What P2145 means

P2145 is a standard SAE J2012 powertrain diagnostic trouble code with the defined meaning: Exhaust Gas Recirculation Vent Ctrl Circ High. 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?

Very common service. EGR mechanical failure (sticking, carbon buildup) often pairs with ECU-side EGR off. Off-road or motorsport only.
