Keeping your car in good condition is essential for its performance and longevity. One of the components that play a crucial role in your car’s engine performance is the map sensor. A dirty or faulty map sensor can cause a range of problems, including poor fuel economy, rough idling, and engine misfires. In this article, we will discuss how to clean a map sensor and improve your car’s performance.
What is a Map Sensor?
A manifold absolute pressure (MAP) sensor is a component in your car’s engine management system that measures the pressure inside the intake manifold. The data collected by the map sensor is used by the engine control unit (ECU) to adjust the fuel injection and ignition timing. This ensures that the engine runs smoothly and efficiently.
