SYMPTOMS OF A FAILED ECT SENSOR

The ECT sensor is a critical part of your engine’s cooling system, and it plays a critical role in engine performance too. It monitors the temperature of the coolant and relays that information to the engine control unit. If the ECT sensor fails, it can cause a number of problems.

The most common symptom is an overheating engine. The ECT sensor is responsible for triggering the fan when the engine gets too hot, so if it fails, the fan will not turn on. As a result, the engine will continue to heat up until it seizes.

Other symptoms of a failed ECT sensor include:

• Poor fuel economy
• A check engine light
• Engine knock or ping from improper timing adjustment
• Rough idle
• And an incorrect temperature reading on the dash.

If your ECT sensor fails, it’s important to have it replaced as soon as possible. Otherwise, you could be facing major engine damage.
