SOURCE: 1999 4.0L Jeep Grand Cherokee shuts down after 20-30 minutes.

I'd suggest the ignition control module, however I'd have a certified mechanic check it out just in case...

SOURCE: Normal coolant temp for 2003 Jeep Grand Cherokee city/highway V6

U should have the accuracy of the gauge tested before u spend any more money on this, factory gauges are not very accurate. U are still in the normal zone though no matter what the other expert says, and jeep Cherokee's run hotter than 195 due to how small the engine bay is, my friend and fellow tech works for a jeep dealer and says hot running on V6's and overheating esp on the V8's is a common issue even on new trucks.

SOURCE: Turn signal doesn't always work Jeep Grand Cherokee 2003

Had same problem with 2003 JGCL, found problem in turn signal relay. You will not like digging for it, because you will have to remove two peices of dash board, peice below instrument panel and knee board (2 bolts on bottom and 2 screws on top). The relay is the long cube, top center above the main fuse box.

p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

I have a 2001 jeep grand cherokee and it giving me four code p1391 p0351 p0352 p0353 i will like to know the problem please


For some reason you question has been duplicated several times, so I will answer this one.
Code 1391 may be a problem with the ABS system, the other three codes are concerning the first 3 coils. Your engine has direct spark so each cylinder has its own coil.
I would clear the codes and see which ones come back after a test drive. If the three coil codes come back the coils would need to be tested.

JEEP CODES P1391 AND P1398


p1391= crankshaft / camshaft position sensor intermitant signal, check, wiring, connections & sensors
p1398= engine control system missfire detection limit reached probable causes, wiring,poor connections,engine mechanical fault,ignition/fuel system fault (causing misfire) or camshaft/ crank shaft position sensor

P0320 & P1391 OBD codes displayed, found during emissions testing but there are NO engine or driving problems idicated.


P 0320 = No Crank Reference Signal to PCM. No Crank (shaft position) reference signal detected during engine cranking (starting).
P 1391 =Intermittent Loss of either Camshaft Position Sensor or Crankshaft Position Sensor.
Hav you attemtped the "3-Key-Ons" method to see these codes on your digital Odometer (assuming you have one) Turn the Key from Off to On (not start) three (3) times. On the third (3rd) time leave the Key in the "On" position (not start). Look at your Dogotal Odometer (if so equipped). The Codes, one at a time should appear. The Last Code will be "P donE".
If te engine is performing without problems: disconnect the negative side of the Battery and wait at least 5 to 30 minutes. Reconnect the Battery. Re-preform the 3-Key-On's and see if and Codes are now showing.
If you start having Start or Running problems becoming more and more frequent: consider replacing the Crankshaft Position Sensor. If this sensor "fails" you may not get any fire to anything, as this is the signal that is necessary for the PCM to initiate the Firing Sequence. The PCM will not send a signal to even the Ignition Coil to begin.

I have a 1999 jeep grand Cherokee larado V6.


The P1391 code indicates that the crank or cam sensor(s) have sent an intermitant code to the ecm. The most common cause for this is loose wiring or debris on the contacts of one of the sensors.

I have a 2001 Jeep Grand Cherokee and my check engine light is on. Took it to "Advance Auto Parts" and got the code P1391. What is this?


could be a crank or cam sensor beginning to fail, or a bad harness connection at either. Usually though you would feel a problem there as both are necessary to keep the engine running.

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.
