SOURCE: temperture gauge

It's either a loose wire on the sending unit, or the sender itself. Or i suppose it could even be the gauge, but i'd bet on the one of the other 2.

What would cause temperature gauge bouncing ?


Sounds like the sending unit has an intermittent short to ground. Unhook the the wire from the sending unit, and see if the needle stops jumping around. If it quits jumping around, replace the sending unit. If it still jumps around, you have a bare spot somewhere on the wire and it is hitting ground which will cause the needle to jump. Cut out the bad part of the wire and splice in a new section. That should fix it.

Temperature gauge on Nissa Altima 2.4


Well it could be the gauge on the dash or the sending unit on the engine. But it could also be low on coolant or a problem with the thermostat. I would check the circuit for the gauge first if the radiator is full of coolant.

I don't think it's the thermostat, so much, as the circuit for the temperature gauge which includes, wiring to the cts (coolant temperature sender), the cts itself, and the gauge. It's likely a wiring problem if it randomly bounces from normal to hot while driving the vehicle or standing still.

Erratic temp guage but not overheating


Probably the sending unit, and cost about $30.
The test of the gauges is to remove wire from sending unit and watch gauge go to lowest, then ground the wire and watch it go to highest.
If it does, then not a problem with gauge. So must be sending unit.

Temp gauge bouncing up an down


That vehicle has two coolant temp sensors on it, both are on the passengers side of the end of the head, where the thermostat housing is. One has a two wire plug, this one tells your fans to come on the other is one single pin, this one is for your temp gauge. This sensor works off resistance, the higher the resistance the higher the gauge in the car goes. This sensor has probably grounded out and pegged your gauge in the car. Replace that sensor and you should be good to good, not too expensive either. Good luck.

Temp gauge bouncing


First, try checking the connections behind the dash that link together at the temperature gauge and make sure they haven't torn or ripped. If that doesn't help, then check/replace all the sensors which relate temperature to the gauge, ie: air temperature sensor, coolant temperature sensor, etc...Hope this helps, good luck.
