S10/T10 P/U 2WD V6-4.3L VIN W (1997)
Outside Temperature Display: Service and Repair
The temperature sensor is mounted to the hood latch support bracket and is located near the center of the grille opening. An electrical connector attaches
the sensor to the front headlamp harness. The sensor itself is a thermistor which provides a resistance that varies with temperature. If the thermistor is
suspected of being defective, an ohm-meter can be used to measure the resistance of the sensor. The sensor should be disconnected from the harness to
conduct the measurement. The resistance values of the sensor should be as shown in the table.
The electronic module has the capability to detect a short circuit or an open circuit in the temperature sensor circuitry. The display will show "SC" in the
temperature area if a short circuit is detected and will show "OC" if an open circuit is detected. If either display exists, the short or open condition must
be located in the wire harness between the sensor and the electronic module.
