大众老波罗1.6前氧传感器 06A906265AR 0258005303 精确空燃比控制

If your car shows rough idle, weak acceleration, abnormal fuel consumption, and engine fault light is on, the front oxygen sensor aging or failure is likely. This sensor monitors exhaust oxygen content and feeds back to ECU to control fuel-air ratio for optimal engine operation. Compatible with older-gen VW Polo 1.6, OEM number 06A906265AR; also compatible with Lam Yi, New Bora, Skoda Fabia, Octavia and new Sageng models. Install only on a cold engine; avoid contact of sensor wire with hot exhaust components; after installation, clear fault codes and re-match ECU.
