Powertrain Malfunction/ Reduced Power

[snapper9601]

Update on my issue:
(copy/pasted my reply from another thread re: this issue.
Turbo wastegate actuator position sensor faults.

Service Engine Soon light, CEL and Wrench light were all on when I dropped it off this morning.
Service Dept. just called... They confirmed the problem. I told them about the DTC's P2AB7 and P2AB9, they confirmed they saw those as well. The Service Writer says the technician thinks its the Turbocharger Bypass valve causing those DTC's on the wastegate. They want to keep it longer so the tech can troubleshoot more. If it is the TC bypass valve, they likely will need to order parts. The tech wants to continue troubleshooting today, and with the 3 day holiday weekend upon us, they asked if they could keep it until Tuesday. They did ask if it was a big inconvenience. It is very disappointing that this is happening on a 24 day old truck now with only 500 miles on it, but fortunately (I think?) I am in a position right now that I don't need the truck. My wife and I are just traveling a short distance this weekend and will use her car. If I got a loaner, it would just be sitting in the driveway anyway.

More to come....

Just got back from picking up my truck. Svc. Dept. invoice below. They found one code the same as @Jesse-Infotainment found, P2AB9. And they found code P0243 (but no P2AB7). I googled and found OBD-II Trouble Code Technical Description for P0243 is Turbocharger Wastegate Solenoid A Malfunction. This is a generic powertrain/engine diagnostic trouble code. It does seem to fall in line what what was going on.

They replaced the drivers side wastegate actuator and the factory pigtail. No CEL, no SES light, no wrench light, it ran fine for the 4 mile surface street drive home. I'll see how it goes.

2022 XLT, less than 5k miles on it. Had the power train malfunction / reduced power mode check light on. Barley owned the truck for 4 months and already something wrong with it. Called multiple dealerships all telling multiple weeks to upwards of two months to book a service. No loaner cars, such a joke. Now I’m out a lease payment and a car rental payment!

Hi there! Would you send us a private message with your VIN and dealership name and location? I’d like to look into this concern on my end.

2022 F150 XLT with less than 1k miles on and getting the Powertrain Malfunction / Reduced Power with Check Engine Light as well. Ford Pass app says "An electrical fault with the turbocharger waste gate position sensor circuit and its associated wiring." I'm getting error codes P2AB9 on a ODB-II reader. Local Ford Dealer Service shop doesn't have any availability for 2 weeks... ironic that I bought the new truck to avoid inconvenience of mechanical issues.

Very similar problem to those described above. 2022 F150 XLT, 2.7 L. Been in the shop twice already and now in for a third time. First time they replaced the gas pedal assembly and said it was a bad sensor. Second time they replaced the throttle body. Waiting to see what the next guess is and hoping they guess right this time. Will post again when this is resolved and let everyone know what the problem was.

Hello, Marcus! Send us a private message with your VIN and the name and location of your local Ford dealer. I’d be happy to see what I can do to assist. Thanks!

Did the repair solve the problem?

This is what they told me

So far, yes. I've put 2000 miles on it since the repair in September, varied driving conditions. Have not had any problems.

Good to hear.

Mine went in to dealer yesterday for the power train malfunction/reduced power. 6500 miles on it. They told me today that it needs a new starter, alternator and some belts.

Well, I am so grateful for this forum! Quick search sent me here to this thread. Same issue stated by OP @21hybrid F150. Sent it through the car wash yesterday. First, I received the error for the ground fault issue with ProPower. This morning, I received the orange wrench and "Service Engine Soon" warning. I drove straight over to the Ford dealership and they were able to find me an appointment for this Monday instead of the originally proposed three weeks out.

FordPass just alerted me to fact it was a "Powertrain Malfunction/Reduced Power" error. I was without my PowerBoost for 41 days this past year for the dreaded PowerBoost CEL P237C/Exhaust Heat Exchanger Leak. I still love the PowerBoost and don't mind the trips to dealership for warranty work as long as I don't have to play the game OP stated due to lack of replicating the issue. I left a voicemail for the Service Advisor on this new information, but I haven heard back yet. So far, @Ford Motor Company has taken care of me and I hope they continue to do so.

Update: Dropped the truck off at the dealership this morning. The SA just called to let me know the Tech is stumped and unable to determine what issue is the throwing the generic powertrain malfunction error codes. He stated they will be reaching out to Ford to assist with the diagnosis. They will need it for at least another day.

Update: I hope I am not over-sharing. I find it helpful when I read all your posts on these types of issues so I wanted to make sure I followed through all the the way to resolution.

I picked up the truck from the dealership yesterday. They replaced the wiper motor due to the recall which was great. I was told everything is working properly with the ProPower. They find a loose wire which was wet. They tightened that wire and checked all others to make sure they were all tight as well. I still have a concern, but I'm not sure if it's me or the truck. When I press the "Test" button on the ProPower screen, I am told I have ground fault and the affected circuit will be shut-off. I tested all the receptacles in the bed of the truck and they are all working accept the 240. I will have to take my voltmeter to it. Is this typical or do I need to follow-up with the dealership? Thanks for all the assistance. You all are great!

Your Pro Power "Test" button is working as designed.
