Review on 🟩 Aisin VST-001 Green Bulk Vacuum Switch Valve by Brockington Zuniga

Revainrating 5 out of 5

Fixed Code P402 in 1999 Toyota Tacoma 2.7L

I have a 1999 Toyota Tacoma 2.7L with a persistent code P402 and sluggish acceleration. I tried a few different things that didn't work, but this vacuum switching valve solved the problem immediately. The part is light enough to be swapped out for independent work. The VSV is bolted to the intake manifold. It's a little tight in there, but straight ahead. I removed the wire harness bracket to make room. An easy job, maybe 15 minutes not counting the time it takes to find it and remove the electrical plug.

Pros
  • Vacuum Valves
Cons
  • Available in White Only
