Coolant Temperature Sender: Testing and Inspection
Coolant Temperature Gauge Sender Location
1. Disconnect the YEL/GRN wire from the sender.
2. With the engine cold, use an ohmmeter to measure resistance between the positive terminal and the engine (ground).
3. Check the temperature of the coolant.
4. Run the engine and measure the change in resistance with the engine at operating temperature (cooling fan comes on).
Temperature:
56°C (133°F)
85°C (185°F)-
["C" mark]
100°C (212°F)
Resistance:
142 Ohms
49-32 Ohms
5. If obtained readings are substantially different from specifications above, replace the gauge sender.
