Temperature gauge stopped working

Engine Cooling problem
2001 Chevy Malibu 6 cyl Front Wheel Drive Automatic 80k miles

Engine Size: 3.1L Sti V6 'Good ol reliable' lol
Auto/Manual: Auto
Mileage: 125,000kms

Hi everyone! First post on this site and I hope theres some people still on this thing. And im sorry but I am going to rant!

I bought this car 9 months ago and it seemed ok (i didnt know much about mech's at the time) lets just say I had no idea of the car being the ultimate lemon in north american (i flushed out that beautiful dexcool in the dark trying to save my gaskets after reading about it lol)

Anyways about 2 months ago whilist on a two hour long journey my temp gauge died, didnt make a sound. Just stoped, stuck at stone cold. On a hot day.

Engine check light goes on next day whilist making the hours back home and this makes me nervous as I had overheating prblms on the really hot days when stuck in slow traffic and my cooling system would bleed out the surge tank saftey hose.

Ok so I read a haynes manual and it tells me that the 'Coolant temperature sensor' is responsible for the HUD gauge and for the ECM and tells the ECM when to turn on my fans. Big job for a sensor.

I bought a new sensor and just before I change it. ITS WORKING?
But not for long. It dies in a couple days again

So screw it, I got a deep socket and changed the sensor myself (in the canadian tire parking lot lol). Turn the car on and the gauge works for like a second barely making it a quater way up. And drops and dies again. Engine check light still on even after I unplugged negative battery cable for a few mins.
This is funny overheating in summer and now underheating in winter sigh*

So thats my problem
-Temp Gauge no worky
-Bad (meaning worse) gas milage
-Heater works but barely
-Engine fans always on

any ideas people? Help woud be very much appreciated

Temp gauge just stopped working

Hello,

Just recently the temperature gauge in my wifes car stopped working. I checked the owners manuel to see if there was a fuse for the temperature gauge. There was not. All the rest of the gauges are working in the instrument panel. Can you please offer me an suggestions as to why only the temperature gauge just stopped working. I'm asking with the free question because I'm unemployed and low on money. I would greatly appreciate any help you can offer. Thank you very much for your time and assistance.

There is a check engine light but it has not come on. I also noticed that the electronic engine fan seems to run all the time when the car is running. Could this be connected to the non working temperature gauge some how? Thanks for your earlier quick response.

The auto headlights and the gas gauge and temp gauge power windows and heater controls have stopped working tried everything

Fuses, relays wires they all checked out fine

My check engine came on. A few weeks later my gas and temp gauge stop working. Now the temp gauge will beep and orange light will come on letting me know car is running hot. All fluids have been checked and at right level. Also, on driver side front tire seem to have a buring smell. New tires, new brakes, now it seem to sqeak and weird noise when I hit a bump like some it going to fall off.

My 2001 Malibu gives a trouble code readout of PO 128, which according to the definition given on your website means "ECT Below Thermostat Regulating Temperature". The "Check Engine" light is on and the temperature gauge is not working. Does this mean that there is a problem with the thermostat or simply that the engine coolant temperature sending unit is not working? Thanks.

Please help. The Power Windows, Fuel Gauge, Engine Temperature Gauge, Climate Control, and Turn Signals periodically wont work. The power windows, fuel gauge, engine temperature gauge, and climate control all stop working simultaneously (which is right when the car starts, they have never stopped working during operation of the vehicle). Those 4 Electrical problems always happen together and have never happened separately. Plus, the turn signals go out while driving then will sometimes start working if, I hold down the emergency flashers button while messing with the turn signal control. Thank you in advance!

my high beam indecator light will not work, the bulb is not burned out, also the gas gauge and temp. Gauge does not work what can it be we replaced the engine and now have these problems

The fuel gauge and temp gauge went out simultaneously on my chevy Malibu 2001. The fuses are all good wondering what would effect both of them at the same time. My car has also been overheating so I really need the temp gauge.
