A friend of mine with a 2005 Matrix, 160k miles, got a bad diagnosis today. Codes p0441 p0455 p0456 p0171 with the remedy of replacing the entire ECM and associated components for about $1200.
Anybody know if this problem can be resolved with a simple ECM swap or if there’s more to it? Seems it a common issue (see TCB here - http://www.toyotapart.com/M.I.L._ON_DTC_…) and the official Toyota remedy is a new ECM.
Just wondering if any of you good folks had a suggestion other than raiding the car repair savings account.
