Very good job man , you briefly broke down 1 million points in a very short time.

Very well explained. Knew all this but it's the perfect explanation for someone that doesn't have this knowledge. Chasing down a p0234 on a 2013 focus ST it's been 5 months and still haven't figured it out but I know how to use forscan now and feel fancy 😂 FYI if you're replacing sensors always use OEM these sensors are very delicate and china doesn't always work

How to tell is wastegate actuator too tight? It has nuts to adjust lenght, I can make it shorter or longer.

I have all this codes P0471, P0380 and P0234 fault codes renault maste, intiallly i used to get check anti pollution system but it used to go awag after high way drives but thos time i got the check anti pollution and check injection when connected with obd2 scanner i got the above codes car drives normal. One of the codes is glow plug circuit I'm not sure if baf glow plug can trigger this lights?

I had this code and changed the solenoid. Never had any sort of lack of power. After I changed the solenoid change the light stayed off. Later on I had a code for my catalytic converter. Ran some cleaner though my system via fuel. Fuel MPG went up after that. Now the P0234 code is back and I am experiencing lack of power on hills at highway speed. Any ideas?

wastegate jamming up. Take the wastegate off and clean it make sure it can move in and out freely. The new sensor has been quick enough to keep the target and actual turbo speed close enough to each other as not to throw a cel but the more jammed up the actuator rod has got the more variation there is between what the turbos being told to do and what its actually doing. The only other thing that would cause that is a dodgy maf. To find out which one it is if you have a scantool even a cheap one you will be able to see maf pressure live and watch it to see it doesnt just hop up from say 0.6 to 3.6 instantly like a spike. If its not the maf then it will defo 100% be the actuator but my bets on the actuator to begin with. If your reader can bring up custom readings then select the following > 1. Maf pressure 2. Waste gate duty 3. Waste gate actual 4. Boost Pressure 5.Boost pressure actual. 6 voltage. What you want to look out for is the waste gate actual and if its varying when the duty goes up and see when you can see the boost spiking above what its been told then have a look at everything else as it does that to see what ones playing up.

I have a 2016 Ford fusion titanium 2.0 turbo I got the P0234 code also with a misfire code for the third cylinder not sure if something with the turbo would have something to do with the cylinder missed fire I could really use the help thank you

The turbo hose is separate. Does this affect the turbo and the P0234 code appears?

I have a 2008 Focus ST with the Volvo T5 engine. I keep getting a p0234 code and car goes into limp mode when I go up steady inclines and have to use slight boost to maintain speed. Doesnt do it any other time, boosts hard and drives perfectly fine otherwise. Any ideas?

jamming up wastegate

@SupremeRC 7 ай бұрын

I have a 2013 Ford Escape I don't know if it matters if it's from Canada or not it was imported sold in the US Michigan the Motor City. I've replaced everything from the turbo to the solenoids to the diverter valve. I still can't find what the problem is. Would it be buying an Amazon solenoid turbo solenoid I read somewhere where it was best to have the Ford product if you're still getting these issues I just don't want to spend $100 for the boost solenoid I have bought three of them now? Any help is well appreciated😊

Thanks for the info, very helpful. Hopefully my problem only ends up being the a bad wastegate on my Land Rover.

I have a 2013 Chevy Cruze. Replaced the turbe a couple of years ago. Today I picked up a PO234 code, and only that code. How would I troubleshoot the wastegate and boost solenoid?

@kristoffer9873 10 ай бұрын

Test the wastegate with a vacum tester. On top of the turbo as in the video the actuator has a hose going in it. Remove the hose and put the hose from the tester. Search up on how to test and you will find a video.

boost solenoid will give wild readings on the actual boost pressure on your reader. Watch the boost and actual boost pressure and if its wandering and overshooting slighlty then you just need to clean your wastegate the rod will be jamming up slightly. Check the maf isnt going nuts on your reader too. Like getting to 70mph or whatever and deciding to spike up.

I got this error too: 16618 boost presure regulatiom p0234 - 000 - limit exceedee (overboost condition) on my VW Touran '04. Happened while going down a valley 10°, i had like 100km/h and i pressed the acceleration, a little bit over 2000rpm and i felt like cutted the turbo. 🤔🤔

I’m being told it’s the turbo boost sensor and that the boost pressure regulation has exceeded its limit doesn’t that mean the turbo is bad?

@BlatantBurnerAccount Ай бұрын

no, will be the wastegate mate. The turbos the thing making the boost so its fine, its the control of the boost thats the problem. Broken turbos usually underboost and noises mate.

Stuck swirl flaps in the manifold can also make the boost pressure go up. Happend to me once.

On my 2004 Opel Astra 1.7cdti. Driving and accelerating on the highway demanding max boost and engine load. I had a broken vacuum line going to solenoid for these intake manifold flaps. They remained shut so they were blocking the flow and so the boost went up too much. It had no sensor on the flaps or actuator for the flaps to inform the ecu. The boost values never went out of range in the other driving conditions.
