Question about 2002 Jeep Grand Cherokee

1 Answer

I have a 2002 Jeep Grand Cherokee and I was turning right from a stoplight when the engine died. There was no sputtering just a sudden loss of the engine, power steering and power brakes. I coasted to a stop and turned the ignition off and was able to start the engine. The radio which was playing never quit.

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

My 98 Jeep Grand Cherokee had the same problem. Over heated when standing still. Took it to dealer and they could not find any problem with cooling fan. After doing my own investigation I found out that the electric cooling fan would begin to seize up after about 1hr. of operating. (gets hot)

The dealer would look at fan and see that it was running and think its ok. The problem is, it wasn't running fast enough.

I have a relay on the right side of front fender and jumped the fan to stay on with motor off. (must know what your doing). After about 1hr. fan started slowing way down. Returned it to dealer told them what the problem was. They were not smart enough to jump the relay so they put a couple hundred miles on it even though i told them it works OK when moving. Make sure you tell dealer to use the relay to jump.
Replace cooling fan motor. Works great

Replace the fan relay switch. The dealer will charge you 400 to pull the bumper off, or you can buy the part for 45 and cut the hole in the plastic near the passenger headlight assembly and replace it yourself. There are instructions for this procedure on the web somewhere. I have had this problem more than once with my 02 GC V6.

Your PCM (engine computer) senses a fault code with an engine management component. You will need a codes reader to retrieve the code. If you you do not have a code reader, go to a well supplied auto supply store like autozone, and they will read the codes and let you know what they are. This would be the first step any Tech would do before diagnostic testing begins.

1998 jeep cherokee runs but dies at stoplight but starts back up doesn't do it often


I had the same thing happen to my Jeep Cherokee. For me the answer was that I had disconnected the air filter to work on the power steering pump and I forgot to reconnect it. When I did, the stalling at stoplights went away.

2002 jeep grand cherokee with 4.0 engine will die but restart


I do not know what the error codes mean but know that When I has the sme problem with my jeep it was the fuel pump. What happens is when it heats up it es less and less fuel and chokes the engine. When cold it runs better. remember gas in the tank helps cool the pump but sounds like your pump needs replacing as it is starting to give out.
