Ok, been dealing with a P1078 code (2006 6mt) . Can clear it out and about 30 mins later the CEL lights up again. Had it scanned and its pass side bank one, so pulled it to check function. It was clean and works when power is put to it, but checking the ohm rating with a multimeter shows a consistent 7.5 ohms. Looking online, I find 3 different ohm ranges for “good” on these, 8-12, 7-12 and 5-12. Does anyone know for sure what the correct ohm range is for these?
