All modern vehicles are equipped with an onboard computer diagnostic system that constantly monitors the vehicle’s major operating systems. This diagnostic system communicates with the engine and transmission and adjusts performance according to set manufacturer parameters. When any of these set parameters are found outside of the acceptable range, the check engine light becomes lit.

O2 SENSOR REPLACEMENT SERVICE
An oxygen sensor monitors the exhaust for unburned oxygen, which indicates engine efficacy and the proper air-to-fuel ratio. If you have a faulty sensor, it will not provide the correct data to the onboard computer. The majority of vehicles have two to four sensors. Deterioration of the precious metals inside the oxygen sensor affects the sensors’ ability to give an accurate reading. If you put off getting an oxygen sensor replaced, it will eventually damage your catalytic converter, which can be very costly to replace.
