Common Causes of Oxygen Sensor Failure
In Pakistani conditions, oxygen sensor failure in the Toyota Camry can be attributed to factors like poor fuel quality, contaminated fuel, excessive idling, and high temperatures. The sensor can get clogged with carbon o r soot, affecting its ability to detect the proper oxygen level in the exhaust gases. This results in reduced fuel efficiency, poor engine performance, and higher emissions. Regular maintenance like fuel system cleaning, using high-quality fuel, and ensuring proper engine tuning can help prevent premature failure.
