EGR Position Sensor
Reports how far the EGR valve has actually opened, so the module can compare commanded position against real position. That comparison is the most useful single test on an electrically actuated EGR system: a valve binding on carbon moves slowly and incompletely rather than not at all, and only the feedback signal shows the difference.
Also known as: egr sensor, egr valve position sensor, egr potentiometer, egr feedback sensor

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.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.
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.
