DESCRIPTION
While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM. If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) or more for 20 seconds or more.

Transmission Fluid Temperature Sensor "A" Circuit Short To Ground (P071011)
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
