Accord 2.4 CM5 7th Generation Oxygen Sensor 36531-RAA-A01 with 234-9040

Honda Accord 2.4 CM5 7th generation owner note: Oxygen sensor with OEM number 36531-RAA-A01 and common 234-9040; direct replacement with no wiring modification. Monitors oxygen content in exhaust and transmits to ECU to precisely adjust air-fuel ratio. For Honda Accord 2.4L CM5, replacement effectively solves high fuel consumption, weak acceleration, and check engine light. If idle is unstable, exhaust smells of unburned fuel, or fuel consumption rises abruptly, oxygen sensor aging requires replacement.
