GMC Sierra 2015 code P0641 with P2228

[Nawafz]

Hi guys 

 

My Obd scanner showing me these 2 codes P0641 and P2228. I tried to delete the codes but as soon as I drive the car on high speeds it shows again ( only the P0641) some time it showed the P2228 with it, My Truck engine has a rough idle and some times it stalls when the codes flashes.

Do you know how to google?

 

first code says low voltage from a circuit

2nd code says maf sensor

 

check your maf sensor, maybe clean it with maf sensor cleaner, check your intake connections and the wiring to the maf, make sure it’s plugged in etc.

What's funny is is that it took him longer to come here and create a profile and all then to just go to google...putz...

I know this is an old post, but I'm having the same issues. 4 DTC's   P0192; P0641: P127C: P2228

Besides the Baro sensor, APP sensor, and fuel rail psi sensor, are there any others on that "A" reference voltage circuit that i need to look into. I'm an electronic tech by trade so I'm familiar with these types of circuits, but i usually have good prints to work off of. GM is quite stingy with their info. 2015 GMC Sierra 1500

Needs fuel rail pressure sensor

Dropping out 5v ref circuit

You’re welcome saved you a ton of time you came to the right spot [emoji23]

Alright guys. I have a 2015 GMC Yukon. I recently pulled the motor and did the sos delete. After reinstalling the motor I have P0641, P06a3, P0697, as well as code for injector 7 low voltage, oil pressure sensor, camshaft sensor, baro sensor basically codes associated with the 5v circuits. Checked all fuses, grounds and wires.
