hey leaver red,
just had my damn CEL turn on once again and I don't think she's turning back off. So I'm ready to bite the bullet and do this damn thing. But to make the shipping worth it from Digikey, was going to order the 500k ohm resistor and additional 20uf capacitor but upon searching, I'm really having trouble finding them, and am getting very limited results and in minimum orders of 100. I just wanna be sure they're AEC-200 compliant like you mentioned, so was curious if you'd be willing to post the part #s to enter into digi key for these extras so if the first combination of 200k ohm res and 10uf capacitor doesn't fly, I can fiddle with the other 2 combos you suggested? Would you maybe get back to me here if you get a second. I'd really appreciate it. Thanks a million.

510k resistor: BC3824CT-ND
200k resistor: BC3256CT-ND
10uF cap: 490-12869-ND
10uF cap (dont remember why I ordered these too): 445-174239-1-ND
500k resistor: 500KAACT-ND
22uF cap: 490-12870-ND
That is what I ordered (didn't use all of it). I just checked, and all of this stuff is currently in stock.

No, I wouldn't bother with both the 500 and 510. I just looked at my receipt and copied what I had ordered. I ended up not using a bunch of that stuff. If you search at the digikey site, you can use the filters to narrow down what you're looking for. Just specify the different parameters (for example, capacitors: capacitance, application, mounting type, etc.)

But as I said, the search on that website is pretty daunting to me and the 22uF Capacitor you gave the part# for is only 25V and has a 20% tolerance.
is this alright or do you think I should match them in that aspect and would you happen to have the part# for a 50V 22uF Capacitor?

so you say you don't know why you ordered 2 models of the 10uF Capacitors? Cause after looking at the specifications, they're identical on every single parameter they have listed EXCEPT the spacing between leads being half, the height just a bit shorter, but most importantly, 25V and 50V with only a 10% tolerance. I'd assume just get the 50V right?

If I were you I'd just order a few 10uF caps, 22uF if you want (don't need 50V) and an assortment of resistors (maybe 100k, 200k, 300k, 400k, 500k) to have on hand. I would start by trying the 10uF/200k combo and see what happens.

Since we're only dealing with about 1V here, 25V or 50V doesn't matter. I probably orderd both models because a) they were cheap b) one might fit where I wanted it better than the other.

I'll do my damnedest to find those resistors but might be coming back here for some part #s. :/
edit:
I've found most of them. 300k is a bit difficult as I can't do d one with the aec-q200 rating.
is 1/4w (0.25w) just what you had picked for no real reason or is there any reason they can't be 1,2, or 3watt?

I promise this is the last time I'll bug you about part #s and get them ordered if you could just reference the 100k, 300k .& 400k ohm resistors with that AEC-Q200 feature..

I really hate bugging you, man...

We have finally done it!

Any ideas?
also +1 for Wagos. If you've never used them, I highly reccomend you do.

The URD was never an option for over $100 ide rather deal with my check engine light. have you tried the other methods other than the one you posted and had failures?? I ended up basically doing something similar to the info. on the site Millball posted but I used the diagram off of this site: http://www.sr20-forum.com/general-ma...o2-sensor.html
However I followed the actual diagram on that page and not the posters method shown in the pictures. I reset the ECU so I will let you know if the CEL stays off for good

I have the dreaded P0420 code and it is not the best time for me to be replacing cats..... Can you send me a wiring diagram of the mod ? Thanks in Advance The link you provided above contains photo bucket pics that are no longer good. I feel like this is a much better solution than cat replacement (at least temporarily) which brings me to my next question.
Thank You
Best Regards,
