Mad Hatter
Gotta go Faster
Hi, I recently logged mi Boss in hopes of getting a tune from AED. I have been having P0420 powertrain codes saying Catalyst system efficiency below threshold and P2254 Powertrain: O2 sensor negative current control circuit/Open bank2 sensor 1. I had thought they had to do with the Kooks LTH and Cats and could be fixed with a tune.
After reviewing my logs, Shaun made it very clear I have to fix the engine issues ASAP and he would not tune the car. During the logging another error code came up, P0451 Evaporative emission control system pressure sensor range/performance. Fuel tank pressure lower the specified value.
Any incites on where to start? Was thinking I need new O2 sensores, but the tank pressure code is new to me. Taking the car into a shop tomorrow (New shop, old shop just cleared codes).
