Frequently Asked Questions

What does P2463 mean on a Hino?

P2463 means DPF Clogged. Set when a manual (parked) regeneration request is not completed: the ECU's calculated soot load has reached the warning threshold of 5.0 g/L and the DPR manual regeneration was not performed or did not finish.

Is P2463 a Hino-specific code?

P2463 is an SAE-format powertrain code, but the title and the conditions here are Hino's own, read from Hino's service documentation, not a generic definition.

How Do You Diagnose HINO-P2463?

  1. Check for burner-related codes P2431, P140D and P140E and fix them first.

  2. Confirm the DPR light works with the key on, engine off.

  3. Perform the manual regeneration with the vehicle parked and the engine at the required speed.
