i have a 1996 Infiniti I30 and my check engine light came on a couple days ago. i got my car scanned and they gave me the code: PO125. what does that code mean, what do i have to do to fix it? is it going to be expensive? thanks.
If your car is running good you can undo the battery for a few hours it should reset the sensor. Some of these lights are programmed by the auto engineers to get you back to the shop. If you have no other problems with the vehicle try re-setting the electronics by safely disconnecting the battery at the negative terminal, wait a few hours in case there is a back up memory for short outages, and see if the light stays off. You'll have to reset your clock, and presets, but the light may go off and stay off with no adverse affect to your vehicle.
