Coolant Temperature Sensor

ECT Sensor:

- Disconnect coolant sensor connector and measure resistance across sensor terminals.
- Resistance should be within the ranges on the table. Replace a sensor that deviates from these readings:

ECT SPECIFICATIONS
Temperature °C (°F) Resistance (K ohms)
-10 (14) 7 - 12
10 (50) 3 - 5
20 (68) 2 - 3
50 (122) 0.7 - 1
80 (176) 0.2 - 0.4
