日产骐达前氧传感器22693-1KC0A 混合气精准调节 排放更环保

Nissan Tiida pre-cat oxygen sensor (OEM 22693-1KC0A) mounted on exhaust manifold; monitors exhaust oxygen content and feeds ECU to adjust air-fuel ratio for optimal operating conditions. Compatible with 2011-2017 1.6L Tiida models. Installation difficulty: medium; labor about 0.5-1 hour; avoid damaging threads and wiring during removal/installation. When encountering rough idle, increased fuel consumption, weak acceleration, or check engine light, sensor likely aging or failed; replacement restores precise mixture control and reduces emissions.
