CEL P2227

[Eric R]

Hello all,

I have a 2009 Impreza 2.5i non turbo. Bought it recently used. I was preparing to perform an oil change and started the car to move. 

Bam, CEL of P2227! Baro sensor out of range? So, what to do?

I've checked and cleaned the MAP, checked and cleaned the MAF. Looked for bad vacuum lines, reset ECU.

Only thing done recent was a Battery charge, exhaust pipe work and replaced the fuel pump. 

A previous owner has put in an remote start. Everything else is bone stock.

Not sure what else to check, especially when the service manual says to replace ECU?? Is that where the BARO sensor is?

Thanks 

Eric
