Temperature Sensor Check

  1. Remove water temperature sensor. Water temperature sensor is located on top left rear side of engine. Place water temperature sensor in container of water, and heat to 176 F° (80 C°).
  2. Using an ohmmeter, measure resistance between case and terminal of water temperature sensor. If ohmmeter reads between 49-58 ohms resistance, temperature sensor is okay. Check cooling system, and repair as necessary. If resistance is not 49-58 ohms, replace coolant temperature sensor.
