Q: What does code P1443 mean?

EVAP Purge Control Solenoid 2 Circuit Fault. P1443 on a Mitsubishi means the engine computer has detected an electrical fault in the circuit for the second evaporative emission (EVAP) purge control solenoid, which is the valve that meters fuel vapor from the charcoal canister into the intake. The computer monitors the solenoid's command wire for expected voltage or current behavior and flags the code when the circuit is open, shorted to ground, or shorted to power.
