You have to select "Ford Gas 08 & up" I believeThat PID doesn't show up in my logs using the "Generic 2011+" PIDs on my nGauge. Is there a way to change that? I forget.
Thanks for the confirmation Although I'm disappointed I thought I had a EGT sensor lol.Exhaust gas temperatures are estimated. Exhaust components temperatures flange/ Cats/ O2's are inferred from that estimate. O2 sensors have a duty cycle vs exhaust gas to maintain desired tip temp. They do not have a temperature sensor built into them, just an operating temperature range. Flange probably comes from cylinder head temp and exhaust gas. The Cats are probably some temperature between those two.
There's a lot of math going on behind the scenes. This is the main reason Ford is using a CHT sensor and not a ECT sensor. They can accurately infer a lot of temperatures based on CHT and other estimates, and not have to have 5 different sensors.
