ISX 871 error 2449

[Lead_sled]

So, yes, I checked the resistance. 60 ohms.

So, this will probably open to some other issues, but I’ll see where it leads.

When my engine brake is in high position, it’s very effective. But it’s like it takes gulps. Like: rrrrrrrrrrrrrrrrrr gulp rrrrrrrrrrrrrrrr gulp rrrrrrrrrrrrrr

Lol, I’m sure you get the idea.

Prior to the demandate, the turbo would spool up to around 38 psi. However, after the demandate, the highest it’ll spool is 28 psi.

Demandate done approx 90-100k miles ago.

I’ll try to take a video of that gulping action next load I pull. And I’ll video the boost gauge at 28 psi.

Any ideas???
