日产奇骏2008-2014氧传感器 22680-ca000 精确进气感应 改善油耗

When Nissan X-Trail (2008-2014) shows check engine light, rough idle, sluggish acceleration, or obvious fuel consumption increase, the oxygen sensor aging or failure may be the cause, leading to air-fuel imbalance. This sensor monitors exhaust oxygen content in real time and feeds back to the ECU to control injection amount for efficiency and emission reduction. OEM: 22680-ca000 (also compatible with 22680-7s00a, AF-NS01). Use a dedicated socket during installation to avoid stripping threads; recommend cold-start operation and apply a small amount of anti-seize to prevent high-temperature sintering.
