
level for a significant length of time.

•

This would typically be caused by a loose
connection or an open or short to B+ in the wiring
to, or within, the inhibitor switch which has caused
the signal at the TCM to read 5 V.

•

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 TR sensor 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
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.
