Hi Scotty,
I appreciate all the great knowledge and advice you share in your videos. I always look forward to them and enjoy your sense of humor sprinkled throughout.
I recently got a check engine light in my 2014 Ford Escape SE with just over 76k miles on it. I’ve never had any issues with it for the 7 years I’ve owned it which I bought it used with around 13k already on it in 2016. I had the engine light checked at an auto zone and it came back as a P0234 code.
The report auto zone gave me was saying it could be the wastegate solenoid. I go online to do some research and I’m seeing all kinds of issues it could be and honestly I’m having a sinking feeling fixing this is going to make pay dearly for all the years of reliable service this vehicle I got from it.
In recent months I have noticed a bit of a whirring noise when accelerating but no lights, not a thing came of it. I just chalked up to be that the car is starting to get up in age and wear/tear. I don’t seem to be losing power and it seems to be running normal.
I have taken decent care of the vehicle with on time oil and filter changes over the years every 3k miles. I do tend to push it a little when I’m running late for work or an appointment here and there, but not in a fast and furious way but with urgency.
I live in PA and wather has been very cold lately which there are a lot of times I don’t have time to completely warm up the vehicle for more than a couple minutes.
This is my only vehicle and I need it to get to and from work and all. Is this my fault or unknowingly screw myself over and am I in for a rude awakening or is there hope for a decent outcome? I appreciate any advice you can offer on the situation and what can be done or what I should do.
Thank you for your time sir.

Like most codes the P0234 indicates a condition (in this case turbocharger overboost) which can have a number of different causes. You need to troubleshoot those possibilities to find the root of the problem. This needs to be fixed ASAP since overboost can be very damaging to an engine. If you're lucky it could be something simple like the wastegate actuator rod coming loose.
