HI, I own a 1986 4Runner, and I need some help to find this sensor, from what they told and that I can translate its a Mass Air Flow sensor, I could not find it in Mexico, so I started lookin on line but I can't find one exactly like this one. I put a screw where the sensor goes. Could somebody be so kind to tell me the correct part number and where can I buy it.

That is a Bi-metal Vacuum Switching Valve (BVSV). It is a valve that only lets vacuum reach the Exhaust Gas Recirculation (EGR) valve when the engine is warm enough. It is separate from any air flow meter.

I could not find any valve with that light grey color and that part number (25320-13010).

However, Toyota has "updated" this part several times and it looks like the current version is black.

Valve, Bimetal Vacuum Switching, NO.2
Toyota Part Number: 25820-13020

You can find it at https://22reperformance.com/intake-e...witching-valve for 98.76 USD plus shipping, but I bet you can find it cheaper in Mexico.
