Po134 and po154 and po300. The sensors are showing voltage readings when I look at the live data. I cleared the codes. I need to go drive it to confirm the p.o.300 was old code. Keep in mind it has the 411pcm in it. Never through any codes before I tore into the engine and swapped computer.
What year is your truck? What style o2 sensors are they? Triangular or flat plug?
