CARspec encountered a known issue with the 2005-2008 Toyota Corolla and Matrix today and wanted to share it, hopefully preventing a costly repair for an owner.
If your 2005-2008 Toyota Corolla or Matrix (FWD) was in for an ECM replacement recall AND you have code P0741 (Torque Converter Clutch Solenoid Performance) there is a chance the wrong ECM was installed during the recall. The ECM differs if the car has Vehicle Stability Control (VSC) or not, the part number differing by a single digit. This code in particular (and no others) is a known consequence of the wrong ECM being installed.
For this particular failure CARspec is happy to check for the correct part number before charging for diagnostics. We hope this helps an owner get their Toyota repaired at no cost!
I have had my ECM replaced on my 2005 Corolla and have had several problems with my Torque Converter. The CEL comes on periodically, but never stays on more that a few days. I have the p0741 code. Is it possible the wrong ECM was installed? If so, what are my options? Any recalls for torque converters for my Corolla?
Pete,
There is a chance the wrong ECM was installed. If possible, ask the dealership that replaced the ECM to verify the part number against the bulletin for your particular check engine code – they should be able to look it up on Toyota’s internal technical network. There is a good chance you do have a failing torque converter, but checking the part number is the first step.
Good luck!
