What CEL Codes Would Catless Headers Trip

3002 tii · 11-14-2015, 09:54 PM

For the time being I removed my off road tune and as expected I have a CEL/EML warning with different codes. But I can't tell which codes directly result from headers vs something else going on with the car. Prior to removing the tune I had an Evap related code which I thought would go away (loose gas cap?)but it's still there.

I had a couple of codes when I was running a stock tune with headers. I don't remember the exact alphanumeric sequence, but I think I saved them. I'm currently away from home but will be back tomorrow. Anyway, they were clearly cat-related, based on the description.

When my installer uploaded the wrong tune, I got generic codes P0153 and P0133.

Ok, the codes I had were "29F4 - Cat conversion" and "29F5 - Cat conversion 2."
