INSPECTION PROCEDURE
HINT:
If DTC P0441, P0446 or P0450 is output after DTC P0440, first troubleshoot DTC P0441, P0446 or
P0450. If no malfunction is detected, troubleshoot DTC P0440 next.
Ask the customer whether, after the MIL came on, the customer found the fuel tank cap loose and tight-
ened it. Also ask the customer whether the fuel tank cap was loose when refuelling.
If the fuel tank cap was loose, it was the cause of the DTC. If the fuel tank cap was not loose or if the
customer was not sure if it was loose, troubleshoot according to the following procedure.
