Product Description

An air fuel ratio sensor is a lot like an oxygen sensor. It is installed in the emissions system and can sense the ratio of air to unburned fuel. It feeds this data into the vehicle computer which then adjusts either the volume of fuel coming into the engine through the fuel pump or adjusts the amount of air based on density. If the air fuel ratio sensor fails in the Honda CRV, not only will you be producing far more emissions than you should, you'll also not be operating at peak fuel efficiency. The replacement air fuel ratio sensor by Denso will solve all of these issues with a single quick purchase.
