What is the purpose of the Oxygen (O2) sensor in the ECM for the Honda Prelude?

ECM uses the Oxygen (O2) sensor to check for oxygen levels in the exhaust system and adjust the air fuel ratio for optimal engine efficiency. They help to improve response time as well as stability of the Heated Oxygen (HO2) Sensors. OBD-II has been requiring two HO2 sensors since 1996: a Primary Heated Oxygen (PHO2) sensor, which checks gases coming out of exhaust manifolds before catalyst converters; then a Secondary one called Heated Oxygen (SHO2) that controls PHO2 sensors and catalytic converter efficiencies. The ECM/PCM talks to the HO2 sensor, adjusting air/fuel mixtures to cope with lean or rich signals. Removals and installations must be handled carefully so as not to damage these sensors.

Honda Prelude Oxygen Sensor

The function of Oxygen Sensor in Honda Prelude is to maintain the detection of the air fuel mixture in the exhaust emissions to achieve maximum combustion efficiency. The ability to bring voltage signals of the unburned oxygen to the engine control computer enables air/fuel changes. Most Honda Preludes employed zirconium dioxide sensor with platinum electrodes in a ceramic and steel housing for detecting the oxygen proportion in the exhaust. High temperature sensors which are very vital in the functioning of the catalytic converter are located here. The latest Honda Preludes use at least two oxygen sensors, one positioned before and the other after the catalytic converter to feed back information to the ECC. The upstream one works by transmitting voltage signals to fine-tune the air and fuel mixture while the downstream one to inspect the catalytic converter's effectiveness. The oxygen sensor usually fails in a way that increases emissions and decreases fuel efficiency and therefore should also be replaced. For the new cars air fuel ratio can be used sensor which provides greater coverage for better accuracy in the fuel control.
