1996 prelude temperature gauge reads low temp
I'm not sure about a 1994 Prelude but if it were a 1992 Prelude this may be 2 separate problems, fuel guage issue may be the fuel guage sending unit, the temp guage may be a stuck open thermostat. Have the engine temp checked after driving at least 5 miles, does the gas guage ever move around even a little, if so it is the fuel gauge sending unit in the tank.
why doesn't my rpm gauge and temp gauge, fuel gauge not work
temp gauge is stuck on hot
only 3 reasons a temp gauge wont work the temp sender is bad the gauge is bad or the wire from temp sender to gauge is broken
The temp sending unit for the temp gauge is located on the drivers side of the engine between cylinders 3 and 5 spark plugs.
Thermostat stuck open or no stat at all. Faulty temp sensor or Gauge.
Replacing the gauge could be a costly job but it is seldom the gauge goes bad. More likely the temp gauge sending unit is at fault. Replacing the temp gauge sending unit would take less than 15 minutes.
If your temperature gauge isn't working the problem is a bad gauge, grounded or disconnected wiring or, most likely, the temp sender isn't working.
Test gauge function with a mechanical gauge to get actual engine temp.
i change the thermostat and the temp switch but still not working
A faulty temp sending unit can do that.
Defective temperature sensor or bad gauge
