Emission Problem

[Disturbed_beast]

I have not been on the forum for a while becuase my transmission went on my legacy. Although now that my car is running once more i have some problems that i need help with. Now if anyone could help me with some Check Engine Codes that with be great. I know what they mean, just need to know what parts i need to fix this problem so i can pass my emissions test.

Here are the Codes:
P0453: Evaporative Emission System Pressure Sensor/Switch High
P0546: Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 1
P1086: Manufacturer Controlled Fuel and Air Metering and Auxiliary Emission Controls

Also i have done a 2002 WRX EJ20T engine swap to the car

Did you have the problem before the swap? How long as it been since the swap? Was everything wired up correctly when the swap was done?

(oh, and the 02 WRX is an EJ205. EJ20T is a mis-used term, and is NOT an actual Subaru engine code.)

Wild guess from me: 1st & 3rd codes = WRX fuel sensors in the tank aren't hooked up.

2nd code = a similar problem, has to do with an additional sensor the WRX has for the EGT?

Holy shitballs, it's a ghost.

Glad to see you your still in the Leggy!

Not that I know much about swaps, but Huffer's explaination sounds like a good place to start. Also, you might want to PM xcntrk75, I'm sure he could give you a list of things to look over.

I found out what the code P0546 was and what i needed to do. But the other codes are still a problem in process.
