why is the temperature gauge not moving on a 2007 Lincoln mkz
The thermostat is probably stuck in the open position.
Because it is a Pontiac. Sorry, man.
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
mostly likely something wrong with the sensor or gauge.
Coolant Temperature Sensor
sounds like the fuel sensor inthe fuel tank which means removing tank to replace
Yes, there is a fuse for this. It should be labeled INST.
you will need to replace the fuel sensor and it is all in one with the fuel pump its in the gas tank.
I had this problem with my 2002 montana. The fuel gauge inside the tank was defective I went to a garage where and had the gauge changed (you can buy the part from the dealer ) You have to take the fuel tank down and unplug the wires and the fuel lines(you need a special tool to disconnect the fuel lines) Parts and labor cost me $260.00
The most likely cause is a broken wire or blown fuse.
Idle the engine, remove the temp sensor wire on the engine and ground it. If the gauge does not move one can assume it has failed.
There are two...one that sends a signal to the gauge and one that sends a signal to the computer.
The engine coolent may be low enough that sensor is not surounded with coolent when engine is not running.
My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.
replace temperature gauge
Probably low coolant or a faulty thermostat
Get the head gasket problem fixed.
If your engine light comes on and your temp gauge is lower then normal. listen for cooling fans. if they are also running chances are you need a new thermostat
Not likely. It's probably the Water Temperature Sending Unit located on the engine, or the signal processor on the instrument panel (not likely).
Fuse location for temperature gauge for a Malibu
Defective temperature gauge or defective temperature sensor?
probably means u need to change the coolant for the car,leaking coolant sumwhere
Bad gauge or defective coolant temperature sensor
Go to a Pontiac Mechanic and spend a few bucks.
