The Nissan Altima Air Fuel Ratio Sensor is an important component of your car or truck's engine. It works in conjunction with the data processor to monitor the amount of oxygen funnelled into the engine cylinders and determine whether the fuel vapour fed to the motor needs to be adjusted. If the air-fuel ratio is not rich enough, this can result in reduced performance, while a too-rich fuel mix may cause damage to the motor and large quantities of unburned fuel from the exhaust pipe. This guide will take you through the steps to replace the air fuel ratio sensor in your Nissan Altima.
