The other day, I started up my 04 s2k and drove it around as I normally do. Once i parked it and turned off the engine, a mechanical whirr sound remained on. I tried to locate the sound and i found it whirring near the front of the car. The whirring stayed on for about 5 minutes until it sounded like it died (i was freaking out at this point). So i contacted my friend and found no issues with the car as no check engine light turned on. The sound never came back on and so i shrugged it off hoping that it was an outlier of a problem.

On the next morning, my CEL light turned on and I went over to my friend's house to diag the problem. A Code P0410 came on (P0410 Secondary Air Injection System Malfunction) which indicates that the air pump is having an issue. The only mods that I have recently put into the car is a FIPK intake system and the vacuum lines were installed on correctly. According to other members, if I installed the vacuum lines incorrectly, it would throw a P0411 code.

Anyways, using his OBD scanner, we then went on to check the voltage on the relay and the pump. The relay seems to be working just fine sending a voltage to the pump but the pump is shot. The pump is reading a -0.1 voltage reading on a cold start.

My question to you is, which would you rather do...
1) buy a new air pump and stick along the lines of OEM OR... ($850-900)
2) buy a air pump delete kit from izze racing and walk away from OEM as i have to cut/tap into oem electrical lines. ($80-100)

Does anyone know the pros/cons of doing this delete kit. The only two pros i see is 1) I dont have to replace oem parts in case of possible failures, and 2) weight savings and the only pro i see is that I could potentially hurt my cat in the long run.

This really sucks as my plans for (1) cat (2) exhaust (3) suspension (4) sways (5) wheels (6) OEM trunk lid spoiler has to be put on hold as I have to pay for the OEM parts.

 

i've had that kit on my car for a couple years now i think, no issues, wasn't hard to install at all, I'd go with the kit and forget the air pump totally.


its just going to end up dying again down the road eventually

 

1) If you have to go this route, buy used. A lot of people dump the air pump so you can find them fairly cheap.
2) Kit works perfectly and isn't that hard to install. If you aren't comfortable with soldering, have someone do it for you - max 1 hour labor. I just left all the old parts installed so it looked OEM, no issue with inspection/emissions.

 

Sounds like your air pump relay got stuck and consequently, your air pump overheated & failed (the stator is probably melted).

A sticking air pump relay is a common problem, in fact, there's a service bulletin for this:


Like Nate said, buy the air pump & relay used NOT new.
Go whichever way your most comfortable with. Removing the air pump does not effect the lifecycle of the cat, it will just take longer to warm up.

Thanks for the reply. i'm glad to know that the izze racing air pump relay kit works.

Thanks for the reply! I guess the kit isn't hard to install now that squeeze connectors are now included.

THANK YOU SO MUCH for the bulletin. I guess I know that this was not caused by me or previous owners. I am assuming that that's exactly what happened... It threw up two of the codes mentioned. P0410 and P2245 both indicated that the air pump has failed.

 

anyone know where the air pump relay goes?!

 

It's located right next to the air pump, under the driver side headlight. You'll have to either remove the front bumper or partially remove the driver side fender liner. Removing the bumper will give you the best access.

 

Where can I find the kit? Mine just went out and I just wanna get rid of it all together.

 

Google izze s2000 air pump delete and you'll find it
