These sensors play a critical role with fuel monitoring, delivery, MPG and timing as well as Emissions release. The O2 sensor is the ECM's main input for determining how much fuel to inject into the engine. If the ECM reads that theres too much oxygen, it will adjust other sensors to add more fuel and vice versa. Not only will the bad oxygen sensor cause engine troubles, but it can also lead to further damage to other components. Let it cool for awhile before touching it. The oxygen sensors must be in optimal working order to keep the catalytic converter from damage.
