Tech Tip: Oxygen Sensor Types, Technologies and Common Failures

The purpose of the engine management system (EMS) is to apply the correct amount of gasoline to the air entering the engine, while igniting the compressed air/fuel mixture at the right time within the cylinder. When an average Stoichiometric ratio of 14.7 lbs. of air to 1 lb. of gasoline is maintained, the EMS provides adequate oxygen for the reduction of harmful pollutants, as well as a rich enough mixture to prevent the catalyst from overheating.

Tech Tip: Hyundai Has Check Engine Light On with Fuel System Lean Code

The check engine light is on with a post catalyst fuel system lean code P2096, an oxygen (O2) sensor stuck lean B1/S2 code P2270, and an O2 sensor no activity B1/S2 code P0140.

Bosch Named Exclusive NASCAR Performance Partner, Oxygen Sensor Supplier for NASCAR Fuel Injected Engines

Bosch developed and introduced the automotive oxygen sensor in 1976, and as NASCAR makes the switch from carburetion to fuel injection in 2012, Bosch will be its exclusive oxygen sensor supplier.

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.
