Can a bad MAP sensor cause engine failure?
MAP sensor on footwell inside engine compartment. A bad manifold absolute pressure (MAP) sensor can upset fuel delivery and ignition timing. Depending on your vehicle model, your engine might experience one or more of these performance problems: However, these symptoms are not exclusively symptoms of a failed MAP sensor.
How does a MAP sensor work on a car?
What Does a Map Sensor Do? Basically, a MAP sensor reads the amount of air pressure in relation to vacuum inside the intake manifold, either directly or using a vacuum hose. Then, it translates this pressure into a voltage signal that the sensor feeds to the power control module (PCM), your car’s computer.

What does the MAP sensor read at sea level?
When at rest, the MAP sensor reads atmospheric pressure at sea level (29.93 in. Hg). Because atmospheric pressure varies with weather and altitude, the ECM calculates this “zero” point just before the engine starts, fine-tuning spark and fuel injection mapping from that point.
