Rev counter not working - Jeep Cherokee

I guess I'd ignore this if I hadn't noticed today after getting the "check engine" light come on yesterday. Trouble code 32 55 which I understand thanks to an answer I had earlier, but now the rev counter as well? Is my Jeep going senile on me?

    I appreciate that the trouble code and the check engine light should have nothing to do with the RPM guage, but it seems a little suspicious to me that both problems have come within 24 hours. The Cherokee is a 2.5 TD limited 1994.
    The other thing worth mentioning I suppose is that otherwise it is running very sweetly indeed: starts first time every time; stays at very steady temperature; oil pressure seems very steady etc etc.
    Any advice would be helpful although I appreciate that my next step is to buy a Haynes manual and try to address the first error code 32.

    buy a factory manual, the Haynes books are not up to the task of emission repair diagnostics

    that is not a code.The check engine light has nothing to do with the tachometer operation unless there is a miss then it may jump around from the RFsignal generated by the misfire.

Take it to any Autozone or Advance Auto. They will check it for free! Probably other similar stores will do the same!

Don't know much about VW but if it's fine, and it doesn't happen again I wouldn't worry about it. If it does try resetting the ECU by removing the battery terminals and touching the positive lead(red wire) to the negative battery post. It might spark a little, this is just the capacitors discharging, resetting your ECU and starting over. It's like restarting your personal computer

SOURCE: rev counter, speedo & sometimes fuel & temp guage not working

pull the instrument cluster out and check the printed circuit and connector to it from harness, plug it in and out three or four times, this may cure the problem.

While driving my jeep seems to be shifting gears the rpms rev up and then goes back down almost as if surging I changed speed sensor as a guess so far but did not work?


old 1995
we need vastly more symptoms then that,sorry
if the engine surges, that is first. (surges in 1 gear)
but if a transmission down shifts that is normal, rpm rises
(after all its a lower gear) (higher numeric ratio)
find any machanic in town
ask him test drive it.!
10 min.later he wilt tell you
its trans issues.
or its engine, super easy this is driving.

seems you can not, and learning is 1hour in car class..or 10x that lacking facts of drive train functions.


stop guessing. why spend cash on a useless sensor now.
spend cash on $1 shop diagnosis and WIN.
i promise !

or get it scanned.
and post all those DTC errors. P0700? and more.

My 2002 Jeep Grand Cherokee makes a clicking noise from dash broad as i decrease in speed. Stops once vehicle has slowed down


Have you checked that the speedo and the rev counter still give steady readings, if you can notice a slight "judder " on either then that is where the noise is coming from. Must be one or the other is speed related.

Hi, I have a '95 2L Legacy Boxer 2 stage twin Turbo. When i'm driving and the engines reving at ot just above 2000 rpm I'm getting a dip in power for a moment before it picks up again. I haven't noticed...


the 1st thing that needs to be done here is to find what fault code is turning on the check engine light, this information is absolutely crucial to making an accurate diagnosis of this problem, guessing is not an option as each part that could cause this is very hard to replace and very expensive, so get the the engine control system tested, this is what is called OBD 1 electronic engine control and requires a Subaru scanner to read code.

I have 1996 jeep cherokee sport 4x4. When I start the engine it makes a squeking noise and gets louder when i step on the gas. I think the belt is starting to slip. I have also noticed when its making this...


Your water pump is starting to seize up. Today's modern serpentine belts don't just slip. Your water pump is dragging. Which is causing the noise and the temperature increase. Get it fixed and you will notice better gas mileage. If you continue to run it like that be sure to keep your eye on the temperature gauge. One overheat or close call has the potential to do big damage to an engine of that age.

1998 GRAND CHEROKEE CLUSTER NOT WORK , WILL LIGHT WITH LIGHTS ON NO IGNITION LIGHTS ONLY ABS INDICTORS WORKING


I would look for a blown fuse first, then look for a loose connector on the harness under the dash,considering the age of the vehicle, the connectores tend to get heat checked and crack causing a short or poor connections.. please rate this
