Are poor fuel quality and unfiltered air in Pakistan causing deposits on sensors like the O2 o r MAF sensors in Alsvin?

Could locally available low-octane o r adulterated fuel be damaging these sensitive components, leading to faulty readings?

Yes. These are major contributors to sensor failure:

Low-octane o r adulterated fuel leads to incomplete combustion and carbon buildup on O₂ sensors.

Unfiltered o r polluted air introduces dust into the intake, clogging MAF/IAT sensors.

The absence of high-quality fuel filters o r air filtration systems in cheaper trims aggravates the issue.

Result: degraded sensor readings, delayed throttle response, and increased emissions.
