Nissan X-Trail 2008-2014 Oxygen Sensor 22680-ca000 Precise Intake Sensing, Improves Fuel Economy

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.
