Rear 4-Wire Heated Oxygen Sensor Lambda Probe For Porsche Cayenne Replacement Exhaust Sensor
Upgrade your Porsche Cayenne’s exhaust management with the WEIDA AUTO PARTS Rear O2 Oxygen Sensor (Lambda Probe). This rear sensor is a 4‑wire heated, piezoelectric lambda sensor designed to monitor exhaust gases after the catalytic converter, helping your engine maintain the optimal air–fuel mix even during cold starts.
Compatible with a broad range of models, including Porsche Cayenne and Audi A3, A4, A5, A6, A8, Q3, Q5, TT quattro from 2004 to 2018. The sensor uses OEM references 06J906262N, 06J906262K, and 0258010038 to ensure a precise fit for your vehicle’s ECU calibration.
Benefits include improved fuel efficiency, reduced emissions, smoother idle, and protection for the catalytic converter by providing accurate lambda readings to the engine control unit.
