A p0303 is a cylinder number 3 misfire, which means that the computer is reading that the number three cylinder of the engine isn't contributing as much power as the others. usually is just a tune-up issue, i would suggest checking or replacing tune-up components. that will usually handle it.

Hi:
There are hundreds of things that can trip the check engine light, some so simple as a loose gas cap. Your best bet is to get your jeep scanned for free at a local auto parts store, such as autozone. Usually they will scan your code, and tell you what the most likely cause of the code is. Then you can make a good decision as to what needs fixed!

Check Engine Light illuminated


The most likely problem is the crank sensor , as far as check eng light find out what code it is that might help. Codes on little code readers are sometimes just a general discripition that could even lead you in the wrong direction. most of the time the fuel system does not trip the light. so rule that out for your question, not to many sensors will stop the motor that leaves the crank sensor which is a jeep night mare they always go out. it will be located in the top of the bell housing where the eng and trans go together. on the 6 cyl you can most of the time lean over the engine and see it. it will have one small bolt holding it in and then the little wire harness to unplug.

Put the key in the ignition and turn it on and off (3) times without starting the jeep, leaving it in the on position count the (1) flashing indicator Light, Eg: (5) flashes, Then there will be a pause, then it may flash (3) times, this is a code #53. Keep your Eye on them and write them down. If you should miss (1) Repeat as many times as needed, Info: A #55 means there are no codes!!
