Engine shuts donw and "Fail Safe" message is displayed.


first thing you should do is have it plugged into a scanner to see what the problem is.places like auto zone and advance auto parts do it for free. then if it is the throttle position sensor its located on top of the engine not hard to do.but if its one of the four oxygen located on the exhaust sensors depends which one it is but usually requires special socket to remove them without stripping them, very hard.

Enigine fail safe mode


I encountered the same problem, my engine fail safe mode light came on and shut the car down. I took my car to my mechanic and he found the solution to the problem. The car needed a throttle body cleaning and the fuel filter needed to be replaced. After having my truck serviced my mileage increased from 14.6 mpg to 15.4 mpg
ENGINE FAILED SAFE MODE WARNING LIGHT, GONE Total cost $86.45
