Automatic Transaxle

Coolant Temperature Sensor:

PURPOSE
The PCME utilizes temperature sensor information in its calculations for outputs such as air/fuel ratio control and emission devices.

LOCATION
Right end of engine near oil filler.

OPERATION
The sensor is a thermistor device whose resistance varies with changes in coolant temperature. The PCME sends a reference voltage to the sensor and measures changes in resistance as engine temperature fluctuates.

COOLANT TEMP. RESISTANCE (K OHMS)
20°C (68°F) 35.5 - 39.2
60°C (140°F) 7.20 - 7.90
80°C (176°F) 1.13 - 1.25
