Pulling Codes: Status Really Does Matter
Many modern-day fuel systems offer a new look into system status definitions. It’s become very important to extend our understanding well beyond the concepts of simple “open loop” and “closed loop” status. This month, we will explore the new fuel system definitions that are present on many of today’s vehicles. We’ll begin our discussion by looking at each one on an individual basis.
Troubleshooting Wideband O2 Sensors
Many late-model imports such as Honda, Toyota, Volkswagen and others use Air/Fuel sensors rather than conventional oxygen sensors to monitor the exhaust gases coming out of the engine. What’s the difference? An air/fuel sensor can read a much wider and leaner range of fuel mixtures than a conventional O2 sensor. That’s why they’re also called “wideband” O2 sensors.
