I Have a 1992 dodge dakota And my temp gauge does not move. Do you know whats wrong with it

How do you know its wrong? What have you done to establish that opinion? Gauges are pretty reliable, you need to check the sensor on the engine, usually on the thermostat housing. They are cheap and easy to replace by someone with a little experience. Don't do it with a hot engine. If you have an old style mercury thermometer, check the water temp when warmed up against what the gauge says. Thats warm up not full running temp. 10 mins or so of idle or until the gauge starts to move.

How to check the Transmission Fluid Temperature Sensor. There is a reason for it. The sensor can skew ,a skewed sensor will mean either the computer thinks that the fluid is either too cold and thick for shifting or the computer will want to go into hot mode. Hot mode means no OD. Overdrive. Overdrive means no mechanical coupling.

Use an infra temp gun. There are two windows to a typical gun. the top window is the laser. It gives you something to point with. The bottom larger window is the infra red. This is what actually takes the temperature. Temp guns are getting cheap.

Place the gun on a hot transmission cooler line and compare the reading to the gauge.

You probably have a clog somewhere in the cooling system. Remove the hoses and flush the cooling system really well. Be sure to remove the hoses at the back of the engine as well and flush the heater core too. I bet that will solve your problem.

Have you checked base fuel pressure with a gauge ?
Code 42 is a problem with the fuel pump relay or ASD relay circuit.

try to lightly push on the gauge cluster could be in the printed circuit

first check the level of your coolant and if that is proper then i would replace the thermostat its probably wide open

hope this helps

I'd still check the thermostat. Or basically just replace it. Have you ever drained all the antifreeze and flushed the system? Good time to do both. If the hose's get real hot that doesn't really mean the thermostat open. Wouldn't they get hot even if the thermostat didnt open.? If the thermostat was stuck open you'd would have cold air and low temp gauge. Then maybe hit a pump or something and have the thermostat stick closed and have high temp. Maybe water pump. Check it when you have the belt off. Spin, pull & push the water pump pulley around. I'd replaced my water pump at about 110,000 on a '97 dodge Dakota. My 97 never had a very good heater. Always heated up more after driving. Idle never got it warmed up.

DODGE DAKOTA HAD 3 DIFFERENT ENGINES BACK IN 92. ENGINES ARE 2.5 - 3.9 - 5.2 YOU COULD HAVE THE WRONG FUEL PUMP INSTALL.WHICH WILL MAKE ELECTRICAL HOOK UP DIFFERENT.THAT WILL CAUSE FUEL GAUGE NOT TO WORK.

on the low side 35-40 psi. you really should charge by weight, then you KNOW its got the correct amount in. the way to partial charge is feel the inlet pipe and then the outlet, when the charge is full, they will be the same temp.

If its just your fuel gauge that has stopped its not a fuse... the fuel sending unit's fuse is not dedicated to just the sending unit.. Sounds like sending unit failure.
