SOURCE: Trouble code 52 on Jeep Grand Cherokee Limited 5.2L?.

the tps could cause the pcm to think the throttle is open further than it really is, adjusting injector pulsewidth to compensate. but. the 02 would see the rich condition, the idle would suffer and the idle air controller would open to compensate. all technical discussion aside, you need to check the 02 sensors output voltage while running. backprobe the output and make sure you're not getting over 1 volt and that it dances from about 200mV to 800mV at a high enough rate that your DVOM has a hard time keeping up with it. If you get a steady voltage, chances are the 02 sensor is shorted inside to either the ref. B+ or the heater B+. If it's not switching and the voltage is high, unplug it and check for voltage in the signal wire of the harness. could be a wiring issue before the 02 as well.

SOURCE: 2005 jeep grand cherokee limited 5.7 hemi vehicles hesitates

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.

SOURCE: crankshaft sensor located 98 jeep grnd cher 4wd 6cy

it is located at the back of the engine on top of the transmission bell housing,the plug runs over to the passenger side of the engine bay and it comes out from behind the engine,you can actually get your hand on the sensor itself from under the hood on the drivers side,and i believe its a 13mm bolt holding it in,the new sensor will have a sticker on the end of it...leave it there,it is used for correct spacing between the sensor and the flywheel,hope this helps

2000 Grand Cherokee Limited, the car runs well but sometimes when i stop it refuses to fire.The engine turns over well and i have gsat the injectors but it wll not fire. Have changed plugs but to no avail,...


Jeeps have a reputation for the crankshaft position sensor going out. The sensor "counts off the rotation of the crank" if it fails to read the mark that makes the sensor, it will stall and re-start. After a while it will no longer start. I had a jeep with this problem, and it would shut down going down the interstate, but restarts. You can replace the part, it's about $60 and located at the back/bottom part of engine.

1998 grand cherokee limited crankshaft crack?


To identify the crankshaft, with the belt removed, it is the only item that will turn when you crank the engine over.
I've seen harmonic balancers fail but rarely a crankshaft.
Some P/S systems will "push" some fluid out when you steer without the pump running. Concentrate on repairing/replacing the balancer, then re-diagnose the P/S problem after that is taken care of.

on this engine the most common problem is the crankshaft poistion sensor (CKP sensor), it will set a fault code in the computers memory, so have a local autozone or kragen test the system for the crank sensor code.
