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.

    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.

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

The car Gods created check engine lights so people don't have to guess at where to start. Get the codes read. Then you'll have a starting point. Waste of time to guess until you do that.

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.

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.

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.

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
