Check Engine Light Help?

My check engine light has came on my 1998 jeep cherokee with a 4.0L so I pulled the codes and it brought up a code here it is


P0320 Ignition/Distributor Engine Speed Input Circuit



Does anybody know what this code is and can it cause it my jeep to overheat?

I'm not a jeep expert, but that code indicates a loss of signal from either your crankshaft or camshaft position sensor. It needs to be followed up by the pinpoint test that will check the circuit and the sensors involved in that subsystem. Most late model cars use both sensors to keep the rpm info to the pcm. If one sensor fails the other will tell the pcm the engine rpm.

DUDE! You've asked this same question like twenty times in the last month. Buy a repair manual and fix it or take the stupid Jeep to a garage and let them fix it. With the time wasted to come on here and ask twenty times what the same code means you could have bought a manual from the auto parts store and fixed the car by now.

YO TONY,I not really a Jeep tech. either.But I am familiar with them, that is I have worked on a few. and I know something about O.B.D. II '.Since the code description mention "dist. ckt." and assuming the dist. is driven off the cam,
(I don't "think" it does in a 4.0, but really can't remember..call it a brain fart) then it's more likely the cam sensor.It's been my experiance the "crank" sensor is usaully the one that fails,so look at the dist.
located on the passenger side of the engine,I think see if you can determine if the dist.shaft extends down toward the crank or if it sits "above" the cam,obviously if it's above the cam,it's twisted by the cam. you can also check pulse generator patterns if you have a high impedence multimeter, But I have seen those test give enough inadaquet readings on these jeeps,I don't trust them,so I usaully end up sticking a "test" sensor in to double check anyway.The crank sensor sits in the bell between the block & firewall,so once you get one in,since it's your vehicle,leave it in.(you'll see why.)
Now the ECM relies on info. from those 2 sensors to calculate and adjust timing (ign./inj.)and fuel rate, so It would be possible your overheating problem is related to this. You may also want to check wiring connections,like where the engine harness ties into the main harness,pull the connectors and do all that pain in the a-- inspecting,I've seen plenty of qualified techs. beat their heads against the wall due to chry/jeep connectors lemme' know how it turns out, ok...
