2019 2ss procharged nightmarish codes
D1x procharger
Stage 2 intercooler Race blowoff valves Lt4 fuel injectors & high pressure fuel pump Jms pump voltage booster Tcm & Ecm unlocked by hptuners. Hey guys I need some help, I own a 2019 Camaro 2ss with the current mods above. After the installation I started having different codes for like U0140-00 (lost communication with control module) C0800-03 (control module power circuit low voltage) (P0507 idle control system rpm higher than expected) Those codes cleared after a few trips back to the tuner. Now I'm having a different sets of problems after upgrading to the LT4 fuel system with the jms booster. Now I'm getting voltage issues, I was told this can be because my alternator is going bad so I bought a new one and had it installed and that seems to clear out the other codes I was having. But the car is still going to Limp mode with these new codes that showed up from nowhere P00ca-00 (fuel pressure regulator high control circuit high voltage) P129c-00 (fuel pump driver control module system voltage high voltage)... also after the Procharger install The rpm would spike up and the car would jerk me forward aggressively when coming to a complete stop. I tried to upload videos but it wouldn't let me. Any help would be greatly appreciated, I've thrown so much money into this car I just want it to drive properly procharged camaro ss(2) https://youtu.be/z6V14I686Ww procharged camaro ss(1) https://youtu.be/_PR1YOWfzFE Last edited by Koulmc; 05-22-2021 at 12:36 PM. |

Spent a few years as a truck driver and if the voltage regulator in the alternator went we would start getting all kinds of codes as the truck would start putting out over 15.5 volts all over the place.
Danger with this is that this high voltage can also damage these systems and the computers. I know this is not direct Camaro related experience but experience the same. do you have the ability to swap any of these out to test for this?

Yes I replaced the alternator and the other I mentioned went away, but I'm still dealing with fuel pump voltage issues.

Did you install everything at once or at different stages? I would probably check all the grounds in the engine bay (there is 1 tricky one on the front of the block on the drivers side if i remember correctly, and installing the pro charger maybe this was left off?) also check all the wiring, doesn't really seem like a huge issue probably something just overlooked or not connected properly.

I installed the Procharger kit at first, then a week later installed the lt4 injectors with hpfp and jms voltage booster pump. Yesterday I replaced the alternator. When I bring it back in Monday I will make them check the grounds. Thanks for all the replies

What voltage did you set the JMS up to? Need to stay under 17.4 IMO.

@king lt1 would that cause the car to jerk and try to take off when coming to a stop?
