What P0672 means

P0672 is a standard SAE J2012 powertrain diagnostic trouble code with the defined meaning: Cylinder 2 Glow Plug Circuit. This is the OEM-agnostic definition; specific manufacturer interpretation may add detail (subsystem, bank, sensor location) but the core meaning is consistent across all OBD-II compliant vehicles since 1996.

Can this code be suppressed via ECU tuning?

Should NEVER be suppressed. Misfires indicate genuine combustion issues (ignition, injector, mechanical). Suppressing them risks engine damage.
