The P2297 fault code in automobiles indicates an issue with the Rear Heated Oxygen Sensor (HO2S) circuit.
The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.
The cause of this fault code can be exhaust leaks before or near the HO2S, a faulty HO2S, an open or shorted HO2S harness, or a poor electrical connection in the HO2S circuit. The importance of repairing this issue lies in the fact that it can negatively impact the vehicle’s fuel efficiency and emissions. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.
The repair time is estimated to be around 1.0 hour.

P2297: Affordable Fix For Complex Fuel Pressure Issue
The fault code is P2297.
The estimated repair time is 1.0 hour. The cost of fixing the issue depends on the hourly rate charged by the auto repair shop.
The average hourly rate is between $75 and $150. Therefore, the fixing cost can range from $75 to $150.
P2297: Fuel Pressure Regulator 2 Control Circuit/Open
The P2297 code is related to the oxygen sensor in the automobile. It occurs during a Deceleration Fuel Shut-Off (DFSO) event. The Powertrain Control Module (PCM) monitors the rear heated oxygen sensor (HO2S) during this event.
The code is triggered when the measured rate of the rich to lean switch is slower than the calibrated threshold value.
This threshold value takes into account the level of oxygen in the catalyst. The P2297 code specifically refers to the oxygen sensor being out of range during deceleration in Bank 1 Sensor 1.
