O2 Decel Range Sample Error

Diagnostic & Technical Explanation
P2297 (O2 Sensor Out of Range During Deceleration Bank 1 Sensor 1) is a rationality monitor that runs during fuel-cut deceleration, when the exhaust should read essentially like fresh air: a sensor that fails to swing fully lean, or whose exhaust sample is implausible, gets flagged. A sensor bung leak drawing in outside air, an element contaminated with oil ash or silicone that has lost its full measuring range, and exhaust pulsations from a leaking manifold gasket upstream are the usual physical causes.

These 13 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 13 times.
