    Hence, it is advised to have your car inspected right away to avoid any serious problems. Here is a more detailed list of the common symptoms of a bad coolant temperature sensor. One of the first symptoms you will notice is that the check engine light will activate.

    How does the ECT sensor change with temperature?

    The ECT sensor essentially is a thermistor that changes resistance with temperature. As the temperature of the coolant changes, the resistance changes on the ground signal to the powertrain control module. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low.

    How can I check the temperature of my engine?

    The system should be checked with an infrared temperature probe to see if the temperature of the engine is close to that the computer is seeing from the coolant sensor. If the coolant temperature sensor input to the computer is within about ten degrees of what the infrared tested is reading on the outside of the sensor then this would be okay.

    Your check engine light is on: If the engine’s computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light. 2. Your engine stalls: When the engine is first started, it will require more fuel in order to idle smoothly until it’s warmed up.

    Another symptom of a problem with the coolant temperature sensor is an overheating engine. The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
