Code P054A

Good morning,

I attached the possibilities for this code.

In most cases, this code is set from dirty oil. Dirt and debris gets into the VVT and it becomes stuck.

The engine oil system has to be pressure cleaned internally of all dirt and debris. Adding a cleaner and changing the oil does not do it. It needs a machine that will attach to the oil filter and the drain plug and force a solution through that removes all dirt and debris from the passages.

I would do that first before looking to change any parts.

That oil service runs about $85.00 to $100.00.

299 code.

P0299
Descriptor
Turbocharger/Supercharger A Underboost Condition
Probable Causes
Air Leak Between Turbocharger and Throttle
Turbocharger Wastegate Regulating Solenoid Valve Stuck
Turbocharger Wastegate Regulating Valve Solenoid Damaged
Wastegate Control Hose Open or Plugged
Wastegate Stuck Open

Pardon if I put my two cents in, for the P0299 Ford has a service bulletin that has us checking the turbo wastegate operation but I have been doing bypass solenoids like crazy! The diaphragm gets torn. It is mounted under the charge air cooler and is super easy to replace. I've attached an actual picture of one that I have replaced.

Not really. Can you please shoot a quick video with your phone so we can see what's going on with the replacement, that would be great. You can upload it here with your response.
