Quality Time with DENSO - Lean vs Rich O2 Sensor

Oxygen sensors monitor the air fuel mixture under idle, moderate acceleration and cruise conditions. Oxygen sensors have a small range of limits in detecting and adjusting the difference from an optimum air/fuel ratio. A lean mixture can result in poor vehicle performance and even damage your engine. A rich mixture can result in unburnt fuel and an increase in emissions.
