Fiesta ecoboost overboost error

Recommended Posts

Hi guys 

My son has a ford fiesta 1.0 ecoboost and it has an issue with the p0234-22  it suggests to change the turbo solenoid does anyone know if this is an individual part that can be replaced as I am aware there are few parts which can be changed on the turbo otherwise its a complete swap put of the turbo..Will it also be worth checking the diaphragm and wastegate as I have read these appear to stick or deteriorate.

What would your best  guess be on repair for this type of error.

The car is a 2016 model, I am also wondering if the previous owner may have tried to override something to try to improve the turbo in someway..

It's his first car so trying to find a solution that hopefully is affordable.

The turbo solenoid is a separate part from the turbo itself. If necessary it can easily be replaced with a new or used item.

The solenoid itself can be checked for correct operation. There is a lot of info online, including on YouTube, or a garage should be able to quickly check for you.

As you mention there are other possibilities but provided it's not a problem with the turbo itself it should be fairly easy and relatively inexpensive to sort out.

Looks like this. Check that the tubes attached to it aren't split for an initial quick check.
