Question

I recently had the shop replace the fuel filler neck, and the knock sensor. I drove about 3 miles and the light came back on

Answer 1

P1446 Evap canister vent control valve closed

P0400 Exhaust gas recirculation flow malfunction

P1441 Evap system flow during non-purge

P0325 Knock sensor signal

The vacuum hose connection and its routing has to be checked, P1441 is set when there is small evap  leak , The charcoal coal canister that should be check for leakage itself this is common code , when P1446 is set it always the first component to check
