A/T. P. (Automatic Transmission Parking) Indicator Circuit
CIRCUIT DESCRIPTION
The propeller shaft and wheels are free even when the transmission shift lever is set to P as long as the
transfer shift lever is in Neutral position. The A/T.P. indicator light lights up to warn the driver that the propeller
shaft and wheels are not locked.
If the A/T.P. indicator light goes on, the transfer shift lever should be shifted to the positions other than N
position.

DTC P0710 Transmission Fluid Temperature Sensor ºAº
Circuit
DTC P0712 Transmission Fluid Temperature Sensor ºAº
Circuit Low Input
DTC P0713 Transmission Fluid Temperature Sensor ºAº
Circuit High Input
CIRCUIT DESCRIPTION
The ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM.
DTC No.DTC Detecting ConditionTrouble Area
P0710
(a) and (b) is detected momentary within 0.5 sec. when neither
P0712 or P0713 is not detected (1-trip detection logic)
(a) ATF temperature sensor resistance is less than 79 W.
(b) ATF temperature sensor resistance is more than 156 kW.
HINT:
Within 0.5 sec. the malfunction switches from (a) to (b) or from
(b) to (a)

Open or short in ATF temperature sensor No. 1 circuit

ATF temperature sensor No. 1
P0712ATF temperature sensor resistance is less than 79 W. for 0.5
sec. or more (1-trip detection logic)
ECM
P0713
ATF temperature sensor resistance is more than 156 kW. 15
minutes or more after the engine start DTC is detected for 0.5
sec. or more (1-trip detection logic)
MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 W
*1 or more than 156 kW*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will
turn on the MIL and store the DTC.
*1: 150C (302F) or more is indicated regardless of the actual ATF temperature.
*2: -40C (-40F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the OBD II scan tool or hand-held tester display.
