1. Disconnect the fused jumper from the ECT sensor connector.
2. Disconnect the IP cluster assembly connector C1.
3. Connect the J 39200 DMM from the IP cluster assembly connector C1 terminal 6 to the sensor connector cavity 2.
4. Measure the resistance.

Is the resistance greater than the specified value?

2.0 ohms
