What Does HEGO Stand For?

HEGO stands for Heated Exhaust Gas Oxygen

HEGO, which stands for Heated Exhaust Gas Oxygen, refers to a sensor used in automotive emissions control systems. It measures the oxygen content in the exhaust gases after combustion, providing critical feedback to the engine control unit (ECU) for optimizing air-fuel mixture and ensuring efficient combustion. The heated component of the HEGO sensor allows it to function effectively even in varying temperatures, thus enhancing its accuracy and reliability in emissions monitoring and regulatory compliance.
