A bad fuel sending unit, a fault in the circuitry for the fuel sending unit, or possibly a faulty gauge.
Replace the gauge. This problem indicates an un-repairable failure inside the unit.
The problem could be a dirty sensor or the sender is no good.
Thermostat may not be opening
yes it can
change your thermostat....
If it's just the gauge jumping and there is no actual increase in RPM, then the gauge or the pickup is faulty. If the RPM is actually climbing as you drive, your transmission could be gearing down or your transmission is slipping under load, automatic or standard.

why would a speedometer stop working on a Mazda
In the fuel tank.
A common problem with Honda cars is that the fuel gauge is stuck on full. This problem is solved by replacing the gauge cluster.
you need to replace the gas gauge sending unit in the tank, or your gauge is broken
No.
