P102B-00 Fuel Pump Motor Phase U-V-W Circuits High
Hi All,
It's your cousin with a 2022 GMC Sierra 1500 Elevation. I wanted to share my recent experience. Drove from Boston to Jacksonville, FL to pickup our new trailer. Heading home we camped in Shenandoah. On the 2nd day check engine light comes on going down the mountain. This truck has had so many electronic issues that I invested in an Elevation OBD scanner and always have it with me. I scan the codes and I get the P102b-00 code. Thanks to you guys on this forum I was able to figure out we were on borrowed time. We found a GMC dealer in Charlottesville, VA who was fantastic and provided us with a loaner car. There were only 4 GM OEM available FPCM in the entire country. The first try was direct from GM, that one never updated the "spec case" and was a no-show. Second attempt was a dealer 2.5hrs away in Norfolk. That overnight delivery never arrived so the dealer sent a driver 5+hrs roundtrip to get the part. Thank sweet baby Jesus there was a part nearby and the repair was covered under the drive train warranty.
Not surprised that GM has a critical part that is known to fail and doesn't have sufficient inventory.
