Like all precision engineered automobiles of today, the Mitsubishi Eclipse operates at its peak within definite parameters and ranges, requiring that periodic maintenance be performed as scheduled. One key to engine performance and efficiency is the Mitsubishi Eclipse Oxygen Sensor. A certain ideal ratio of fuel to air is important in order for the engine to run at its peak while minimizing exhaust emissions.

The lowest emissions occur when your engine runs on a leaner fuel-air mixture - that is, when the ratio of air to fuel is higher. The Mitsubishi Eclipse Oxygen Sensor detects the amount of oxygen in the exhaust gases, then sends an electronic signal to the fuel-injection system if the mixture is too rich (contains more fuel than air) or too lean for current conditions - in essence, fulfilling the function of the choke knob on old vehicles.

An oxygen sensor needs the vehicle to be at its full running temperature to operate - otherwise, these signals are not sent to the fuel injectors until the engine was warmed up. When your oxygen sensor is faulty, it can result in poor performance, increased fuel consumption, and foul smelling exhaust. If you notice any of these symptoms and cannot find another reason behind it, chances are its time for a new Mitsubishi Eclipse Oxygen Sensor.
