UGH. well after doing those tests, all signs point to the ecm.

I assume its possible to check these without a scan tool and just use a multimeter on the plug side?

Yeah, it was definitely a moment that made me scratch my head and wonder why I didn't spend an extra half a second and think. I'm just kind of stumped on how to proceed with trouble shooting these codes. hrmm....

Well, this morning after changing my fuel filters i was in the process of jumping power from the battery to the plug for my raptor to bleed the air out of the system when i had a brain fart and grabbed the plug for my deleted fuel heater instead. There was a spark and immediately put the CEL on. So i grabbed my smarty and checked the codes...p0222 idle validation...p0113 IAT sensor voltage high p0118 ECT sensor voltage highp0238 MAP sensor highp01693 companion code I figured i just blew those sensors so i went and picked up a new ect,map,and iat sensor and installed them, cleared the codes with my smarty and lo and behold those codes pop back up again. So in desperation i tried leaving my batteries disconnected for an hour with no luck. Is there a relay or something else that i might have fried? or?
