Fuyi Bote 1.5 Front Oxygen Sensor CV1A-9F472-AA, precisely detects air-fuel ratio

When your Fuyit Bot 1.5 model experiences idle instability, noticeably higher fuel consumption, weak acceleration, or check engine light on, likely front oxygen sensor aging. Normal operation sensors monitor exhaust oxygen content and feed ECU to adjust fuel injection to maintain optimal air-fuel ratio for better economy and power. OEM number CV1A-9F472; fits Fuyit Bot 1.5 series. Installation: use a dedicated socket to remove sensor to avoid thread damage; clean exhaust manifold interface before installation and apply a small anti-seize; torque must follow service manual; over-tightening can deform the housing.
