I was advised by another member here that in order to clear this CEL error, I need to check p0420 in Ktuner disables and flash it. I did that, and the error is still there. Would disabling p0138/139 resolve the issue? I didn't want to flash it without knowing more about it. I'm getting desperate and any help is beneficial. BTW, the DP is RV6 catless. Thanks

That was all that I did. I assume that you drove it around a bit too? Not sure how long it took to clear for me.

I thought it clears right away. I will check it out today, since I only started the car and drove a couple of minutes back home.

After flashing the ECU should be reset. Disabling P0138/9 shouldn't hurt anything. However it sounds like flash didnt take. Be sure to open you existing tune file before disabling and flashing.

I flashed it a second time, disabling p0420 and p0138/9 and it solved the problem. Thanks.

It's important to flash each of those when a defouler is in use. :thumbsup:

Cool, wish I knew that before the initial flash. I was all freaked out why it didn't work. I could not flash again for a week since it was a borrowed laptop and I had to give it back.
