What Can Damage Your Car’s Oxygen Sensor?

Oxygen sensors, or O2 sensors, are small instruments in your car that measure the amount of oxygen in the exhaust. As you may know, your engine needs When there is a lack of oxygen, the engine runs rich, making it challenging to accelerate. 


Common Causes for Failing Oxygen Sensor

The typical causes for faulty O2 sensors include faulty wiring, electrical problems, poor insulation, and clogged fuel injectors. When your engine suffers from drastic pressure changes, it can affect the air pressure. Additionally, corrosion from improper combustion, poor heating, electrical voltage spikes from poor grounding, and dirty air filters.
