Wow. It just hit me that I've been checking the wrong connection this whole time.

So Uhhhm...Yeah. Feelin' like a dipsh*t.

 

I just shouldn't be allowed near an engine bay. That's the lesson I've learned here.


Actually not really. What I have taken from this is that even when you think you've done something correctly, it always pays to double and triple check yourself against a good source.
As much as I'm embarrassed to say it, I've been looking at the TPS this whole time, not the IACv sensor. Wanna know what's even worse? The IACv harness wasn't even connected. So I connected it right up, and the problem was solved and the CEL, once deleted, hasn't come back! Finally. A successful intake manifold gasket change!...It only took 3 days too! Ha! :P

Well, thanks a lot for your help! Made life much easier. And, now I know how to test my IACv if and when it goes bad!

Now I've just got to find out why this pesky SRS light is on without throwing any kind of code...

 

Good to hear the other issues are fixed.

For the SRS, the OBD reader/scanner needs to be capable of reading Honda ABS/SRS trouble codes. A lot of OBD readers/scanners don't have that capability. For example, an Innova 31603 has such capability.

There is another way to retrieve the SRS trouble code by jumping a connector. The instructions should be somewhere on this forum or the web.

For the 6th gen Accord, IIRC, common cause would be seat belt buckle or OPDS unit.

 

Here's a video on how to retrieve the SRS trouble code without a scanner.


You would jump the DLC cavity terminal 4 (Blk wire for Ground for PGM) and terminal 9 (Brn wire for Service Check Input) with a small wire or paper clip.

 

Yeah, my Actron doesn't seem to have that functionality unfortunately. But I'll see if I can find those instructions you mentioned!

From the couple searches I've done so far, it looks like you're right about the seat belt buckles. Which would be nice because the seat belts are under warranty for the "useful life of the vehicle".

Edit: Just saw the vid. you posted! Beautiful!

 

Glad you got it.

Don't beat yourself up too bad - we've all been there at one point in time.
