About 2 months ago I got the reading. My defouler was good for about 2 months before the light came on. I have a Strupp race header.

We went and took the defouler off that came on the header and bought a 2 pack of spark-plug defoulers. Drilled a hole through one of them so the sensor would fit, screwed it on the back of the other, screwed it into the header and put the sensor back on.

I know it sounds cheap but it does work.

I doubt your sensor is bad.
