Bought a 2001 f150 5.4L with an engine swap recently done before I bought it. I have P0141 and P0136, replaced all the O2 sensors with Bosch, but still have the error. Using FORSCAN, on B12 I have 0.63 V, 99.22 STFT%, the heater is on, but my HTRCM12, A (amperage?) shows 0.00. For comparison, my B22 shows 0.47V, 99.22 STFT%, the heater is on, and the HTRCM22, A shows. 0.79. Can you help me to understand what wires to check and what to look for?

Direct fit 02 sensors? Not splice-in, right? Have you gotten under the truck and followed the wires from the sensor and up over the transmission? Did any wires get messed up during the swap? You disconnected and reconnected the sensors to ensure a good connection?

@@ScottiesHobbies i think I have an intermittent open circuit on the heater because I get 12V on both the heater ground and the vpwr wire when I go tugging on it. I think Im gping to have to run a new wire down there.
