General Description 

The ATF temperature sensor is a thermistor type sensor whose resistance changes according to the change in 
ATF temperature. The powertrain control module (PCM) sends a 5 V reference voltage to the grounded sensor

through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM 
detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM 
detects a low signal voltage. 

If the ATF temperature sensor signal does not change, the PCM detects a malfunction and a DTC is stored.

Malfunction Threshold 

1. Stuck at Low temperature 

The ATF temperature rise is 9 °F (5 °C) or less after the ignition switch is turned ON, and the current 
ATF temperature is -4 °F (-20 °C) or less for at least 5 minutes. 

2. Stuck at High temperature 

The ATF temperature drop is -9 °F (-5 °C) or less after the ignition switch is turned OFF, and the current 
ATF temperature is 230 °F (110 °C) or more for at least 20 seconds. 

Driving Pattern 

1. Stuck at Low temperature 

Start the engine with engine coolant temperature at 95 °F (35 °C) or less, and warm up the engine until 
the engine coolant temperature reaches 158 °F (70 °C) or more. Then drive the vehicle at a speed of 19 
mph (30 km/h) or more with the throttle position at 4.0 ° or more for at least 5 minutes. 

2. Stuck at High temperature 

Turn off the engine with the engine coolant temperature at 158 °F (70 °C) or more. Restart the engine 
after the engine coolant temperature drops to 95 °F (35 °C) or less, and warm up the engine until the 
engine coolant temperature reaches 158 °F (70 °C), and wait for at least 20 seconds. 



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the indicator 

When a malfunction is detected, the D indicator blinks, and the DTC and the freeze frame data are stored in the 
PCM memory. The MIL does not come on. 

Conditions for clearing the DTC 

The DTC and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting 
the battery.

DTC P0712 (28): ADVANCED DIAGNOSTICS

DTC P0712: SHORT IN ATF TEMPERATURE SENSOR CIRCUIT 

Fig. 95: ATF Temperature Sensor Circuit Diagram 

General Description 

The ATF temperature sensor is a thermistor type sensor whose resistance changes according to the change in 
ATF temperature. The powertrain control module (PCM) sends a 5 V reference voltage to the grounded sensor 
through a pull-up resistor. When the ATF temperature is low, the sensor resistance increases and the PCM 
detects a high signal voltage. As the ATF temperature rises, the sensor resistance decreases and the PCM 
detects a low signal voltage. 

When the ATF temperature sensor signal voltage to the PCM is under the specification, indicating that the 
temperature is above the specification (a short to ground), a malfunction is detected and a DTC is stored.
