Error code p1504, what does it mean? I understand that it is something related to the IAC unit but it is not very specific, is there any way to be more specific? Like is it an electrical problem, something mechanical? Is it related to the computer?

Do you
have the same problem?

P1504 Intake Air Control circuit malfunction

Check the IAC but chances are there is a different sensor setting this code. Could be MAF.
