So i bought a 2002 Sahara with 80,000 miles about 2 months ago. incredible shape.
well as i was driving to work (1hr) all is absolutely normal i noticed the sentry key symbol came on my dash. it didn't bother me to much because i purchased a Wolly World replacement key last month and have been using it since. i just figured it is a garbage key and just needs to be reprogrammed. anyway shortly after that light came on i noticed the airbag light would come on for a sec and then go away... hmmmm right? Sooooooo the icing on the cake is about 1 mile from my destination at a stop light, the jeep starts to jump, buck, sputter, ping, backfire, and finally stall.
fml. i manage to restart it and drives fine for about a minute then starts acting up again.then after restarting it, it ran for ten minutes without a problem. i have been doing some research and have come across two possiblities, 1st being the camshaft positioning sensor and 2nd being the crankshaft positioning sensor. but i am having second guesses because of the other two lights.. (airbag and key).
any help will be greatly appreciated.
1- sentry key fault light.
2-airbag light flashes a few times over ten minutes
3-stalling, backfire, buck, piing, revving, sputtering.
i did manage to pull the codes...
P1391 Intermittent loss of CMP or CKP
P1492 Ambient/ Battery Temp sensor input voltage too high
and finally i work offshore so i will not be able to put my hands on the jeep for another 12 days. just trying to brainstorm before i get back and try to make it back home.
thanks again guys.
