so i did the whole tank bypass and all, and was running only one line. from the bypass valve straight to the intake manifold. been running that setup for almost 10 months, as of two days ago, i was just messing around and remove the solenoid as the one show in pictures, and now i'm trhowing a code as "boost bypass control circuit", i try to hook it back up, clear the tune with my code redaer. engine light come back on, try to splice the two wires and connected together, clear the code again. but no luck, engine light come back on again. hook everything back together as the way it was, clear the code with my code reader for the 4th times, the engine light still come back on, please help!!!!


P0033
Turbocharger Bypass Valve Solenoid Control Circuit
ECM
DTC P0033, P0034, or P0035 this is what i got, does it have to do with my soleniod?

 

You need to keep that solenoid connected, not sure why its still throwing the code and it cant be erased, im sure it'll go away.

 

like i can't splice it and connect the two wire together? or leave the two wire not connected? i put the soleniod back, clear the code, start my car, drive it around, turn it off. start it back up, the engine light come back on again. anymore help adive would be nicem thanks.

 

Check this file out. It's a sticky in the LNF section. It has all the CEL codes listed: http://service.gm.com/gmspo/mode6/pd...F%20Engine.pdf

Looks like an electrical problem, but not necessarily with the Boost Solenoid. You may have a short somewhere. The CEL comes on based on failing an electrical system continuity check.

 

Yep, I'm not sure what else it'd be but it might be something else in the circuit. Maybe the other end of those wires. I went through this with my MAF. Broken wire in the plug. So it may only be coincidence that it occurred when you did that. Just like my MAF problem, it was only coincidence that I happened to have cleaned the K&N filter that night but it had nothing to do with it. So like Stamina said, it's failing a system check. Might be a broken/loose wire somewhere, perhaps further down into the wiring.

If you can, you might have to see if you can get some information on the pins and start doing some continuity checks, voltage checks, etc....

 

a short? so it could be a fuse too?

 

Hell no, why would you want to do that, you'd probably create more damage that way. Try a different code reader and connect the solenoid back up.

 

okay, put the soleniod back, reclear the code. no more code, yeah. thanks everyone.
