i have a problem with my check engine light i can't get it to turn off i'm getting a p1391 code so i've changed the cam sensor, crank sensor, coil, plugs, plug wires, cap, and a rotor and the code just won't go away and i've had the code cleared with a code reader any help would be much appreciated

 

remove neg. battery cable.. turn the key to START and hold for 45 seconds.. reconnect the batery.. see if tat does anything..

this resets the PCM .. takes about 200 miles to relearn everything..


btw.. when you post could you please put ... better yet in your signiture, information about your truck.. helps out alot when we try and help!

 

so what happens durnig these 200 miles while your truck relearns everything

 

when i reset the computer it will go off and stay off the first time i drive it but if i stop and turn the truck off when i start it again the light comes back

 

sorry about not having info on my truck its there now

 

well you might have another problem somewhere. We cant fix it for you. so look at all your options and narrow it down. think outside of the box. good luck, sometimes its hard to get rid of the Dreaded Cel. If you cant fix it, go to a stealership and see what they say

 

I had this same prob. Did everything that is being sugggested that you try. I took mine to the dodge dealership. After they replaced the seal (where you put gas in) and reset, the light came back on. Took it back in and they replaced the gas cap, the light came back on. Took back for the third time and they foundthat the probwas the vacuum hose, the light was reset and never came back on. Hope this infohelps.

 

do you remember what vacum line they replaced if so where was it

 

Not sure. But, I can find out and let you know. I will call the service dept 2 mar o. They should be able to tell me.

 

man that would b a big help i would appreciate it
