Question about 2004 Jeep Grand Cherokee

1 Answer

I have a 2004 Grand Cherokee and the engine was cutting out and coming back when driving., the gauges were all going crazy. No check engine lights came on on the dash. Had to have it towed and the mechanic couldn't get it to do this then it did, but still no codes. He then took it to a Jeep dealer and they can't find anything so they are giving it back to me. Like I want something I know is going to screw up again. About 2 months ago we had a simliar problem and they replaced the crankshaft sensor. Any ideas??

    I have a 2004 JGC that began lurching and guages bouncing all over the place only at high speeds of 60 or more about 3 months ago. Initally the dealer replaced a deteriorated battery cable, reset the computer, and put in new voltage sensors. Problem came back, They then replaced the PCM (luckily under the emissions warranty,) Problem came back and now the truck dies after going a few miles. Dealer has now had it 3 weeks and still can't figure out the problem also they are not getting any help from Jeep manufacturer. Dealer has since put in a new battery, new transmission sensor and still can't get it to go for more than a few miles without dying. Each time it quits it wipes the computer clean. All in all I have almost $2K into chasing this problem. So far the dealer is not charging me for diagnostics only parts. But still the trade in on this thing is only $6K or so.

Intermittent problems like this can be caused by so many different things. However, if it happened before and someone traced it to the crank sensor. It probably wasn't the crank sensor, there is likely a bad connection, or a short in the circuit for the crank sensor.

My Jeep won't start. I replaced the battery but the car will not start. The gauges all go crazy and I hear a ticking noise, but it seem there is no power getting to the engine.

Does the engine turn over at least? The gauges getting crazy points to a PCI data bus problem, then also the engine will crank, but not start. Could be one of the components connected to the bus. Also common is water ingress in a large connector on passenger side bulkhead, which causes the data bus to short out..

My 2004 Jeep Grand Cherokee intermitently misses, the gauges go crazy and bounce around. No check engine light comes on. I had it checked for codes anyway, all passed. I changed the plugs, same results....

sounds like a ground problem. Or a short. I would get a helper and have them sit in truck and watch gauges and things and i would get under the hood and wiggle every wire i could untill i found the loose one.

I have a 96' Grand Cherokee Laredo . while im driving my gauges will shut off and my windows freeze up. and my doors will relock and everything will come back on. what could the problem be?

May sound crazy but have the alternator checked, when it fails it will shut off the gauges and make all of the electronic equipment act strange. I had a cherokee that did this to the gauges but that was b/c it was full of mud from my previous trip.

2004 Jeep Grand Cherokee. Keeps stalling, engine

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

Difference between oil sending unit and the oil pressure switch

Same part...make sure you get one for gauge, not idiot light though. If the engine has any knocking or ticking when pressure drops do not drive it and have a mechanical gauge installed to check actual pressure. Parts often have different names for same item...your driveshaft is actually called a propeller shaft!!!
