Good one, Twiggy. If you could get the code, post it as well so it becomes very useful!!
I don’t know what code it threw because I acquired this sensor after the fact when my SIL had it changed. She doesn’t know the code and she doesn’t have paperwork stating what the code was. But very likely the code was for A/F Heater fault? Just a guess.
I work in a Failure Analysis Lab where I work primarily on automotive hall effect sensors to find out why they fail. Every returned assembly gets x-rayed giving me free access to this machine.
