    Servive Engine Soon light came on after oil...

    change. i forgot to re-connect the TPS sensor. The EML also came on but turned off after I reconnect the TPS sensor and re-start the car; but the Service Engine light stayed on. Anybody know how to reset? do I need to take it the dealer? Any damages to the car?

    Please help. Did a search in this forum. Found that a lot of people have this same problem; but did not see how to fix.

    me too (sort of)

    I didn't disconnect anything during my oil change 100 miles/8 days ago. Sunday morning my service engine light was on when I started the oil. The car's running fine.

    I had a Nissan what would turn on the service engine light randomly every few months. It was an emissions fault code, EGR valve as I recall. The dealer reset it, and said that it was a common problem with my model. It would then be fine for several more months. My solution eventually became disconnecting the battery in the car for 24 hours, long enough to wipe the fault code memory (and radio station settings).

    My car's pretty much a weekend/vacation car, so I have some time to decide if I'm going to get the code read or do the unplug for 24 hours thing. If it's a random, erronous fault it will not come back after the unplug thing. If there's really something wrong, the code will come back.

    I did the same thing. I was able to clear the fault using the oil/service reset function. I think I had to do it a couple of times.

    happy to say the light goes off this AM. I guess have to wait a few starts for the computer to reset.

    OBDII scanner tools rule

    I had a code P0128, termostat. My water temp guage sometimes reads a little low. The car is eight years old and had 78k miles. I reset it. I have about 5k miles before the next inspection, and coolant change. Maybe I'll be good until then. I live in Florida, so it doesn't get that cold down here.

    I had to convince Bubba down at the hobby shop that his OBDII tool could read a BMW, though.
