temp gauge

Hey guys, not sure what's up but my temperature gauge is goin all the way up and down while im driving and It has done it like right as I've turned it on so I know my engine actually isn't and couldn't change that fast. Any thoughts?

I would check the wiring. Sounds like it has a break or short in the temp wire causing it to change its own resistance values making the gauge jump around as you hit bumps or whatever.

Drivers side of the engine rear of the cylinder head a one wire connector to the sensor. Purple wire remove and ground to the engine aand the gauge should peg full hot. That will telll you gauge is good. Not bad to change usually <$10.

It reads nothing. Like it just doesn't work. Is it supposed to do that or go all the way up?

If you ground the spurple wire to the engine it is supposed to peg the gauge needle all the way hot. So if it doesn't mmove the gauge is bad. If it does move the sensor is bad.

Check the gauge as Joker suggests but it may also be the plastic circuit pathway, wiring to and from the gauge to the sender or just cruddy terminals at the gauge itself. Mine would barely read anything until I hard wired the gauges. Lo and behold the temp gauge works just like it should!
