Sensor Test

1996 Chrysler New Yorker V6-3.5L VIN FSECTION Sensor Test

Coolant Temperature Sensor Resistance Test:






1. With the key off, disconnect wire harness connector from coolant temperature sensor (Fig. 58 or Fig. 59).
2. Connect a high input impedance (digital) volt ohmmeter to terminals A and B. The ohmmeter should read as follows:
- Engine/Sensor at nonmal 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 40-way connector terminal 26 and the sensor harness connector.
- If the resistance is greater than 1 ohm, repair the wire harness as necessary.
