Question about 1996 Jeep Grand Cherokee

O-2 Sensors on a 1996 Jeep V-8


I went to the library this evening and using Chilton Repair mauals, it stated that Chrysler engines manufactured after 1995 required at least 4 oxygen sensors: two on each bank, (named after the first cylinder firing order), another one in the exhaust pipe (in front of the catalytic converter) and the fourth, on the downstream flow, after it.

So, if your answer is correct..that there are only two... then you are telling me that Chrysler did not manufacture the 5.2 L V-8 engine in my Jeep.

Is that true?

Best regards

**** Owan is my e dress

PS: Thanks for your help. I don't know what to do now after I replaced that sensor (located underneath the chassis) and in the exhaust system, and still have the MIL light come on after the engine reaches operating temperatures. My Code Reader still insists it is a problem with a bank 1 O-2.

    I bought a Bosch, and took it back for credit. The new Mopar sensor didn't work either, so I'm looking for some other related issue.

    Archie said that after further anlysis, his mechanic was taking ohm readings on the socket---with the ignition on!!!

    Apparently he shorted the 12 v line input to either ground, or one of the other leads. The result was that he blew the fuse to that circuit.

    Therefore, we may never know if the Bosch O-2 sensor was bad, but we do know that the Mopar replacement (whether better or not) fixed the problem.

    Thanks for the advice; however, you never did answer our question about who made the 5.2 L V-8 engine for our '96 Jeep Grand Cherokee.

    If it was Chrysler, why didn't they use the same method of installing 4 O-2 sensors, one on each manifold bank, one upstream before the Catalytic C, and the last one downstream after it, like they did for ALL Chrysler V-8 cars produced after 1995"

It is possible in some states.

Re: 1996 jeep cherokee need fluid capacities air filer # oil filter #

Anywhere you buy those parts, they will have a book that lists those numbers (some vary from manufacturer to manufacturer. You will need to tell them the year and engine size though or they can't help you. Off hand, most 6cyl 4.0 engines use 6quarts of oil and filter is usually a #16.(for oil). You can also buy an inexpensive manual like chilton or haynes that will list lots of things you may need to know.

In removing harmonic balance on 1996 chrysler concorde 3.3 engine, my chilton repair book states to use a 4" 3 arm puller and a special tool to place in the center of the pulley, I'm have a problem...

Hello, This is also called a gear puller. The best place to find them is at a tool store like sears, harbor fright Farm & Fleet or Fleet farm. I know harbor fright has them causes that's where I got mine. Harbor fright also has a web site online. If you have any more questions feel free to ask me. Good luck

Check Engine light- catalytic converter

It might be helpfull to know the codes of the "check engine"lite but it seems the PCM is the issue,be sure the O2 sensors were the correct ones and which dealer made the recall? an used-car one or a Chrysler one?if no solution,you should go to a chrysler/jeep dealer and talk to solve this because it is a recall involved and they should repair your SUV at no cost no matter the miles on the odo!.buena suerte!
