Car safe to drive with these codes?
Hey everyone,
So last night my B5 threw it's first CEL, amazing I know.
The codes ares:
17522 - Oxygen Sensor B1 S2 Internal resistance too high P1114, intermittent
16795 - Secondary Air Injection System: Incorrect Flow Detected P0411
16712 - Knock Sensor 1 (G61): Signal too High P0328, intermittent
The rear O2 I have known for while but that never threw a CEL. I think that the 16795 is causing the 16712 which threw the CEL.
I checked the ross tech wiki and it says:
I am thinking something fuel/air related from the first code is causing the engine to knock and set off the second code and the CEL. Anyone ever deal with these before?
I will go check the fuel pump relay and the secondary air injection relay now.
Any help would be appreciated.
Thanks

The broken pipe can cause the AIR code, but it should not affect the KS or the O2 . The AIR does not affect engine performance and the AIR pump only operates till the cat is lit. A bad KS could cause engine damage, and the O2 could cause economy and performance problems.

the bad secondary wont be anything bad. sensor 1 is the one you need to worry about, although you wont pass emissions with a code like that. it would need to be fixed if you have emissions. the secondary air injection code is most likely because of that broken pipe seeing that pipe feeds the secondary air system. as for the knock sensor code, i got no idea besides a bad sensor, unless of course you have been knocking badly
