P2200 NOx Sensor Circuit Bank 1 on 2012 ford powerstroke
I have the MAXISYS MS906TS and my issue is P2200 NOx Sensor Circuit Bank 1 on 2012 ford powerstroke, during live data test the range for NOX sensor is -1 to 1 however the actual is 219 and in red print. How do you reset that number? I replaced the NOX sensor but the number still reads 219 in red print.
Weird numbers in live data are usually due to either a scan tool that doesn't talk the language as good as it thought or perhaps an open circuit in the wiring.I'd first try a different scan tool but since the fault was there I'd suspect a bad connection in the wiring.
Getting involved in discussions because I have a lot to learn still.
