Hey everyone, I am getting the 1676 and 0401 CELs and was wondering what the fixes are for these.

I tried one of those fuel system cleaner things for the p0401 (EGR valve) code but I doubt that that will fix it.

Thanks!

 

You have to remove the upper intake and manually clean the ports out. Look in the DIY thread for instructions on cleaning it

As for your other code?? it sounds like there may be a short in a sensor or the wiring between the trans and the ECU

 

I found this: http://www.in.honda.com/Rjanisis/pubs/SB/B00-004.PDF but it's hard for me to figure out stuff without actual pictures of the components.

and there was another thread that I found but all the pictures were missing so it was useless. Is there any other DIYs that have pictures floating around?

Thanks!

 

Its the upper Intake Manifold. Its what you see when you open the hood. You remove teh plastic cover and its under that.

What year do you have?

I have a 99 TL-P

 

Look at the link above your post

 

wow took off the IM and looked at the EGR port and it was completely shut with gunk. Cleanin it out now and putting everything back. thanks!

now to just figure out which wires are out of place...

 

hmm, the 1676 code went away but the 0401 code came back on. maybe i didn't clean it well enough or maybe it's the physical valve that's clogged. where is the valve exactly?
