Yes. Sensors like MAF Mass Air Flow and MAP Manifold Absolute Pressure often cause:

Sudden RPM s

Check engine light

Stalling o r hesitation

In Pakistan, common causes of sensor failure include:

Water damage during engine bay washes

Loose connectors o r poor-quality wiring

Dust accumulation due to missing o r clogged air filters

Sensor quality and sealing seem to be below-par, and replacement parts are expensive o r scarce.
