Fig. 79 Engine Coolant Temperature Sensor Location-SOHC:
1. With the key off, disconnect wire harness connector from coolant temperature sensor (Fig. 79).
Fig. 27 Engine Coolant Temperature Sensor:
2. Connect a high input impedance (digital) volt-ohmmeter to terminals A and B (Fig. 27). The ohmmeter should read as follows:
- Engine/Sensor at normal operating temperature around 200°F should read approximately 700 to 1,000 ohms.
- Engine/Sensor at room temperature around 70°F ohmmeter should read approximately 7,000 to 13,000 ohms.
3. Test the resistance of the wire harness between the PCM 60-way connector terminal 28 and the sensor harness connector. Also check for continuity between PCM 60-way connector terminal 51 and the sensor harness connector. Refer to electrical diagrams for circuit information. If the resistance is greater than 1 ohm, repair the wire harness as necessary.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
