Could map sensor cause car to stall?

Yes, a faulty manifold absolute pressure (MAP) sensor can cause a car to stall. The MAP sensor measures the pressure in the intake manifold, which is crucial for the engine control unit to determine the correct air-fuel mixture. If the sensor provides incorrect readings, it can lead to an improper fuel mixture, resulting in poor engine performance and potentially causing the engine to stall. Regular maintenance and timely replacement of a malfunctioning MAP sensor can help prevent such issues.
