Wiring Diagram:

CIRCUIT DESCRIPTION
Located at the side of intake manifold or on the coolant outlet pipe, this sensor measures the temperature of the engine coolant and converts its change into that in resistance through the thermistor.

By monitoring the resistance of the coolant temperature sensor, ECM (PCM) detects the engine coolant temperature and that affects most systems under the control of ECM (PCM).

DTC Detecting Condition And Trouble Area:

DTC CONFIRMATION PROCEDURE

WARNING:
- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and a tester, on a level road.

NOTE: Check to make sure that following conditions are satisfied when using this "DTC CONFIRMATION PROCEDURE".
- Intake air temp.: -8 °C (18 °F) or higher
- Engine coolant temp.: -8 - 110 °C (18 - 230 °F)
- Altitude (barometric pressure) : 2400 m, 8000 ft or less (560 mmHg (75 kPa) or more)

1. Connect scan tool to DLC with ignition switch OFF.
2. Turn ON ignition switch and clear DTC, pending DTC and freeze frame data by using scan tool.
3. Confirm that engine coolant temp. is between 25 °C and 71 °C (77 °F and 160 °F).
4. Warm up engine to normal operating temperature and keep it at idle for 3 min. or more.
5. Drive vehicle at 35 mph, 55 km/h or higher for 3 min. or more.
6. Stop vehicle and check pending DTC and DTC.
