Air fuel ratio sensors, commonly known as a oxygen sensors, tend to fail within the driveability system of vehicles.

P2274 code definition O2 (Oxygen) Sensor Signal Stuck Lean Bank 1 Sensor 3 What the P2274 code means This code definition indicates that either the oxygen sensor has failed, there is an exhaust leak before the sensor, or the engine has an intake manifold leak creating a lean combustion mixture.

P2197 code definition O2 Sensor Signal Stuck Lean Bank 2 Sensor 1 What the P2197 code means This code is usually an indicator of an O2 (oxygen) sensor problem, although there are several things that can cause an O2 sensor to fail.

Oxygen sensors are one of the most important components on a modern vehicle’s engine management system.

Today’s automotive exhaust systems are much more complex than they once were.

The catalytic converter converts pollutants in the exhaust system into less toxic pollutants by using a redox reduction method.

The oxygen sensor in your vehicle measures oxygen levels in the exhaust gases exiting the engine.

Oxygen sensors help your vehicle control both the fuel and ignition systems, making it a critical component to ensure your car is running and starting smoothly.

A Check Oil light comes on and you know you need to add a quart.

When you get upset with your car and start to think it has a mind of its own, you’re not too far off from the truth.

Technology has made people’s lives so much easier, even during the time they spend driving.

A warning light comes on and you immediately worry that your vehicle is going to die in the middle of the road or at the very least not run well.

You probably don't spend much time thinking about your O2 sensor.
