Thanks, that's a really helpful picture! Is that image from a larger set of pictures? The directions I got for my sensor weren't this good at all.

It probably has an internal problem where it doesn't process one of the inputs. I've seen it many times. To be certain before concluding this are you getting around 1.35V at both potentiometers as I described above? I didn't measure them before. Could you educate me on how to measure the potentiome...

If the unit starts up properly with ignition in PosII by clicking once then singing for 6-10secs then clicking back off then the voltage is fine; no calibration needed. Because you've scanned with a generic scanner you've probably missed that it was a signal missing from one of the two sensors. Old...

Hey all, I have a 2000 S80 T6. Last week I pulled code P0121 from it after it went into limp mode. It has a check engine light on, service light, and a message that says engine service needed.
