If it cranks over but doesn't start, then it's not your starter. code 12 is a common code but code 55 is some type of sensor. You need to call autozone or advance auto and find out what the code is. It could also be an ecm fuse. Might want to check that. Electronics are touchy and tricky topic. Start with the basics. No immediate remedy over the computer/internet. Just me giving you you advice that may or may not work. How many miles on vehicle?

SOURCE: Jeep Grand Cherokee Limited P0700 diagnostic problem

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

SOURCE: 2002 jeep grand cherokee with 4.0 engine will die but restart

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

I need help with a code 12 for. 95 grand Cherokee orvis 5.2l. In need of some help. I know what the code says, but don't understand what it means.


A code 12 just means that memory to the controller has been cleared within 50-100 engine starts, which can occur whenever the battery terminals are disconnected, battery completely dies, etc. Nothing to worry about really, and it is NOT related to the thread that you found.
http://www.jeepforum.com/forum/f11/jeep-cherokee-help-error-code-12-a-1172243/

The codes you found indicate there are no stored trouble codes: Code 12 means that the battery or the computer power lead was disconnected sometime during the last 50 operating cycles. This is not an indication of a problem. Code 55 means that there are no other stored codes in the computer.

Engine code 95 jeep grand cherokee lerado


12 is a battery disconnect within the last 50 start cycles and 55 means the end of the diagnostic cycle.  Basically the computer found nothing wrong. The 12 code may seem incorrect if you haven't disconnected the battery recently, but from my experience the 12 code shows up almost all the time regardless.
