I am trying to test my turbo control solenoid, the one that is located on
the ACV. Does someone know the spec's for testing this solenoid?
i.e a,b,c, port flow patterns with and with out 12 volts and resistance range.
In my Mazda service manual page 119 refers you to page 190 which refers you to page 121 but page 121 is about the air pump.

They meant to say page 191. I was just looking at that page last night too.

 

FDeez,
Are you sure the spec's are the same as the rats nest solenoids?
If this is true which pipe is a,b, and c?
The turbo control solenoid that is located on the ACV is a completely different
looking solenoid. I believe the TCS the 3rd from the front on the rats nest controls
pressure and the one on the ACV controls the vacuum side of the TCA.

 

The bottom nipple can be blocked off. Test it like the wastegate/pre-spool solenoids.

 

I am ressurecting this thread to find out does anyone know the values of testing the Turbo Control Solenoid on the manifold, next to the ACV. The solenoid that controls vacuum? Anyone?

 

sonix7 Just so you know my TCS on the ACV didn't even pass the 12 v click test, so I knew
it was bad and I replaced it. My turbo problem was different from yours. I have been following
your other thread. My secondary turbo wasn't coming online after transition in 1st or 2nd gear
but would come online in 3rd. My primary turbo was working as it should.

 

I figured out my Mighty Vac was messed up. I took it back got a new one. About four out of twelve solenoids failed both hot and cold tests for 15lbs boost pressure. Luckily it was not the turbo control (vacuum) solenoid or the turbo precontrol/wastegate solenoid.
