Car Oxygen Sensor Lambda Sensor O2 Snesor Part Number 25106073 For Daewoo / Chevrolet / Opel / Vauxhall

The 25106073 Lambda Sensor (also known as an O₂ Sensor, Oxygen Sensor, Exhaust Gas Sensor, EGO Sensor, or HEGO Sensor) is an original equipment component manufactured to GM, Opel, and Daewoo OE specifications. It is used across a broad range of GM-family vehicles from the late 1980s through the 2000s, including Daewoo, Chevrolet, Opel, Vauxhall, Buick, Cadillac, GMC, Holden, Oldsmobile, Pontiac, Citroën, and Suzuki applications.

Because this OE number spans multiple configurations, the specific sensor technology (heated or unheated, switching or regulating), connector pin count, and cable length vary by vehicle application. Always confirm the original sensor type before ordering.

• This sensor is used across a wide range of GM-family vehicles from the 1990s through the 2000s. The specific technology (heated vs. unheated, switching vs. regulating) varies by application — always confirm the original sensor type before ordering.
• Cable length variations: Documented cable lengths for this OE number include 410 mm (Febi, Blue Print), 285 mm (Hella), and 445 mm (alternative reference). Always measure your original sensor's cable length.
• The threads are M18 × 1.5, compatible with a standard 22 mm (7/8″) oxygen sensor socket.
• Connector pins: Some references list a 1-pin configuration, while others may specify a multi-pin connector. This reflects the varied applications for this OE number. Verify the connector shape and pin count on your original sensor.
• Also known as: O2 Sensor, Lambda Sensor, Exhaust Gas Sensor, EGO Sensor, HEGO Sensor.

• Always verify the specific sensor type (heated/unheated, pin count) for your vehicle — this OE number spans multiple configurations.

This Lambda Sensor is an original equipment component used across a wide range of GM-family vehicles and related platforms. Because the specific sensor configuration (heated/unheated, upstream/downstream) varies by application, the position and type must be verified against your original sensor.

• This sensor is widely used across the GM T-platform and related global small-car platforms from the late 1980s through the 2000s.
• Primary applications include Daewoo Lanos, Nexia, Espero, and Cielo; Chevrolet Lanos and Aveo/Kalos; Opel Ascona, Astra F, Corsa B, Kadett E, Vectra A, and Vectra B; Vauxhall Astra, Corsa, and Cavalier.
• Position and type vary by application. For many Daewoo Lanos and Opel Astra/Corsa applications, this is an upstream (pre-catalyst) sensor. For other applications, it may be used downstream. The sensor may be heated or unheated depending on the specific engine management system (e.g., Multec, Simtec, or early GM systems).
• How to verify: Locate your vehicle's catalytic converter and inspect the original sensor. Confirm whether it is before or after the converter, whether it has a heater circuit (extra pins), and match the connector shape and pin count to the replacement part.
• Not compatible with diesel engines — diesel applications use different sensors with different calibration parameters.
• The vehicle fitment information above is a guide only. Always confirm compatibility using your vehicle's VIN or by physically inspecting your old sensor's position, connector shape, pin count, and cable length before ordering.
