I have a 2008 Ridgeline and ’m getting a P2413 code. I’ve replaced the EGR with one from rock auto. I cleaned the ports when I changed it. I was still getting the code so I took it to the Honda dealership and they said to put on a factory one. I’ve done that and am still getting the same code. Any suggestions would be greatly appreciated.

 

If you have a scan tool, not just a cod reader, you can see what the PCM is doing with it.

 

Thanks for the reply. I started checking the wiring and found a place where a rodent chewed through close to the fuses.
