Hella Oxygen Sensor

The Hella oxygen sensor (also called an O2 sensor, lambda sensor or air-fuel ratio sensor) is a replacement emissions-control component. It measures the oxygen content in the exhaust stream and sends that data to the engine control unit, which uses it to adjust the fuel mixture. Hella is a well-known OEM supplier and aftermarket brand with long experience in automotive electronics and sensor technology.

Key Features:

• Monitors exhaust oxygen content so the engine control unit can keep the air-fuel ratio accurate
• Helps support efficient combustion, fuel economy and low emissions
• Made to meet the quality standards expected of an OEM-level replacement part
• Available in upstream and downstream sensor designs, depending on the part number
• Direct-fit replacement for the sensor it replaces, with a connector and wiring matched to the application

A worn or failing oxygen sensor can cause a check engine light, rough running, poor fuel economy and higher emissions. Replacing it with a quality Hella sensor helps restore proper engine management and emissions performance.
