In my case, I usually check the oil at the around the same place on road from my house where it’s level and it’s reached the temp (and, now I know some movement) to do so. After adding 1qt when it had indicated to do so with warning light, the sensor read full and I was happy (other than wondering why I was still losing oil after replacing the opg…). A day or two later when I checked the sensor said 1/2 below full and stayed there. That bothered me but I didn’t add any more oil. Overtime it’s gone to 1/4 and sometimes will flash add +1qt. I don’t have concern with +/- 1/4 as I assume that’s the resolution of the sensor output. I have to think the sensor or connector or something is not right when it jumped from full to 1/2 overnight?
That is without anything obvious going on with oiling system, increase in coolant level, puddles under car, smoking, etc.
Regardless when I change the sensor I’ll post if I find anything interesting.
OP, my apologies for hijacking your thread.
