Bulletin Summary
Tech line summary article - Is the MIL on with DTC P2271 (secondary HO2S [sensor 2] circuit signal stuck rich)? What's likely causing this is the PCM is misinterpreting the A/F sensor (sensor 1) signals, causing the PCM to think that sensor 2 is stuck rich. To fix this issue, replace both sensors.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
