Summary

Cadillac: ses light with dtcs p0171 and p0174. Complaint of ses light but it is unlikely that there will be a complaint of any engine performance concerns if this applies. Upon inspection, dtcs p0171 and p0174 will be stored and freeze frame data will normally indicate that they set at approximately the same time. This may be the result of a small air leak in the air induction system.
