Hi all. I'm a long term 2011 Evo X owner (Bought it brand new) and have been running ETS boltons and a CBRD BorgWarner 7163 turbo kit for about 6 years now tuned on a CobbAP. I've largely had no issues when it comes to the tune, throwing DTCs, etc. I recently decided to switch to ECU Flash and do some remote tuning. I'm in the beginning of the process tuning but have been throwing a P20A0 DTC after about 20 or 30 miles (I cleared the code once before). Never saw this when I was tuned on the CobbAP as a reference point.

From what I've found, sounds like this could be related to the PVC valve. Aside from making sure the PVC isn't clogged or stuck, has anyone ran into this and/or know what could be the cause here? I'm tempted to reflash on the CobbAP and see if this comes back. Thanks!

 

I happened to have a PCV valve that I bought a while ago. So I replaced it based on the DTC details my tuner sent:


Will see if this happens to be the issue as the PCV valve is original and I've read are prone to failures.
