Hella Oxygen Sensor Lambda Probe

The Hella oxygen sensor (lambda probe) monitors the oxygen content in the exhaust gas and sends this information to the engine control unit. The ECU uses the signal to adjust the air-fuel mixture. This helps the engine run efficiently, keeps emissions low, and supports proper catalytic converter operation. It is also known as an O2 sensor, lambda sensor, or air-fuel ratio sensor.

Key Features:

• Measures residual oxygen in the exhaust stream for accurate closed-loop fuel control
• Helps maintain fuel economy, drivability, and emissions performance
• Engineered by Hella, an established OE supplier to the automotive industry
• Designed for reliable signal output and long service life under high exhaust temperatures
• Replaces a worn or failed sensor, a common cause of a check engine light, rough running, and higher fuel consumption

Replacing an aging oxygen sensor can restore efficient engine management and help keep the exhaust system working as intended. Select the specific part number from the available options for the correct connector and sensor configuration.
