Step 3
Verify sensor element continuity and resistance.
Remove sensor element cable from the bottom of the control circuit assembly. Note that 2 of the wires have a red stripe and are
located closest to the interconnecting cable header. Using an ohm meter verify that resistance between the 2 red striped wires is
approximately 1100 ohms +/- 20. This resistance is temperature dependant. The resistance at 70 degrees F should be 1082 ohms.
Verify the resistance between the 2 natural colored wires are approximately the same.
