Map Sensors

A map sensor, or Manifold Absolute Pressure sensor, measures the pressure inside the intake manifold of an internal combustion engine. It provides crucial data to the engine control unit (ECU) to optimize fuel injection and ignition timing for better engine performance and efficiency.

You should consider replacing the map sensor if:

1. Engine Performance Issues: The engine may experience rough idling, stalling, or lack of power.
2. Check Engine Light: The check engine light may illuminate, often accompanied by error codes related to the map sensor.
3. Poor Fuel Economy: A failing map sensor can lead to incorrect air-fuel mixture adjustments, reducing fuel efficiency.
4. Increased Emissions: Faulty readings can lead to higher emissions due to improper combustion.
5. Difficulty Starting: The engine might have trouble starting or may not start at all if the sensor is malfunctioning.
