This lambda sensor monitors oxygen levels in the exhaust stream and relays data to the engine control unit to optimize fuel mixture and emissions. Removed from a 2004–2012 Opel ASTRA H with the 1.4-litre Z 14 XEP petrol engine. Verify the OEM connector type and sensor thread size match your original unit before ordering, as fitment varies by model year and emissions specification.
