WebNov 17, 2024 · By Brendan Baker. Nov 17, 2024. An oxygen sensor (O2) is a vital part of the fuel and emission-control system. It measures the difference in oxygen in the air on the outside of and inside the exhaust. It reports its finding to the ECU to calculate the exact amount of fuel the injector should pulse into the cylinder to create combustion. WebAn oxygen sensor is a critical component in any car’s exhaust system. Its main purpose is to determine the makeup of your car’s exhaust or emissions and relay the information to your car’s on-board computer for optimal engine performance. Your car needs to properly concoct an optimal fuel-to-oxygen ratio for combustion, and the oxygen ...
