Here are some reasons for this:
Emissions Control: 02 sensors are crucial for controlling emissions by monitoring the amount of oxygen in the exhaust gas. Based on this information, the engine control unit (ECU) adjusts the air-fuel mixture to maintain optimal combustion, reducing harmful emissions such as hydrocarbons, carbon monoxide, and nitrogen oxides.
Fuel Efficiency: 02 sensors help optimize fuel efficiency by ensuring the correct air-fuel ratio. A properly functioning 02 sensor allows the engine to operate at its ideal stoichiometric ratio, maximizing fuel efficiency.
Engine Performance: 02 sensors provide feedback to the ECU about the engine's combustion efficiency. This information is used to adjust various engine parameters, such as ignition timing and fuel injection, to optimize performance and prevent engine damage.
Emissions Regulations: Many countries and regions have stringent emissions regulations that require vehicles to be equipped with 02 sensors. Honda vehicles must comply with these regulations to be legally sold in those markets.
Therefore, Honda cars need 02 sensors to ensure emissions control, fuel efficiency, engine performance, and compliance with emissions regulations.
