P2499: Exhaust Gas Recirculation Cooler Bypass Position Sensor Circuit Low — Bank 2
What to do
As P2494 — ordinary wiring-first sensor work.
What this code means
Bank 2's bypass position circuit reads at the bottom of its range — electrical, wiring first, and the last of P24xx's decimal-numbered slots: the block's first hundred close with this entry, its span running from the leak-detection pump that hums to itself in a parked car to the flap that keeps a cold engine's exhaust warm.

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.
