If the coolant temperature sensor goes bad it can
send a false signal to the computer and throw off the fuel and timing calculations
. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. … This will reduce fuel economy, and may hinder engine performance.
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 do I know if my temperature sensor is bad?
- Poor Fuel Economy. …
- Irregular Temperature Readings. …
- Black Smoke from Your Exhaust. …
- Your Engine is Overheating. …
- Your Check Engine Light is On.
What does coolant 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 temp sensor cause stalling?
If the coolant temp sensor is faulty and tells the computer that the car is all warmed up when it's really not, the computer might then
reduce the amount of fuel going into the cylinders
, which could cause a cold engine to stall.
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.
How much does it cost to replace coolant 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 do you check a temperature sensor?
- 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.
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.
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.
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.
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
.
How long does a coolant temperature sensor last?
Often, the engine coolant temperature sensor must be replaced at
about 100,000 miles
. If you don't properly maintain the engine cooling system, the sensor could fail much earlier.
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
.
Can bad gas Make your car stall?
Similar to having reduced fuel efficiency, your
engine may stall if
you have bad gas in your tank. Having bad gas can also mean having diluted gas in your car. … Unfortunately, this can result in an unplanned engine stall and your car stopping suddenly.
How do I know if my thermostat is stuck open?
A thermostat stuck in the open position constantly
pushes coolant into the engine and causes a lower operating temperature
. Your temperature gauge will show a needle that barely increases or remains at the lowest setting.
