getting ODB codes p0455 & p0442

i purchase a 2002 jeep grand cherokee, it did not come with a key fob or original key. So when i go to unlock the door with the after market key that i have, the horn will honk until i get in and start the Jeep. My question is, can i get a key fob and key from a local junk yard and have it reprogramed to work on my jeep?

had an o with the ceiling know it is bad

Engine leaks front of engine and by the firewall how much to replace rear main seal, how long to fix it. Put in "lucas stop engine leak" and 3-4 qts oil every 6-8 weeks.

The switch that controls direction of heat doesn't work. Only blows out front vents . Windshield fogs up on inside. Can drive for an hour on defrost & is fine. When sitting at idle, will blow cold and fog up. What needs to be replaced?

Also uses a lot of gas 13 miles to gal

Any suggestion for what might be causing problem ?

My 2001 Jeep Grand Cherokee runs great. But when the outside temp is 65-70 degrees and driving at 55mph or greater and hit a small bump like a seem in the pavement or a pothole, etc... it will hesitate sputter for a few seconds. I have tried a tune-up, shocks, sway bar, steering damper, ABS, brake pads, brake calipers, throttle sensor. No luck so far.

anytime the heat or airs on

1. After remote start, engine shuts off.

2. error code p0481?

rpm and speedometer plus headlight flick on and off and other gauges comeon and off ..rpm and speed rev up and down

engine was running fine, shut it off for few minutes when i restarted it #2 cyl was dead. also affects #1 but compression is good there

O have no working wireless remote to my car until the one I order arrives. But Ive been having a issue with when I unlocked the doors of the truck after locking it the horn and singnals start to light and the horn blows. What could be wrong? Also my 6 changer cd player keeps flashing eryor and wont allow the disk to eject or play now.

my fuel pump was bad, replaced it, lasted 2 weeks then did the same thing again. then when trying to styart it was spitting out codes, so then I replaced the the main computor, two diff. sensors, new spark plugs. still wont start!

I've changed steering column and I was told by lock Smith that the key and skim in the column I installed doesn't match my computer so it can't be reprogrammed I've already spent a lot so wats easiest way to fix problem?

Can I turn off the "Automatic Mode" to avoid turning it off every engine start?

How much should a transfer case cost?? I believe, I payed too much. I payed $600 for the part and $300 for the labor for a, total of $900.

the owners Manuel states do not use power washers over 1200psi & I have no idea what the psi is at the auto car washes. Also a concern about it coming out of neutral when being pulled thru the car wash??? I am just a stupid concerned lady any advice would be appreciated. Thank you

Hey all.

I noticed that when I remote start my Jeep Grand Cherokee, it smells like gas is coming from the exhaust.

Is there a way to diagnose what is causing this and to fix it? There is no check engine light and no codes according to my OBDII reader.


I have removed it from the differential but the axle runs through the strut or shock mount - plz help soon lol

Would like to know the labor rate to pull a long block engine and swap it with a short block crate motor in the 29621 zip code. Engine is the 4 liter inline 6 cylinder

I think it's over heating, IDK.
