I dont know how to discribe this my 2001 wrx feels like its gone in to a limp mode i have no power over 50mph no boost no go at all. There are no fault code coming up, i have swoped maf sensors nothing. l tried the boost solenoid test by connecting the 2 green connectors under the dash. The fans came on and off there was nothing from the solenoid am i on the right track with this?

If its not making a ticking noise , its probably toast

Normally if the ECU has put the car in limp mode it lights up the CEL. Faulty solenoid also usually throws a CEL...........is it a bugeye WRX?

No noises from the boost solenoid then I'd swap that over.........2 port solenoid cheap as chips for the bug as people swap them for a 3 port.

Strange the DENSO ECU hasn't spotted anything ?

Hi i didnt think you got the click from the solenoid in a bug when you join the green connectors,or if your ment to mines toast aswel.

connecting the green connectors on a bug wont work to check boost solenoid. take it off and put an earth and power to it, you should here it click,if it clicks try cleaning it out,if it makes no noise replace it. also try ecu reset,needs to be plugged in by someone with correct software for that unfortunately. its bit weird it has no cel on tough.

My WRX (2003) used to do something similar. It'd go into limp home mode if it had some bad fuel - no CEL, and the only thing that used to sort it was to disconnect the battery for about 5 minutes. Someone else on the forum a couple of weeks/months back had the same issue, and disconnecting the battery worked for him also.

changed the boost solenoid today did not make any difference at all. this has really puzzling me now
