By measuring O2 levels in the exhaust manner, O2 sensors state engine timing and fuel mixture
Faulty oxygen sensors disrupting engine timing and fuel/air mixture can raise the emission of pollutants into the atmosphere. This, in turn, can cause the car to fail emissions inspections
Poor Timing
A damaging sensor can disrupt the combustion cycle that is controlled by the vehicle's machine, and it basis your engine to flight Rugged or "miss" while idling or running at relatively low RPMs. The faulty sensor can also cause the engine to knock and ping as the combustion of the fuel in the chambers of the engine is thrown out of its normal timing sequence.
Poor Mileage
If the engine ignition system is disrupted, the system for delivering fuel to the combustion chambers can also become faulty, causing too much fuel to be pumped into the engine. It can also result in a loss of engine power and lower gas mileage.
Emissions
The O2 sensor in your machine or Motor lorry monitors the common of O2 in your vehicle's exhaust. The sensor is linked to the on-board personal computer, which adjusts the fuel mix and engine timing to compensate for any changes in the O2 common and optimize the fuel/air alloy. Whether the O2 sensor is impaired or damaged, it can influence the system of the engine, if idling, accelerating or decelerating.
