ECU Power Source Circuit
ComponentsTransmission Fluid Temperature Sensor "A" Circuit Range/Performance (P071000)
DESCRIPTION
The No. 1 ATF temperature sensor converts the fluid temperature into a resistance
value for use by the ECM.
The ECM applies a voltage to the temperature sensor through terminal THO1 of
the ECM.
The sensor resistance changes with the ATF temperature. As the temperature becomes

Pressure Control Solenoid "C" Actuator Stuck Off (P07957F)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
