XJS Coolant Temperature Sensor Test
- Disconnect battery ground cable. Remove connector from temperature sensor. Connect an ohmmeter between sensor terminals. Resistance should be as specified. Refer to the XJS COOLANT TEMPERATURE SENSOR RESISTANCE table in this article.
- Check resistance between each of sensor terminals and sensor case. High or infinite resistance should be present. Connect sensor connector and negative battery cable.
