CELs and problems, help?

[MelloEclipse]

So basically i think my car is falling apart...i have the following codes thrown

P0125
P1103

I know the first is 'probably' my front 02 sensor from what i've read.

As far as the 2nd one, i'm kind of at a lost for what it really means. Also, which i think is related...my turbo seems to have basically quit working. It builds boost and vents through the 1g BOV fine, but it has no power whatsoever, So it leads me think that my wastegate is screwed up?

What do you guys think of this?

I'm not familiar with the codes off hand. If you could tell me exactly what it reads out for P1103 I may be able to help you. As far as the boost problem, always always always start with a boost leak test. You can fab one up or buy one. Most likely you have a leak that you can't see.

P-1103 is described as turbocharger wastegate actuator malfunction. P-0125 is Insufficient Coolant Temperature for Closed Loop Fuel Control(possibly a bad thermostat).

You can fix 'P0125' by changing the o2 sensor and coolant temp sensor.

if my wastegate is malfuctioning, would that explain my p1103 problem, along with my the boost problem as well?

DEFINATELY

 

[MelloEclipse]

sorry if i sound like an idiot i'm just way out of the loop these days

 

[da_golden1]

do you have a boost controller?

 

[MelloEclipse]

Yes and it's not working, it doesn't controll boost no matter were it's set, and the spring is fine on it, so i actually removed it and capped off the nipples, but still no controll over boost and loss of power, so yes i assume it's wastegate? should i just replace it?

 

[snowborder714]

So your nipple on your wastegate is capped off??

If this is true, then no wonder why your wastegate isn't working. If you remove the MBC, you need to run a line from the wastegate nipple directly to a boost source (compressor housing, j pipe, etc.), not cap them off.

 

[MelloEclipse]

no my nipple on the J-pipe is capped off, but the wastegate doesn't have a nipple that i'm aware of? It's an 16g ...and i think possibly the flapper is stuck open?

 

[snowborder714]

Your wastegate will have a nipple. Look at the picture below and compare your turbo to this one. The nipple on the 16g below sticks up off the wastegate (which is at the bottom of the picture).

You must be logged in to view this image or video.

Run a vacuum line from there to the nipple on the j pipe. This will force the wastegate to open around stock boost (8-11psi or so).

 

[MelloEclipse]

AH excuse my retardedness, i knew that...

anyway, even without the MBC and a line run from the j-pipe to the wastegate nipple, it still builds uncontrollable boost...
