5A-56 AUTOMATIC TRANSMISSION
DIAGNOSTIC TROUBLE CODE (DTC) P0706
TRANSMISSION RANGE SENSOR CIRCUIT RANGE/PERFORMANCE
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)
re-ceives 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.
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.
