| Electrical System problems |
I have an 2006 Lexus Gx470 and these lights came abs, vsc trac, vsc off, skid, and check engine. The vehicle started making a humming noise at start up and now drives in stalled mode. Had codes check and it turns out I have the dreaded secondary air injection system (emissions) defect p0412, p0418 ,p1440/p1443, p1441/p1444, p2440, p2445, p1442/p1145 , which is a recurring problem. Replacement is a nightmare for self repair or a $2000+ repair.
