Two DTC's P0412 and P0740
Alright so I went to one of those expensive shops and had the car scanned, it came up that the AIR pump and valve were bad (along with the ABS problems) so I decided a used air pump would solve the problem. Got one off of ebay that seemed in good order for my S90 and just installed it. Now instead of the 0412 only, I am getting a 0740 code something like TCC circuit fault. Any ideas what these two together mean???

Sorry no clue. I was getting a P0420 or P0430 for about 2 months and cleared it one day and it has never come back.

I took mine to a shop and they said that the AIR pump and check valve were not operating (causing the 0420) so I replaced the pump and check valve with used ones (b/c they are exorbitant anywhere else) and now I have the same issue +1.
Does anyone have proper wiring diagrams for a 97 S90? I could troubleshoot this damn thing if I just knew what I was looking for. |
