I just bought this SUV, it has one previous owner (older lady who had it serviced every 6 months) This SUV has been babied, to say the least. I was driving down the highway when I noticed that the "check engine" light was on, I had my dad check everything on the engine earlier that day, and everything was fine. I was hoping that the light would go off the next day, but it didn't. The truck still runs perfect, lots of power, not reving high, and sounds great. I read the owners manual and all it says is "take it in to your dealer" I can't afford that right now. My dad thinks that it might just be a sensor but if anyone knows anything about this or has had this happen to them could you please let me know! thank you soooo much!

Turn the key to the ON Position, then OFF, then ON, then OFF, then ON - leave it in the ON position this time.
The CHECK ENGINE LIGHT will begin to flash the codes, they will flash in double digit form with a SHORT pause between digits and a LONG pause between codes.
example:
flash pause flash flash - 1 pause 2 = 12
pause pause pause
flash flash flash flash flash pause flash flash flash flash flash - 5 pause 5 = 55

Code 12 - Battery was disconnected within the last 50 ignition cycles.
Code 55 - End of fault codes.

On vehicle equipped with digital odometer the code will appear in the odometer (example: P0622)
