RAM 2500 Van V8-5.9L VIN Z (1997)
Sensor Resistance (OHMS) - Coolant Temperature Sensor/Intake Air Temperature Sensor
4. Test the resistance of the sensor with a high input impedance (digital) volt-ohmmeter.
-
The resistance (as measured across the sensor terminals) should be as shown in the chart.
-
Replace the sensor if it is not within the range of resistance specified in the chart.
5. Test continuity of the wire harness between the JTEC wire harness connector and the coolant sensor connector terminals.
-
Refer to Diagrams/connector Views.
-
Repair the wire harness if an open circuit is indicated.
6. After tests are completed, connect electrical connector to sensor.
-
The sensor connector is symmetrical (not indexed).
-
It can be installed to the sensor in either direction.
