I'm not quite sure what you're talking about--
You don't have an "IDIOT" light for low oil pressure, there is a little spigot (drip) --(upper middle left) and it comes ON when ign is on, then goes off--
If it stays on, it doesn't matter if your oil level is full--you shouldn't driveit--AT ALL-
The only other light that has anything to do with oil, is the "Chg oil lite"-
Which one are you talking about ??
Your tire pressure lite (TPMS) is an Ancient Chinese system that only SAMURAI warriors or the AEV Procal Module can fix--it's an OBworthless system!
