Ok.... I started taking stuff off and testing parts of the turbo system.

I got to the wastgate control actuator and followed the direction on page F-90 in the shop manual it states

Verify that the actuator rod is moved when applying pressed air pressure to 69-98 kPa.

I hooked up a vacuume pump to the blue nipple circled (in the picture below) and pluged the green nipple circled (can't see but it's there) then applyed up to 90 kPa and the rod (red circle) DID NOT MOVE.

Could this be causing the 0-0-11 boost pattern? or am I doing somthing wrong? I don't know much about the wastegate and how it works

Everything worked fine before I tore down the motor. Is it maybe just stuck and I need to jar it loose?



Thanks in advance,
Chris...

 

I'm stuipd.... it's not vacuume... it's pressure. I did a dif and it moves

What should I be looking for? all the hoses are correct... the pills are in correct.... hmmmmm

 

Check the waste gate and pre-control solenoids by applying 12 volts to them. You should hear a click and you will be able to blow air through the nipples.

Make sure the harnesses are not crossed on these same two solenoids.

Take a peak at your turbo control actuator and make sure it is operating and not stuck in the open position.

 

Checked the pre-control and wastegate solenoids... they are fine. I checked all tthe vacuume lines that go to them and go down to the turbos and their parts. Those are all correct. Only thing I have not checked is under the UIM itself... I have a feeling that is next. I'll have to rip that baby of again and check every single hose and wire. Probally have to test each and every solenoid also.

O and.. yes I painted those harness going to the precontrol and wastegate because they looked exactly the same.

Thanks for the suggestions... I'll prob jack it up too and check the TCA also.

 

Did you check the precontrol actuator itself? Its located on top of the Y-pipe. The little rod should be extended with the engine off. In this position, the flapper valve separating primary & sec boost is open. When the engine is started check to make sure the little rod retracts. This closes the flapper, separating pri & sec boost till 4500 rpm, ensuring sequential operation. I had the same problem, the precontrol solenoid was bad.

 

The thing sitting on TOP of the y-pipe (on the back half) is the Charge Control Actuator... it says it's suppose to pull the rod into it when the car starts. Is this what you were refering to?

I did check it w/ a vacuume pump when I was checking stuff and it works... but I did not check and see if it retracted when the car started. I will check that tommorw. Thanks.... if it's not working it might be the charge control solenoid.

 

Ok... I just checked the charge control actuator... and it is NOT going in when the car turns on. So that seems like it's probally my problem (or part of it) in the manual it says it's either the pressure chamber, check valve going to the pressure chamber or the soleniod. Sooooo..... in the next day or so I'll test those things and hopefully I'll be back to normal in no time!

Thanks again everyone for the suggestions.

 

I told you it was the CCA, but you wouldn't listen...

I stand corrected. Sorry, too many damn actuators & solenoids & **** on this turbo system, yes it is the CCA I was referring to. Glad you found the problem. Now just to find out why it's not working.

 

ya ya ya
I'm silly and didn't re-read the thread when I actually went to check stuff out and checked the CRV instead of the CCA

Once I found it was the CCA I looked back at that other thread and went

Would have saved myself the hassle of checking the other stuff (but at least I know they work now too

Time to check the vacuume chamber, check valves and the charge control solenoid.

 

Good luck. It's probably just a kinked or misplaced hose. You really only have a few more things to check and you should have it nailed.
