P2496: Exhaust Gas Recirculation Cooler Bypass Position Sensor Circuit Intermittent/Erratic — Bank 1
What to do
Pattern notes as ever — plus any new rattle from the EGR plumbing, which points at the linkage rather than the wire.
What this code means
The bypass position signal is cutting in and out — exhaust-adjacent wiring, convicted the standard way. A flap chattering against a worn linkage can also produce genuinely erratic position, so a rattle from the cooler area alongside this code is worth mentioning.
Likely causes
Start here
- Intermittent wiring fault · moderate

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.
