DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-9124
DENSO Auto Parts 234-9065 air / fuel ratio sensor for the 2006-2009 Honda S2000 4-cylinder 2.2L and other vehicles measures the air-fuel ratio in the exhaust and sends that reading to the engine computer. This upstream sensor is a direct-fit part built for exact replacement.
A worn air-fuel ratio sensor can show up as a check engine light, rough running or poorer fuel economy. Before you replace this sensor, rule out a damaged wire or connector and an exhaust leak near the sensor, since those can also set the light or hurt economy.
This air fuel ratio sensor fits the 2006-2009 Honda S2000 4-cylinder 2.2L and the 2005-2006 Acura RSX 4-cylinder 2.0L, and each takes one.
