When the PCM interprets a value that is outside of the normal specifications for a given component, the check engine light will illuminate and a diagnostic fault code will be stored. You should be able to do these checks by yourself if you read the ATS lessons given to you but I would concentrate your effort to check if the voltage reading of the oxygen sensor is not stuck (this will show that the sensor is defective).Ī bad running oxygen sensor can disrupt your fuel mixture and would cause hesitation and loss of power.

Is this problem serious? Can I fix this myself?įirst and foremost, check first if you have a vacuum leak which can cause your engine to run lean.

I checked wires, connector and hit and reset the inertia switch, we'll see, but I was wondering if anyone had thoughts on or noticed the Check Engine light thing - does it relate to the inertia switch or something else? Seems to me a crapping out relay would just stop fuel flow not shut down electrical. NOTE - I have NEVER have had it quit once it's running.
