What does code P1413 mean?

Q: What does code P1413 mean?

EGR Differential Pressure Sensor Signal Too High. P1413 on Volkswagen vehicles means the engine control module has detected a signal voltage from the exhaust gas recirculation (EGR) differential pressure sensor that is higher than the expected range for the current operating conditions. The sensor measures the pressure difference across the EGR valve flow path, and an excessively high signal typically indicates a wiring short to voltage, a faulty sensor, or a blockage that skews the pressure reading.
