- 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.
Owners of these vehicles have filed 168 complaints in the transmission category.
