Exhaust Emission Control

Lambda probes, or oxygen probes, measure the amount of oxygen in the exhaust of your vehicle. A control unit is then able to determine whether the engine is running rich (too much fuel) or lean (too little fuel). Adjustments can then be made to either the fuel injection or the air intake to balance the air-fuel ratio. A faulty Lambda probe can cause a reduction in fuel economy and a replacement unit should be found for your vehicle at Ottocarparts.com.
