Question type: Maintenance & Repair

1 Answer

Defective Vacuum Switching Valve behind the air intake filter housing fixed problem Replacement of the Vacuum Switching Valve (VSV) that is mounted on the backside of the air intake filter housing solved my EFI fuse blowing problem for a 2001 Lexus RX-300. Look between the Brake Fluid Reservoir and the Air Filter Housing to view the VSV. My problem: EFI fuse blew as soon as ignition switch was put in the "On" position. Seems that when the VSV was energized (which apparently occurs immediately upon turning the ignition key switch to "On"), there was a short in the VSV that caused the EFI fuse to blow. With the VSV not energized, the resistance between the two pins at the cable connector was normal (about 18 ohms as I recall). After five days of trying to fix the problem myself, I took the car to a local repair shop. That repair shop took another five days to figure out the problem. Cost me $600, which was very disappointing as they advertised a fixed price for determining the problem ($125) and would apply that fee to the cost of repair. The final bill was primarily labor to figure out the problem. Replacing the VSV takes less than 30 minutes. Replacement part might be: Denso: Vacuum Valve Part Number: 7880-01183479 Price $50
