P2497: Exhaust Gas Recirculation Cooler Bypass Position Sensor Circuit — Bank 2
What to do
As P2492 — and the one-bank-or-both question is free evidence on a V engine.
What this code means
Bank 2's bypass position sensor has failed its circuit checks — P2492's witness on the other bank, with the same safe-parked fallback and the same bank-split bonus V engines always provide: one bank's flap misbehaving while the other answers cleanly localises the fault without a measurement.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
