Of course you won't get a cel for the p0401 that is checked, but it will show up on a scan.

They plug in their tool. If all the monitors but one are ready and no cel... You pass. Drive off and take out all the random parts hanging out in your engine bay. The end

I got the "CAT" to turn to ready today, but popped a P0421 cel too : / Back to trying the extender I guess

P0403 is because the valve is disconnected.
P0401 is because the valve is not flowing.

Connecting the egr and enabling p0403 will let the system get ready since the valve is there
However because 0401 is still disabled, you won't get a cel that it is not flowing.

I fucken passed emissions this way.... Wtf

Alpha drive around a little more and see if it gets ready and clear this up for us.
Ok will do, thanks

Gonna try the secondary extender to slip by with just the EGR not ready. Do you know what codes need to be enabled/disabled to get the CAT into ready state?

I threw the P0421 today : /

I'll tell you guys till I'm blue in the face. You're not going to set any ready monitors by checking codes. All you're doing is eliminating the cel for those codes.

Update: These cars will NOT go into ready mode unless the associated DTC is checked and active. I put the extender on the secondary cat with the P0421 unchecked and nothing for days... I then checked it and the CAT became READY within 5 minutes of driving. :bigok: Thanks again guys and hopefully this helps some people!

I had my code for primary cat slow to temp unchecked before the car went away for winter, and the codes were there when scanned with the AP.
My txs dp had a built in extender.
When I put the battery back in in the fall to get my e-test, nothing with the map changed.
I drove around for a week to set the drive cycles and kept scanning for the cat codes, but they never returned.
Got my e-test and passed.
