O2 sensor...Possible Fix
I have a 1999 GMC Yukon 5.7 4WD and I'm getting a P0157 code which is bank 2 sensor 2 low voltage. I've replaced the sensor and still the same thing. The voltage fluctuates between 0.005 volts to 0.050 volts, sometimes it goes up to 0.080 volts. Now I'm thinking it might be a short somewhere in...- Fatboy554
