The 2008 gmc envoy engine coolant temperature sensor is located in
the coolant pipe, below the air intake pipe and behind the right cylinder head
and is integral with the ect sensor.
Where is the temperature sensor on a 2008?
The coolant temperature sensor in a 2008 Chevy TrailBlazer with the 4.2L engine can be found
on the radiator on the right hand side of the engine
. This will measure the temperature of the coolant as it leaves Your engine and heads into Your radiator.
Where is my temperature sensor located?
It is most often located
close to the thermostat of the cooling system or inside of it
. The cooling system is located beneath the air intake pipe and behind the right cylinder.
What happens when a temperature sensor goes bad?
If the coolant temperature sensor goes bad it can
send a false signal to the computer and throw off the fuel and timing calculations
. … This will cause the computer to think the engine is cold, even when it is not, and as a result will use more fuel than necessary.
What are the signs of a bad temperature sensor?
- Poor Fuel Economy. …
- Irregular Temperature Readings. …
- Black Smoke from Your Exhaust. …
- Your Engine is Overheating. …
- Your Check Engine Light is On.
Can you drive with a bad temperature sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor
as the management system defaults to a static reading. A vehicle's coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.
How much does it cost to replace temperature sensor?
The average price for an engine temperature sensor replacement is
between $150 and $193
. Labor costs are between $82 and $105 while parts are between $66 and $88.
How long does it take to replace a coolant temperature sensor?
The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for
a minimum of one hour
.
Does the coolant temp sensor control the fan?
The sensor works by
measuring the temperature
that's being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. … As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
How do you clean a temperature sensor?
- Wash The Thermometer In Warm Water. Washing your thermometer probe wish warm water will remove any residue that may be on the probe, and it'll help start the sanitizing process. …
- Sanitize The Thermometer With Alcohol. …
- Rinse The Thermometer. …
- Air Dry The Thermometer.
Is there a fuse for coolant temperature sensor?
There isn't one per se
. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable “resistance to ground,” which the temperature gauge in the dash is reflecting.
Can a bad coolant temp sensor cause hard start?
If the sensor is reading too high of temperature when compared to the ambient air temperature sensor when first started then the computer would see it as a problem and turn on the check engine light to use a known good reading.
No start will not be caused by the sensor
.
What does a temp sensor do?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is
used to measure the temperature of the coolant/antifreeze mix in the cooling system
, giving an indication of how much heat the engine is giving off.
Can a bad coolant temp sensor cause rough idle?
HOW THE COOLANT SENSOR AFFECTS ENGINE OPERATION. … A faulty coolant sensor that always reads cold may cause the fuel control system to run rich, pollute and waste fuel. A
coolant sensor that always reads hot may
cause cold driveability problems such as stalling, hesitation and rough idle.
How do I know if my temperature sensor is working?
- How to test a faulty thermocouple or resistance thermometer?
- Check if the -ve and +ve leads swapped.
- Check for any thermocouple cable wiring issues.
- Check for local heat source issues.
- Check Temperature Transmitter Settings.
- Check temperature controller settings.
- Troubleshooting temperature sensors with a multimeter.
Why do temperature sensors fail?
Temperature sensor failures are common in cold applications when standard sensors are used. Why? Because
the seals of most sensors are not designed to withstand the severe material contraction that occurs at low temperatures
.
