P0234 Help!
 

Haven't changed anything on the car in a long time, went wot and noticed boost spiked to 30 and held there, shortly after got a p0234 code for over boosting. Can anyone please help and direct me in the right direction to get this fixed. Thanks

Any help?

Well you are going to set that overboost CEL at that psi obviously.

Is it repeatable?

normally im at 22 psi, not 30 lol not sure why all of a sudden it changed. Ive had the same tune for about 3 years now and havent had any issues with it, so i know something els eis wrong just not sure what.

Any ideas? really would appreciate some help. Thanks

Maybe something happened to ur wastegate, nut moved or something

Went to a local dealer and they said its an internal issue with the turbo, what do you guys think?

Possible, but not necessarily the fix. Are you still under warranty?

No longer under warranty, 105K miles :(

just got codes P0011 and P0010 which are sensors that need to be changed, is it possible these bad sensors are causing code P0234?

I wouldn't think the intake and exhaust actuators are related, but that's a great place to start. Can get those on CED, amazon or from the dealer.

Easy change too

I had an issue a while back with the wastegate solenoid sticking due to oil getting blown in there and gunking it up. Perhaps you have something similar going on and you may need to spray some MAF cleaner through it to clean it out.

I just changed the Evap solenoid and now every time i turn my car on I get p0010 after I clear it. Before changing the Evap I would get the code maybe once a week. I'm changing the camshaft position sensors tomorrow hoping it'll fix everything.

P0010 is for the camshaft position actuators. Change them

I am when I get home today, my question is would the sensors being bad cause my overboosting issue?

Not likely, they are a common failure point.

What mileage are you at?

Op said 105k. I had to change mine at 70k. Easy fix tho

thanks guys, it looks like an easy fix, im still puzzled about the over boosting issue. im not getting any other codes besides the p0010 now

Did it spike to 30 just that one time?

no it happens all the time and it holds 30
