Anyone know how to check my DV's?
I have been dealing with the following codes:
P0492 fault code 208 - secondary air system bank 2
P0491 fault code 80 - secondary airs system bank 1
after much research I see that one of the possible problems could be from the dv's. I have a set of Evoms dv's and after researching about them understand that they can come loose from vibration and might need to get serviced.
How can I check to see if my DV's are secured and check if it is leaking.
The strangest thing is that even after the car warms up and I am crusing on the highway I get this code. I tried to go to do an emissions test by heating up my car's engine, clearing the codes and then driving about 135 miles to allow the DME to adapt. At around 135 miles these two codes showed back up.
Any ideas?
Thanks for your help.

Pull the DV's out and test with a hand pump... also, look over the entire vacuum system as its it relates to the DV's.
