2. What happens when a ECT sensor goes bad?
When the Engine Coolant Temperature (ECT) sensor fails, it can disrupt the engine's fuel mixture regulation. This can result in a rich-running engine, which leads to poor fuel economy. Additionally, a malfunctioning ECT sensor may prevent the car from switching to a more precise reading from the oxygen sensors when the engine is warm.
3. How much does it cost to replace a temperature switch?
The cost of replacing an Engine Coolant Temperature (ECT) sensor can vary, but on average, it ranges between $398 and $438. The labor costs are estimated to be between $93 and $118, while the parts themselves cost between $305 and $321.
4. Can you drive with a bad temperature sensor?
Driving with a failing or failed coolant temperature sensor is not recommended. A faulty sensor can lead to engine overheating, which can cause damage to the engine and other components. It is important to get the sensor fixed right away to avoid expensive repairs.
5. Can you drive with a broken ECT sensor?
