Engine Coolant Temperature Sensor Car Not Starting
What is an engine coolant temperature sensor?
An engine coolant temperature sensor (ECTS) is a device that measures the temperature of the coolant in the engine. This information is then sent to the engine’s computer, which uses it to adjust the engine’s operating parameters.
What happens if the ECTS fails?
If the ECTS fails, the engine’s computer may receive incorrect information about the coolant temperature. This can cause the engine to run too hot or too cold, which can lead to a number of problems, including:
- Engine knocking
- Reduced engine power
- Increased fuel consumption
- Engine damage
In some cases, a failed ECTS can also prevent the engine from starting.
How can I tell if my ECTS is failing?
There are a few signs that may indicate that your ECTS is failing, including:
- The engine is running too hot or too cold
- The engine is knocking
- The engine has reduced power
- The fuel consumption has increased
- The engine is difficult to start or won’t start at all
If you experience any of these problems, it’s important to have your ECTS checked by a qualified mechanic.
How can I fix a failed ECTS?
If your ECTS has failed, it will need to be replaced. This is a relatively simple repair that can be performed by a qualified mechanic in about an hour.
How can I prevent my ECTS from failing?
There are a few things you can do to help prevent your ECTS from failing, including:
- Regularly check your coolant level and top it off as needed
- Flush your coolant system every 30,000 miles
- Inspect your ECTS for signs of damage or corrosion
By following these tips, you can help keep your ECTS in good working condition and prevent it from causing problems with your engine.
