Need help identifying part on 99 ES300
Does anyone know what these sensors are? They're off of 99 ES300. One of them was broke when I tried to removed it.
Pic taken from the front. You can see 2 small tubes running to one of the sensor. This is the front one isn't broken, you can see the orange plug toward the rear on the right side that is broke.
Rear sensor that is broken and need replacement.

It's a vacuum switching valve, best to seek one out at an auto wreckers new they are $130+. Both are the same BTW.

Just got it from ebay for $21shipped.
thanks guy. I was in the process of changing out #3 and #4 coil, and broke the the vaccum switch trying to remove the hose. I didn't have to remove the intake manifold to swap out the rear coil. I might just replace all the spark plugs this weekend too. I should have the car back together this weekend.
