One is the cam sensor, which I suspect is your problem, I hope you get this fixed as I would like to see what they find. I have replaced BOTH the crank and the camshaft sensors on my 97. The kat still skips every now and then. I haven't replaced the TPS as of yet. I will try and order one from the dealer on Monday. Maybe NAPA carries them. Hopefully that will take care of the problem. If not...the only thing left to replace is the ECM.

It's very annoying. Have you replaced your fuel pump? I have replaced my tps twice. It didn't help.

Before I decide to chase after the fuel pump or ECM...I will let my Chrysler dealer hook it up to their analyzer. I don't want to keep dumping money into this kat.

Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-02-2014 02:30 PM Update! As reported before, diagnosed as O2 sensors due to running rich. Four sensors were bought and the two upstream were fitted. We couldn't fit the rea two due to several reasons, time and place. Car was tested but still fluffed a little but not fully cut. The next day car went faultless. Next day cut out four times in a row before the temp gauge read normal. Fast forward to today. Rear O2 sensors came out fine, new ones fitted. Car hooked up to machine. Great news is that all sensors are now showing values within parameters.( all along one sensor wasn't happy so thought lets change them all). Other great news now is that two seperate codes have been set. First is p28 crank sensor and p2c auto shut down relay to TCM. So I believe we are now getting somewhere. phew. I shall order the sensor and report in due course.

Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-02-2014 03:53 PM News, all four O2 sensors now fitted. When check out first time around it appeared one sensor was not right. Bought four new ones and are now fitted. Car started and ran fine. Machine hooked up. Two codes come up p28 and p2c. All values for O2 sensors are now in parameters as they should be, so good news. Also good that two codes now up. Will buy relevant parts and keep you updated.
Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-15-2014 04:09 PM News so far. Since fitting four new O2 sensors the car has been cutting out far more frequently. But when on the machine it does now show them all giving values, one was duff prior to fitting new ones. Also two codes came up , one of which was the crank sensor. I had a sensor sent over, thanks Ed, and fitted it today. Now before I fitted the sensor the car would idle fine on the drive and after about ten minutes, simply cut out. After the crank sensor went in I started the car up. It simply didnt cut out at all. I took it for a short drive, with no issues at all. So far so good. Basically my verdict so far, one 02 sensor was faulty and no codes came up. Replaced 02 sensor, car cut and two codes given one being crank sensor. Replaced crank sensor and all appears fine. We will get it on the machine again just to check. Thanks everyone. Oh one last thing. The cutting out steadily got worse and worse over a two year period and after it started stalling I even took it to my dealer. Absolutely no codes were being thrown up. So I guess the 02 sensor was masking the crank sensor?

catfish POA Site Supporter Prowler Junkie From:scottsdale,az,usa Registered: Jun 2001 Admin Use	posted 09-15-2014 04:44 PM the 02 sensor would not mask another sensor. ------------------
Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-17-2014 04:18 PM [QUOTE]Originally posted by catfish: [B]the 02 sensor would not mask another sensor. How do you explain the findings Jan? Basically the only codes that were ever to be thrown up happened after I replaced all the O2 sensors? The car has been on the equipment at a Chrysler dealer and now at an in dependant car place. The only time a suspect O2 sensor was found when hooked up was at the in dependant garage. No codes came up, just the errant reading of an upstream O2. I took the opportunity to replace ALL the O2 sensors for peace of mind. Once these were installed the car the car started to stall/ cut far more frequently and when it did stall wouldn't start straight away, the starter would spin but that is all. You had to sit it out and wait. We then put it on the reader that is when two codes came up. One was crank sensor, the other was related to the shut down relay earth from ECU or what ever you call it. So I have replaced the crank sensor and all now appears to be fine, no cutting whatsoever. It is due to be hooked up again to see where we are on this? So all in all we only found out it was a dodgy crank sensor when the O2 sensors were replaced. Seems odd if the crank sensor was faulty and no codes came up? Any explanation guys?
beachcat BANNED From:Ontario, Canada Registered: Jul 2011 Admin Use	posted 09-17-2014 04:47 PM wouldn't the faulty shut down relay ground be the more likely cause? What did you do to correct that? This message has been edited by beachcat on 09-17-2014 at 04:50 PM
Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-18-2014 10:36 AM In answer to your question Roger, absolutely nothing! I simply replaced the crank sensor and started the car to see what happens. It is due to be looked at further next week. So as ever, I shall keep you all in the loop. I took the car out today, did about 15 miles with simply no cutting out at all.
quincy POA Site Supporter Prowler Junkie From:Fairfield Glade, TN. USA Registered: May 2004 Admin Use	posted 09-18-2014 05:36 PM What a nightmare of a post. 5 pages of chasing electrical issues. I hope changing the sensor cures your ills. For peace of mind I recommend you look up a old post by catfish on critical wiring harness pinch points, and perform the preventative procedures spelled out. It may help.

ed monahan POA Lifetime Site Supporter Prowler Junkie Personal ScrapBook From:Cincinnati, Oh, USA Registered: Jul 2000 Admin Use	posted 09-18-2014 07:31 PM Two posts on THIS thread. Page 1 no relay issues that i know of.wire loom problems yes many.ck complete loom from where it comes out of firewall,possible cut or squashed wire,or wires.in many places wire loom is wire tied to tight against body.cut the old ties loose,ck. loom and retie loosely,a problem with loom will cause many diff.codes and codes that dont exist.ck wires going to computer behind rt side panel also.there in a bind there also. Page2 ck. the loom on drivers side where it runs down the cowl.cut the wire ties loose and visually inspect the loom.you may not see any cuts.a wire does not have to be cut to cause a problem.a squashed wire or wire loom will act the same as a cut one.in many places the loom ties are to tight squashing the loom and wires.cut loose/inspect and retie gently.i would ck the entire frt. loom,it could be squashed anywhere.the two places mentioned are known problem causers,there could be more.if you had a vaccum leak you would most likely hear it.what kind of update are you looking for.a loom is causing the problem or it isnt.if you dont do the above you will never find your problem,just looking at it wont cut it.

Dave Haggas Prowler Junkie From:united kingdom Registered: May 2007 Admin Use	posted 09-19-2014 01:32 AM Did all of the pinch points first. And yes they were tight, but nothing I would view as very bad. All ties were cut, loom lightly warmed and kneeded. Even opened up the protective sheathing to do all this, then re taped up and tied up better. So it now seems all is ok, touch wood, crank sensor was the trouble...

CCJ POA Site Supporter Prowler Junkie From:Little Rock, AR, USA Registered: Jan 2013 Admin Use	posted 09-23-2014 04:41 PM I finally got my car back from Chrysler and they said I also have bad O2 sensors. They say this is why my car cuts out for half a second (posted video earlier in this thread) they also said map sensor is faulty as well. (manifold absolute pressure) Does anyone know the part numbers for the O2 sensors? Are the top bank and lower bank O2's different parts? I only see 4606133AC as the part number for all 4 O2 sensors... Is this right? Does it matter that I have an aftermarket exhaust? If so, should I order O2 simulators? I always thought O2 simulators were for those with headers... I also thought about this: I could possibly just clean them out. Some different methods... 1. Clean it with a throttle body aerosol cleaner which states that it's safe for oxygen sensors. 2. Heat it up with a torch and dip it in water. Use an air hose to clean the gunk out. Repeat. 3. Soak it in gasoline overnight. Shake the dissolved gunk out. I feel like it's one of those things nobody's going to tell you how to clean your bathroom mirror with ammonia at $0.99 a gallon, but lots of people are happy to sell you ammonia with blue die in it at $4.50 a pint.
