Hello everyone,
I have a 2022 Ford edge titanium equipped with a 2.0 Ecoboost 2.0 Turbo DOHC with 31,000 Miles and I have a check engine light (quality ford product..) Scanned the computer and I got the code P2AB8 Wastegate Position Sensor 'A' Circuit Low. Car runs like it just rolled off the showroom floor. Any ideas? Help!
So here's an update for everyone: I finally got my car back from the mechanic yesterday, after two weeks waiting for parts to come in. Here's what it said on the RO which my mechanic failed to explain to me: "Verified Concern. Retrieved DTC P2AB8. Followed PPT HN. HN1 Yes, HN30 No, HN31 yes, HN32 yes, HN33 yes, HN34 yes, HN35 yes, HN36 no. Installed new wastegate motor. Removed and installed new wastegate motor with new hard wear. Cleared DTCs and Reset KAM. Post road test no DTCs Present and vehicle boosting properly. No further concerns at this time."
I don't fully understand what this means. Can someone explain?
Check the wastegate actuator for any obvious problems.

@chucktobias It just so happened that I had an appointment tomorrow at a new to me experienced mechanic to resolve an unrelated issue so this will be added to the list. Will update when able to.
@chucktobias I will also show that document to the mechanic tomorrow.
What is a wastegate and what does it do? and a wastegate sensor? Why would it throw a CEL if my mechanic says it's safe to drive around town until the part comes in from ford on Monday
The wastegate is essentially a vent. If you revv the engine to the point where the turbocharger kicks in (forcing more air into the engine than possible with ambient air pressure alone is what the turbocharger does), and then you suddenly let off the gas (you aren't demanding power from the engine anymore), the wastegate will vent under normal conditions, rather than the now-pressurized air forcibly going backwards, through the turbocharger again and possibly damaging it. If you're light on the gas, it's not a big deal, but if you're always flooring it, it could cause issues.
You'll know when the turbocharger kicks in. There will be a sudden increase in torque (the force that pulls you back into the seat). In my wife's 2017 Mustang with an EcoBoost engine, that is around 2500 RPMs. The turbocharger kicking in will vary based on engine size and displacement.
Can someone explain?
What is there to explain? You had a failed wastegate motor and it was replaced, and the associated codes cleared.
@chucktobias That's all I needed, thanks for explaining!
So I went to the mechanic today. Mechanic hooks up his fancy scan tool (like what scotty has) and says that there is something called the Wastegate sensor. That Is what tested bad. New OEM part is on order from Ford now.
@fishingandcarsenthusiast123 That would do it. On old turbocharged cars like mine the wastegate is completely mechanical but I could see sensors being involved in a late model setup.

@fishingandcarsenthusiast123 The wastegate is used to control boost pressure. An internet search will reveal all the gory details.
