What P0296 means

P0296 is a standard SAE J2012 powertrain diagnostic trouble code with the defined meaning: Cylinder 12 Contribution/Range Fault. 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.
