Nada... It was going off today in traffic again
Anybody check their battery voltage? Mine seems to be a little low. Starts at 14+. Then as the car warms up, and I'm using the AC, it drops to +/- 13. I really need to get off my ass, and check those grounds before I waste $$$ on a new battery.
Keep you guys posted.
Sensor is a 3 wire connector, passenger (right) side oil pan.
If electrical loads seem to change the reading then it could be a grounding issue.
I have read a TSB on redoing the ground but have never done one.
Hmmm, can TSBs be done out of warranty?
I seem to be having charging issues, and a new battery didn't help. So I decided to check the grounds. Did the one on the fender first. Maggie guys should really check this (except Randy). Took off the bolt, and wire brushed everything. Did one behind the drivers side head, but could not get so much as a finger behind the other head. Then I got under the car to check the starter wires. Took one wire off. It was pretty bad, but I cleaned it up best I could.
Plugged the sensor in, and drove to work this morning. It was a cool morning, and a short ride. But I had everything on, A/C, lights etc. Oil temps moved around between 210 and low 220s.
I'll update after I've been on a longer ride.
Unfortunately, car is still showing low to mid 13v
If you remove the windshield wiper facia (very easy) you can get at the rear of the heads much easier.
The passenger side is less of a problem if you remove the battery.
