Hi all, I have a P1131 code on my 01 pathfinder. I was doing a fair bit of reading on the site, I tried clearing all the vaccum lines etc but it didn't work.

I had to drop my car into the shop for another reason and asked for a quote to fix it. The garage just called me and said there's 3 SVC's in the car and if it's the most expensive part to replace it would cost me about 1000CAD including labor. They said labor would be about 4 hours.

From everything I've read online there seems to be only one SCV? And it looks like an easy job to replace. Can anyone clarify the above? Am I right in saying there should only be 1 and that it shouldn't take 4 hours? Would I be best off just getting an SCV from the dealer and sticking it in myself?

there is a swirl control valve, and a swirl control solenoid

check vacuum hoses near the power valve actuator for cracks and leaks
