Which fuse is for temperature gauge on dashboard


  • The temperature gauge is not on a fuse of its own, it would work with all the instruments, ie fuel gauge, warning lights etc. If the temp gauge does not work and the fuel gauge does,, look for the problem elsewhere such as the sender unit on the engine. A quick check is to remove the wire from the sensor unit on the engine and short it out to ground. If the gauge picks up, replace the sensor unit.
  • Otherwise, check the wire itself for breaks, or bad connections.

Mazda temperature gauge


When the gauge doesn't work, you have to determine, is it the gauge on the dash or the temperature sending unit on the engine or a wiring problem. Try this: find the sending unit on the engine and pull the wire off it. With the ignition key on, touch the wire to a metal ground on the engine. Does the temp. gauge move? If it does, replace the sending unit. If it doesn't move, replace the temperature gauge on the instrument panel.

Temperature gauge not working


Hi there,
My name is Steve. I can tell you that the barometric pressure sensor can, in no way, effect the temperature gauge operation. The gauge gets a signal from the engine computer which, in turn, gets a reading from the coolant temperature sensor. Your first step should be to have the check engine light diagnosed properly...starting with checking for codes. You likely have a code(s) relating to engine temperature or the temperature sensor circuit. Most common problems are erratic sensor operation and corrosion or oil contamination in the coolant temperature sensor connector. You will be time and money ahead by having a professional diagnose the problem correctly before deciding to buy any parts.

Why won't the oil and temperature gauge work on


you should switch the temperature sensor and oil pressure sensor you had on your first engine,because your new engine must come with the light indicator dashboard so the sensor of your new engine are not compatible with your gauges....lipak!...

Audi A3 2002 model auto - temperature gauge not working


The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.

Heating System


The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

See Figures 3 and 4
  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.
