bump.. having the same issue. anyone else fix this problem? if so how..

 

anybody? I will give you $5 and a snickers bar if you help

 

Sooooo..

By searching the **** out of this place and finding both the service manual instructions and suggestions on the ecuflash forum.. I finally "fixed" my cel caused by P0446..

I took out every solonoid and tested it and they were all ok.. The wiring was also good. (service manual has you check these.)

So it had to be the ecu.

To fix this I ordered the elusive and out of stock tactrix 2.0 and used openecu to change the base flash..

I had to set FCA periphery bit 15 to 0 and did the emissions hack found here..

The only problem is that I think it worked too good.. It makes the car pass every test and a talented inspector will catch it.. Per my original inspection sheet the EVO should list the following tests as not supported.. With the hack they came up as "ready"

Secondary Air system - should be not supported
A/C refrigerant - should be not supported
Heated catalyst - should be not supported

Anyway I am back on the road and hope this helps someone with the same issue.
