Why is my Vauxhall Combo Life's RPM gauge not responding?

I have noticed that my Vauxhall Combo Life's RPM gauge does not respond when I accelerate. The gauge stays at 0 even when I am moving. What could be causing this issue?

The most common reason for this issue is a faulty RPM sensor. You may need to replace it to fix the problem.

Another possible reason could be a loose or damaged wiring connection. Check all the connections and make sure they are secure.

It could also be an issue with the gauge itself. If the sensor and wiring are all fine, you may need to replace the gauge.
