Greetings,
First smog check on an 85 FJ60 to try and get titled in CA . Only failed section was high NOx. The EGR valve and BVSV test good and a brand new cat has already been installed. The VSV does not open at 1,500 RPM but does open when I apply 12v. When above 1,500 RPM is the ECM supposed to send out the signal to open the VSV? I checked the ECM for cracked solder connections but am not seeing anything obvious. I'm still ordering an ECM from Engineer8000 that has tested as good in case I end up needing one. I've also ordered a new EGR vacuum modulator, Vacuum Solenoid Modulator EGR Valve Fits: 4Runner Celica Corolla Land Cruiser & | eBay - https://www.ebay.com/itm/192195496936, I think SpikeStrip provided that link in some other smog post. Any tips on how to find out why the VSV is not opening above 1,500 RPM?
