That was one of the things that was on the tank off list. It was weeping, so I pulled it, cleaned it, and put some hi temp silicone around the o ring and reinstalled it. I know they are fragile, and maybe a wire broke, but the test at the computer plug looks ok. 703 ohms instead of 680 sounds ok to me.
Would checking the resistance of the coil tell you if the sensor is reading correct? Like if the gap is incorrect.
I ask because I’m curious, not trying to be facetious. Also not trying to rhyme...
