Default got codes, need some brain power...

ok so as some of you know im buttoning up my 02 wrx/96 legacy swap. we tried to run all wrx wiring and then just splice my connectors on when needed. wrx motor, wrx ecu, wrx fuel pump controller, wrx fuel pump. everything else is 96 legacy(tranny, interior, etc). so my o bd2 connector came in today so i scanned for codes...

P0500 - speed sensor
im using a legacy speed sensor, think we have a missing conection from the speedometer to ecu...could that be part of whats causing it to run in limp mode?

P0183 - fuel temp sensor
i dont have one, only way to fix is add one?

P0447 - Evaporative emission control system vent control low input
what can i do for this, i cant find crap on this code that, that would specifically help me

P1230 - manu. fuel air metering
?...just read something it could be due to something with the fuel pump controller...any other ideas?

P0245 - wastegate solenoid
just searched and found something that said you can toss in a 10k [email protected] 0.5w across the wires? anybody hear this one?

P1400 - Fuel tank pressure control silenoid valve circuit low input
dont have one, do i need to get one?

get access to a tactrix and disable any codes in romraider that are hard to fix, and don't affect anything.

P0245... are you talking about the boost control solenoid?! cause you definitly need that.

P0245 - if that does mean the boost control silenoid, I'm running a manual boost controller so Id just need to trick it I guess

Oh good, once again tactrix cable and rom raider should do the trick, or get a stock one plug it in and just zip tie it to something.

Sounds like you know the problem here.

The legacy ecu got it's VSS signal from the cluster. You need to splice the VSS wire from the wrx ecu to the VSS wire that comes from the legacy cluster.

haha 1 down, 5 to go...thank you

im pretty lost on the P0447 and P1230

seems like P0447 only occurs on wrx's when the wire sheers off the evap canister. so im assuming my issue it the lack of connection to an evap canister. im not sure where to even start with this one

and P1230 im just lost haha
