Pulled two codes from the computer last week....
The first code 17522 Bank 1 sensor 2 (internal resistance too high)Replaced o2 sensor
Other code 17819 Sec. Air injection sys. Bank 2
flow too low---Any ideas on this one
Mechanic replaced o2 sensor check engine light went off then returned next morning.
Says to check:
-fuse for secondary air injection pump
-vacuum hoses
-hose from pump to secondary air injection pump
If I change hoses to silicone would that help???
What else should the mechanic test.
Thank for the hlep guys.

Which motor?
In 4.2 world anyway, check all vac hoses. Or best, buy about 15 feet of the 3mm stuff and replace it all. Any quality brand or NAPA. Braided stuff prone to failure after 3-5 years.
