engine code 31

[saltydog]

Sometimes my check engine light comes on. I found the code to be 31. I switched out the wastegate solenoid, but the check engine light still comes on with the same code. Do I have a defective wastegate solenoid or is it something else?

You just have a blown fuse. I beleive it is a 10amp ATO marked sol on the fuse block.

Do a little searching through the archives. Several things come off the ecm/sol fuse. Apparently a TCC solenoid wiring problem is a common cause of a code 31, a lot more common than a wastegate solenoid problem judging by the posts in the archives.
