Hey guys. My truck (1997 vortec 350) has had real bad hesitation for the past couple days. Finally today it gave me these codes:
P0102: MAF Circuit Low Input
P0151: O2 Sensor Circuit Low B2S1
Now it seems strange that I would be getting a low signal on both sensors. I checked all the fuses in the cab and under the hood. I searched for the wiring diagrams, but couldn't find one that showed both sensors.
I am curious if anyone knows if these sensors share a common ground, and where it might be?
Or if you have any other suggestions of things to check, I am all ears!
