p1109 = Intake air temperature (IAT) B sensor intermittent,
p1108 = EDC15C2 - Fan high speed circuit. Open circuit or short circuit to earth.
p1606 = ECM control relay O/P circuit malfunction
IAT sensor is in the Maf so if its drunk water its probably fobared
the ecu monitors the relays for the fans so if the relays ar missing there will be a fan fault logged
diag reading gear will show a MAP sensor reading but you will find it is a set point and do's not vary
