P2197

Fix code P2197 Oxygen air fuel sensor signal stuck lean Bank 2, Sensor 1

This is a manufacturer-specific trouble code for Toyota vehicles. It refers to the air-fuel sensor. The air-fuel sensor in Toyota vehicles is a more sophisticated oxygen sensor than you’ll find on other makes. It’s more expensive too, so don’t automatically assume that you can get by with throwing a new one in. The sensor could be telling you the truth and you really do have a lean condition going on.
