Mazda part number for solenoid valve turbo control
 

Does anyone know the part number for the solenoid valve (turbo control)? This one is bolted on at the top inside of the LIM and not in the rack.

Thanks,

This one in the center of exact center of the image near D-code 13-940? That turbo control valve comes only with the pipe. About 400 bucks too.. Part number N3C1-13-36Y

Toadman, that's Charge control valve not the turbo control solenoid. The TCS#1 is located on the LIM on top of the ACV. Sorry don't have a PN though.

hmmm... pic one from the rat's nest then... :)

that isn't it.
 

I tired to send a photo but can't get it down to an acceptable size. The solenoid is on the inner side of the lower intake manifold. It is mounted with one bolt and it is not on the solenoid rack.

one more try at a pic
 

this is it.

Ok, pretty sure I found it. :) Look at D-Code 23-7251, part number N250-20-725, about 64 bucks. If not it, PM me and we'll go from there isntead of burning up eveyone's bandwidth. :)

That's it!
 

You got it that time. Thanks for the help.

I'm confused.
The number 23-7251 is not the turbo control solenoid. It is the Split Air Bypass solenoid. The turbo control Solenoid (Vacuum side) is the 18704B on this picture.

There are two solenoids for the turbo control. The second one (Pressure side) is the third solenoid on the lower rack from the front of the car. This is the same solenoid as the rest of the solenoids on the rack and can be interchanged.

18-740B
 

The 18-740B is what is was looking for. It has a different mount than the ones on the rack. My dealer couldn't find it on his computer. So now with a part number and pic I can show it to him.

Basically I'm replacing all the solenoids along with the hoses since I have the thing apart. I had several cracked or nipples broken off so I might as well replace everything under the extension manifold and solenoid rack.

Thanks,
