I hope someone can tell me if evap code P0440 will reset without clearing all the OBDII ready codes first? My vapor canister vent valve/solenoid had a broken wire at the connector so wasn't getting power, this threw a "service engine soon light" of course. I would really like to avoid the complete drive cycle ritual if possible. The vehicle is a 1999 Isuzu Hombre (same as a Chevy S-10), 2.2, 5-speed, RWD, Pickup. I can reset the computer if I have to but it takes looong time with a lot of driving to get everything ready to test the evap part.
