Both A/F sensor heaters bad??

Tim007 · 2021-08-05T19:43:04+0000

Popping p1135 and p1155 codes. Verified wiring ( by professional). Ran extra grounds. Replaced both sensors with Lexus supplied Denso units( from VIN). Tried 3 different ECUs. "Deep scan" reveals resistance just " a bit too high". Fighting this for a few months now. Can't get inspected or registered this way. Thoughts??
