P0412 oxygen sensor?
 

P0412 Secondary Air Injection System Switching Valve A Circuit Malfunction
listed under emissions codes

my guess oxygen sensor
anyone else have that before?

Sounds more like the air pump shut off valve to me. O2 sensors usually show as P01 codes. Need Year and Engine size.

ok i'm pretty pissed right now,
i did more searching and found: P0412 code = An open or shorted condition detected in the secondary air (air switching/aspirator) solenoid control circuit.

so i check all hoses, took off airbox, the secondary air pump, blew in it, etc, all fine, i check the vaccum hose, all good, then i take the engine cover off, and suprise suprise
solenoid wires chewed!!! that f***** rat/mouse got in there again
there's new foam from engine cover freshly chewed (new color) from last time it happened, and looks like chewed the 2 wires going into the solenoid.
i'm pretty pissed (last time it was a vaccum line that got chewed, now this).

i better start parking in the garage at night, warm engine, cold weather, attractive for rats/mouse
time for some poison, grrrrr

excuse the cellphone pics

freakin uneeded projects

hehe I would not have guessed that one. Glad you found it.

What's the OBD II P-code for rodent damage? :rofl:
Glad to hear you found the problem. You need this BMW retrofit: 82 10 9 416 945 Marten Repeller Retrofit. It's for an E46 but I'm sure you could make it fit an X5.

thanks Rayxi, i remember now where i saw the kit, on e46 boards, but who would have thought it'd actually happen in real life hah
lol thats funny retrofit, i will definitely have to check that out
because whatever roddent is there might still be around
my rottweiller was going around the car last night sniffing at the wheels,
there was definitely something there he kept going in circles around the car looking for it lol


here's my enemy lol

time to empty the rat killer shelf on any store that i see
grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rr

That sucks! Calls for some rat poison. Putting it in the engine bay should ensure no neighborhood cats or dogs get at it.

lol it's war now, i ordered traps, poison, and more traps :mad:
