What would cause a 2001 Pontiac Grand Am's engine temperature gauge to not work?
Coolant Temperature Sensor
Where is the 2000 Chevy Impala Coolant temperature sensor located a 3.4 engine?
The coolant temperature sensor is located on the passenger side radiator tank about 1/3 of the way down. It has a square back and faces toward the engine and is held in place by a spring clip. It has a two wire electrical connector and it is in direct contact with the radiator coolant via an o-ringed cylinder. You will loose coolant when changing it. If this sensor goes bad the A/C will not work, the temperature gauge will not work, fuel economy goes down, the low coolant light will light, and the cooling fans will run regardless of engine temperature.
What happens if the coolant temp sensor on 97 toyota camry is bad?
Your temperature gauge does not work, and the engine might run rough.
Heat and ac work but temperature gauge does not function?
Bad gauge or defective coolant temperature sensor
What does the fault code P0128 mean in 2002 Malibu?
p0128-- coolant temperature below thermotat regulating temperature---change thermostat first, and make sure coolant is ok!! then if it does not work. change coolant temperature sensor.
What causes the temperature gauge on a 1996 GMC Sierra pick-up truck to not work.?
Could be the coolant temperature sensor.
My gauge of temperature doesnt work because there was a short circuit in the instrument panel i check the fuses and its ok i change the engine coolant temperature sensor but it doesnt work how i fix?
There should be a second sensor, located near the exhaust manifold. One snesor controls the fan, the other controls the gauge.
How does a fan switch work in a car?
The fan only runs when needed to help cool the engine. The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature. Extra cooling is not needed when an engine is first started, so the fan does not come on until that engine reaches normal operating temperature which is usually from 195 to 215°F. The fan will then cycle on and off as needed to maintain the coolant temperature. So the fan runs mostly at idle or low-speed when the engine is at normal picture.
How does the coolant reservoir work?
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.
How do the engine coolant sending unit and the coolant temperature sensor work together?
The sending unit is only to control the temperiture warning light/gauge on your dash. If you are referring to the sending unit in your overflow tank it just turns your low coolant light on. The temperiture sensor is used to feed engine temperiture data into the computer, to caculate how much fuel the engine will get during cold start up etc. It is simply input data for the computer.
In a Chevrolet Cobalt the digital coolant numbers goes off then shuts off the ac?
Yes this is a safety precaution for the system to not allow the A/C system to work when the --- appear in the coolant temperature. Replace the coolant temperature sensor to get this --- to start displaying the temperature again.
Does a knock sensor and water pump work together?
No, the knock sensor helps the engine computer control ignition timing. The water pump pumps coolant through the engine, heater, and radiator.
