I have a 2009 Subaru Outback with PSEV on it and I have had the same engine error for four months. The catalytic converter isn’t functioning properly. I took it to my local shop for an inspection and obviously it failed.

They said that typically replacement would be $1800 for a normal converter but because of the PSEV, it’s probably $2800 plus potentially $300 because the oxygen sensors can be difficult.

Does that sound reasonable? Can I replace the PSEV with a normal converter or is that impossible? The guy also said he couldn’t find it in after-market so the part would have to come from a dealership.

Does anyone have experience with this? I’m in NC with the car purchased in CO.
