P1405 Hyundai Code - Catalyzed Particulate Filter Permanent Regeneration
Quick Answer
Differential Pressure Sensor (DPS) is a piezo electric type of sensor. Common causes include Dropped regeneration efficiency, Clogged Catalyzed Particulate Filter (CPF), Faulty Catalyzed Particulate Filter. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1405 Hyundai Description
CPF regeneration: When a vehicle is in steady speed condition and above normal engine loading condition, if differential pressure between before and after CPF is above the specified pressure, ECM considers that stored soot inside of CPF is excessive. In this condition, the exhaust gas temperature is raised by post-injection 1 and 2 to warm CPF up to 550~650. In this elevated temperature, soot inside of CPF burns up naturally and this mechanism is called "CPF regeneration".
Most of the soot is burned up during the regeneration process but a little amount of soot is not burned up and stored inside of CPF continuously. The stored soot decreases the efficiency of CPF slowly. DPS corrects CPF regeneration period and duration by comparing and calculating the differential pressure due to stored soot with the total distance covered.
The Diagnostic Trouble Code (DTC) P1405 is set when regenerating duration lasts more than 600 sec. This code is often because normal regeneration was not performed as the vehicle had driven in the city.
