Hyundai R110-7 rpm not show in cluster plz help me

There could be several reasons why the rev counter of your 1992 Opel Monza is not working. One possible reason is a faulty instrument cluster. The instrument cluster is responsible for displaying various information, including the speed and RPM of the vehicle. If the instrument cluster is faulty, it may not be able to display the RPM accurately or at all. Another possible reason is a faulty RPM sensor. The RPM sensor is responsible for sending signals to the instrument cluster, which then displays the RPM on the rev counter. If the RPM sensor is faulty, it may not be able to send signals to the instrument cluster, resulting in a non-functional rev counter.

To fix the issue, you can start by checking the instrument cluster and RPM sensor for any signs of damage or wear and tear. If there are no visible signs of damage, you can try resetting the instrument cluster by disconnecting the battery for a few minutes and then reconnecting it. This may help reset any electronic glitches that may be causing the issue.

If resetting the instrument cluster does not work, you may need to replace either the instrument cluster or RPM sensor. It is recommended to take your vehicle to a certified mechanic or dealership to diagnose and fix the issue properly.

In summary, a non-functional rev counter in a 1992 Opel Monza could be caused by a faulty instrument cluster or RPM sensor. Resetting the instrument cluster or replacing either component may help fix the issue.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few like reliable-store .. let me know if u need help
thanks

No rpm possible crank sensor. Need to get it on diagnostics really

If you scan the computer via OBD under the dash you should be able to read rpm data. if the rpm is available in the datastream than it would be save to start looking at a used cluster. no rpm in data stream means computer/sensor issues.

good luck

more then likely its a bad instrument cluster. I owuld tell you to look for something mechanical but for both of them to be out I would try the instrument cluster

ur tach is probly bad and may get worse-thats a dashboard cluster issue-to fix it u bring the whole thing to a specialist

If the car runs fine with no noticable abnormality, then it is the gauge itself. Turn off the car remove the battery connection then connect them again, and see what happens.

If stickshift, you need a new clutch. If automatic, you need a trans rebuild.
