sigh.. CEL

ok, ended up buying a reader (only $59 at AutoZone) and got the codes:

Car Specs:
2000 non-S
no mods
54k miles
oil change 3k miles ago
no other issues with car

Codes are:
0410 and 1411

which appear to be (respectively):
P0410 Secondary Air Injection System - Signal Implausible (Cylinders 1 - 3)
P1411 Secondary Air Injection System - Signal Implausible (Cylinders 4 - 6)

is this an MAF issue or something simpler? I bought maf cleaner while i was there, but would like to not have to dig into the engine compartment if unnecessary.

thoughts?

Same codes I have!!
Look at the post called Help!
You probably need a new air pump valve and new switch.

I erased the codes using the reader and then restarted & let the car run for about 15 minutes (minor revs throughout) and the light did not return.

now, I'm smart enough to know that this didn't "fix" the problem, but has put me at ease for the time being... good to know I can drive with it if I need to as well.

I am taking it in tomorrow for non-related routine maintenance anyway so I will have my guy check it out as well.

*stupid question warning*

would washing the car and getting water in a "no water zone" cause this? I did manage to wash EVERYTHING and probably aimed the hose in some wrong places... just a thought, but curious.

thanks guys

Washing the car won't cause this. Just a stuck valve or a vacuum leak not allowing the valve to fire.

If you happen to change these before me... please take some pics of the job.
Good luck

Could be any of a half dozen things, probably an air leak.

Good flow chart with diagram Mike.

Probably not MAF related. If the problem occurred soon after a little invasive washing you may have gotten the pump or a relay wet and toasted a fuse. Real easy fix. Also check for loose or damaged wiring to the air injection pump. The "signal implausible" term is a weak German/English translation for "open circuit" or "no signal" from the sensor.

Good luck with your fix. Definitely not the end of the world.

was kinda hopin' it was an MAF problem now lol.. seems like an easier fix.. the word "pump" makes me think $$$...

anything I can fairly easily self-diagnose (the fuse you mention) before taking it in tomorrow?

so yesterday i made a quick run to the ice house after clearing the CEL to see if it would come back. when I started it, it BARELY started!!! what the... like OVERNIGHT my car went from fun as hell to omg i hope i don't break down...

so.. i drive it to work today and when i started it this morning, i see this big puff of white smoke! i know i know, but this isn't the normal white smoke, larger puff than normal, and it did the "sputter" thing like it was hunting for the right idle, then it normalized... still no CEL, idled ok i guess.

i've been reading a lot about the different possible causes and what all is involved with replacing certain items. im pretty sure i hear the "small hoover" sound at startup that is supposed to be the air pump, but one man's hoover is another man's "whirring" or "whining" so im not sure if it's the right noise..

How much would a new air changeover valve (exact name?), AOS, and electric changeover valve cost to replace? parts only.

also, i have read that the alternator needs to be removed for the air and electric c/o valve (ugh.. bad memories there) so how many hours of labor would replacing these 3 items take?

anything else I should have my mechanic check while he's in there?
