DTC P2740 Transmission Fluid Temperature Sensor ºBº
Circuit
DTC P2742 Transmission Fluid Temperature Sensor ºBº
Circuit Low Input
DTC P2743 Transmission Fluid Temperature Sensor ºBº
Circuit High Input
CIRCUIT DESCRIPTION
The ATF temperature sensor converts fluid temperature into a resistance value which is input in to the ECM.
ATF temperature sensor No.2 is on the transmission and just before the oil cooler inlet pipeline.
If ECM detects the abnormally high temperature of ATF by this sensor, it draws driver's attention by illuminat-
ing the warning lamp.
HINT:

The temperature of ATF easily raises when towing, climbing hills and in traffic, etc.

If the ATF temperature sensor No.2 shorts, the signal that indicates the ATF temperature is 150C
(302F) or higher is input in ECM.
Vehicle conditions when sensor is in normal and when the vehicle is in short are indicated in the table
below.
