Fuel pump control module failure

[tayamaha]

My 2016 3.8 Genesis sedan car started with “check PSB” warnings which now led to a check engine light that when scanned tells me “U0109 lost communication with fuel pump control module”. Car still runs but runs crappy.

Where can I buy a quality pump module online?
Does it have to be programmed or does the car’s comouter system know to do it once I plug a new one in? It looks like an easy swap but if it needs programmed I don’t want to be stuck. Any help would be appreciated to avoid high dealer costs.

@tayamaha did you find a solution?

Hyundai cars have two fuel pumps. Low-pressure fuel pump (LPFP) and high-pressure fuel pump (HPFP). They can fail, preventing your car from looking in or causing low-pressure error messages to appear. If you have problems when the car runs unevenly and the engine speed will not exceed 2000, the problem may be in the fuel pumps. I plan to change the pumps in my car when I'm completely done with the installation. It may seem like an expensive procedure, but it's worth it.

same code and others was fuel pump mod. 650.00 at dealer 4 days in and car seems fixed

I've been through this, around 650$ for the module (located in the trunk) and labor cost.
Mine failed after the dealer tried to clean the throttle valve and after that it get corrupted. I drove some time with that corrupted valve and the pumb communication start to get lost

What were the symptoms car was experiencing before replacement?

My 3.8 2015 Hyundai Genesis Sedan has some experience with the PSA alarm. The auto was purchased used in 2017 with 19,000 miles and started this sounding the alarm on occasion shortly after purchase. It would only occur on occasion. The auto still ran OK when the PSA warning occurred. The local Hyundai dealer was unable to duplicate the problem. I purchased a used fuel control module off Ebay for $35 but never did get it installed. About 2 years ago I decided to install it but had misplaced the module. So, I purchased another one, this time it was $78 on Ebay. It came with a tag stating it would need to be adjusted after installation. Well, I installed it and without adjustment the auto ran great. It has never been touched since installation. Auto runs great and gets good gas mileage. The PSA has never come on since the changeout.

We also have a 2015 Hyundai Genesis 5.0 Sedan with 53,000 that has never had the PSA warming occur. I have located the misplaced fuel control module in event it's needed for either auto.

There are no adjustment points that I could see on the fuel control module. It there is an adjustment it may be somewhere else using test equipment. It's a little difficult to access but easy to change out.

To be safe purchase a new fuel control module and have the dealer install. Or install it yourself and check it out. If a problem you can always reinstall the old one.

There is only an electrical connection to the fuel control module. No fuel hookup.

I got the same message - “check PSB” - the other day on my 2017 G80. I also scanned vehicle and got U0109. I called dealership and asked about updated replacement for the fuel pump control module and they wouldn’t provide a part number “per policy” unless vehicle is over 10 years old. haha. I currently have part number 33040-B1000 and I asked if I could replace with a 33040-D2000. They took my vin number and hinted that “the last five numbers that started in D would be the correct replacement part”. Good thing I understand speaking in part code. I purchased the module and will be installing next week. I reading different things about having the fuel pump control module programmed. Does anyone know the answer? And does that have to be done at the dealership?

my dealership did mine but no program was necessary to the best of my knowledge. In hindsight wish I did it myself not difficult

I have a 2015 Hyundai Genesis 3.8 Sedan and this issue stressed me for a while since my car had just gotten out of warranty. My car suddenly lost power on the high way and wouldn't accelarate, it would then proceed not to start for the next 5-10 mins. The dealership diagnosed as a faulty fuel pump, told me it would cost $1500 to fix it, I bought the Fuel pump on ebay and changed the fuel it myself but the issue persisted. I was disappointed and tarted thinking maybe I did something wrong or the fuel pump I purchased was bad but I didn't give up.

I then purchased a Blue Driver bluetooth scanner and scanned it myself and got code U0109. I bought the part and replaced it myself, it's in the trunk, on the left side, but it didn't work right away, my car was still not starting, I was crushed but didn't give up. it took a while to pick up after I swapped it, the car was still not starting, I disconnected the battery then disconected the fuel pump connector from the fuel pump under the back seats then reconnected it and reconnected the battery then attempted to start it again and it started on the first try, I was the happiest person in the world since I had not seen my 2015 Hyundai Genesis start in about 2 months. In conclusion I did not need to reprogram it. I really think disconnecing and reconnecting the battery is what did it.
I also bought the part from amazon, OEM Genesis part but slightly different number then the one I removed from my car. See the link below, I really hope this helps someone. The job was easy with a few tools, save yourself or someone else some money. I would highly recommend the Blue Driver Scanner, very handy but obviously there are many other scanners out there. I was not paid for this either true story.

Did the 33040-B2000 work same as 33040-B1000? I have a 2017 Genesis G80 3.8L 2WD
