Step 3
Verify sensor element continuity and resistance.
Remove sensor element cable from the bottom of the control circuit assembly. Note that two of the wires have a red stripe and are

located closest to the interconnecting cable header. Using an ohmmeter verify that resistance between the 2 red striped wires is approx-

imately 1100 ohms

±

20 ohms. This resistance is temperature dependent. The resistance at 70 degrees F is about 1082 ohms. Verify the

resistance between the 2 natural colored wires are approximately the same.
