Need advise regarding cause of CEL codes

[BoxsterSenior]

Just recently the Check Engine Light came on by 2001 Boxster S. I plugged in my Durametric reader and the following (3) codes appeared……….

P0430 Porsche code 45 Cat conversion bank 2 / exceeds limit value

P1411 Porsche code 208 Secondary air injection system Cyl (4-6)

P0410 Porsche code 80 Secondary air injection system Cyl (1-3)

Can anyone tell me what failure would cause these codes to appear?

I suspect O2 sensors ????

The following are the O2 sensor resistance readings………

Bank 1 ahead of CC: 128 Bank 1 behind CC: 384

Bank 2 ahead of CC: 64 Bank 2 behind CC: 265

Can anyone tell me what the baseline reading should be?

Thanks!

None of these codes point to a an O2 sensor issue.

You need to fix the secondary air pump - it likely not running (hence the P0410 and P1411).

Check the fuse, relay and wiring (could even be un-plugged).

Then clear the codes and see if any come back.

Loren, thank you for the feed back information.

With my Durametric, I believe triggered the secondary air pump (sounds like a vacuum cleaner) with the Durametric drive links. Does that indicate the fuse and relay are functioning?

I have cleared the codes and driven the car two different 10 mike trips and the codes (so far) have not returned.
