DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-9018
DENSO Auto Parts 234-9146 air / fuel ratio sensor for the 2015-2020 Honda Fit 4-cylinder 1.5L measures the air-fuel ratio in the exhaust. It is a wide-band sensor for the upstream position.
A worn air-fuel ratio sensor can bring on a check engine light, rough running or lower fuel economy. Those signs alone do not prove the sensor is at fault; an exhaust leak is another common cause.
This is a direct-fit replacement for the 2015-2020 Honda Fit 4-cylinder 1.5L (L4-1.5L). The listing is one sensor for the upstream position, and this engine takes one.
