Review on Enhanced Toyota 90910-12079 Vacuum Switch Valve: Powerful Performance for Optimal Efficiency by Dustin Keller

Revainrating 5 out of 5

P0401 EGR code cleared!

Problem installing @$£ but this part fits my 1997 40th Anniversary Toyota Land Cruiser fzj80 perfectly. After installing it cleared my EGR-P0401 low flow code. Now the car drives much better. Just be sure to clean the carbon deposits while you're there and the intake manifold is disconnected from the MAF sensor. It's a small hole above the air intake.

Pros
  • Hands free operation
Cons
  • Doubtful
