I have a 2012 Ford Super Duty, f250, with a 6.2 liter gas engine. It has codes P2251 for negative current control circuit open, b1s1 o2 sensor. I have a Solus Edge and a Verus Pro, both running 15.4, and I can't find pid for B1S1 output voltage, B2S1 and B2S2 both are there and read okay. I couldn't find it in PId list anywhere. I even tried EOBD and not there either. I can read B2S1 as a voltage and it shows good. Am I missing something here? Or is it a glitch? Vin is 1FT7W2B61CEB63175. ADDED LATER, MATCO MAX GO SCANNER ALSO DOESN'T READ B1S1 SENSOR.
