Circuit Description
The DTC will set if ATF temperature sensor converts fluid temperature into a resistance value which is input into the ECM. After 12 seconds of the engine start, the temperature of the atmosphere and that of the engine coolant is more than 14°F (-10°C).
After a normal driving for over 20 minutes and 6.6 miles (10 kilometers), the ATF temperature is less than 14°F (-10°C). Possible causes are
- Open in ATF temperature sensor circuit.
- ATF temperature sensor malfunction.
- ECM malfunction.
