  • Quick help on codes 151, 147

    Alright, finally took the car in to get codes scanned, got 2 back, 151, 147. I searched on 147 and that appears to be the after cat o2 sensor, i will get an O2 sim to fix that one, but 151 is P0151 Heated Oxygen Sensor (HO2S) circuit low voltage Bank 2 Sensor 1. Could that be the sensor itself, wiring, or both? I'll probably just replace that and see if that fixes it because it is OE. any advice? these codes didnt come on until the summer when i put on the pacesetters. Before that i already had a high flow cat and flowmaster am. thunder on and no light. Im assuming they are just reading poor based on the increased flow because of the headers.
