5A-54 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 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 P0706 sets when the TR sensor signal is not
feasi ble.
Conditions for Setting the DTC
•The engine temperature is greater than 60 °C (140 °F).
The engine speed is greater than 2000 RPM and
less than 4000 RPM.
Engine load is greater than 60 %.
DTCs P0707, P0708, P1703 and P1719 are not set.
Transmission temperature is greater than 0 °C (32 °F)
or if P0710 is present the engine coolant
temperature is greater than 60 °C (140 °F).
The TR sensor indicates that the transmission is in
a neutral state, however the engine output torque
indicates that a drive gear load is present. This
condition must be continuously present for 5
seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P0706
TRANSMISSION RANGE SENSOR CIRCUIT RANGE/PERFORMANCE
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.
TR signal 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.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc-
curred for 30 seconds and TR is in P, R, N or D.
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
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
ter-minals. 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 in-sulation.

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.

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
sensor input terminals has been below on
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.
