If you notice a check engine light on your dashboard, check the trouble codes with an OBD2 scanner or let your mechanic do it. Due to a faulty intake temperature sensor, the engine control module may think that the engine’s air is colder or warmer than it actually is.

In this article, you will learn the symptoms and the meanings of a bad intake air temperature sensor. Let’s begin with the symptoms. 1. Drop in Acceleration 2. Hard Cold Start Condition 3. EGR Valve Affected 4. Poor Fuel Economy What is an Intake Air Temperature Sensor? Where Is the IAT Sensor Located?
When does the Check Engine light come on?
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.
What does the coolant temperature sensor tell you?
The ECT sensor, also commonly just called the coolant temperature sensor, measures how hot the engine in your car is. Fuel delivery, ignition timing and engine performance are among the key elements affected by the information the coolant temperature sensor gathers.
What happens when the coolant temperature of an engine goes up?
Engine efficiency, power and fuel economy all improve as the engine temperature rises. Ideally, the engine will run as hot as possible without boiling its coolant or damaging its components. But a faulty engine coolant temperature (ECT) sensor can cause havoc on an engine or its related systems.
