Nissan Qashqai 1.2T Front Oxygen Sensor 22690-00Q1L Improves combustion efficiency, reduces fuel consumption

Nissan X-Trail 1.2T front oxygen sensor 22690-00Q1L directly replaces OEM, widely compatible and designed for 1.2T X-Trail. Monitors exhaust oxygen, sends signal to ECU to adjust fuel injection, improving combustion efficiency and reducing fuel consumption. After installation, idle improves, acceleration improves, and emissions reduce. If fuel consumption rises, engine warning light on, or rough startup occurs, oxygen sensor aging is suspected; replace promptly.
