The temp gauge is for the water/coolant temperature - most likely it's sticking thermostat -- if you do it yourself it's fairly cheap ($10-15 for the thermostat plus the coolant) just make sure to follow local guidelines for disposal of any coolant

I'm not sure if it would effect the EGR or not, but it's possible. Also, unless the scan results were specific enough to rule it out, most emissions issues are with the O2 sensors

check the that wire to the temp sender unit is not shorting out as it will read hot if it is remove the wire and if the gauge goes back to cold then replace the sender unit.

04 ram 1500 4.7, new radiator, fan clutch, water pump, thermostat, have flushed whole system, new heads, and intake. temp gauge still showing over heating. my lazer shows 180 - 210 . is sending unit bad?


Your sending unit is definately bad running at 180 - 210 is perfectly fine and it is not overheating at all.Replace it and your problems will be solved. But make sure you are using your lazer temp gauge at the same point as your temp sending unit.If you are then it is your sending unit if not you may have air in the system at the point of the sending unit and this will cause your problem as well.

Gas gauge in the instrument panel not working


The number most common cause of this problem is that the gas gauge sending unit (consists of a float and a variable resistor) inside the gas tank is defective. To replace the sending unit in the gas tank, the tank must be removed from the car. The fuel gauge sending unit is sold as a complete module that also contains the electric fuel pump.

My gas gauge doesn't work in my 2003 bonneville. What can i do to fix this problem, along with my broken gas gauge my heater in my drivers side seat is no longer working, i would appreciate any help thanks...


It might not be anything wrong with your fuel sending unit. Keep an eye on your other gauges. I own a 2004 Pontiac Bonneville GXP. All of my gauges have started acting erratically. It started with my Temp. gauge, moved on to my speedometer, and now my oil pressure , fuel level and batty volt gauges are affected too. Its a very common problem with GM vehicles.

Temp gauge shows hot even if engine has been off overnight?


Locate the temperature sending unit and pull the wire off of it. Turn the key to the on position (do not start) then have someone touch that wire to a ground source and the temp gauge should go from one extreme to another (cold to hot). If the gauge does that, you have a bad sending unit...if it does not move, you have a bad gauge or problem with the wiring to the gauge.

All the temp sending unit does is act like a variable resistor depending on the coolant temp...if it is bad, it will give you a false reading.

Temp gauge off charts


Are you mistaking the engine temp sensor for the engine temp sending unit? The temp sensor is for the fuel injection system and the temp sending unit is for the gauge. If you asked for a sensor thats what they sold you. You need to ask for a sending unit.
