i need your help, I have , 4 wire, 2x whites for elements and black/gray for signal. I been getting 0141 and 0138 which points to the downstream o2, and i replaced it and still getting hi volts b1s2. i checked the voltage on the truck side, and im getting 13v for the elements and 4v for the signal. my upstream sensor is working fine and no other CEL codes have returned its always 0138 and/or 0141.
truck has brand new fuel pump and remaned. bosch injectors
i checked the elements on the old and new o2 sensor im getting good resistance 5-7ohms
im might pull the old heat gun and see if the old and new o2 sensor can produce it own voltage
