Recently got a p0306 code along with a pending p0405... anyway to tell which one is causing which problem? If the p0405 caused my misfire and I replace the cop, will I just destroy another cop cause the p0405 was my issue or if I replace the egr sensor or valve will that grenade itself again because of the misfire? Just trying to figure out which side to start from.... or are they completely unrelated and came up at the same time?
Yea, as said misfire first. 306 connector/harness is in the same proximity as the 405. Anything happen in that area ? I'd check the connectors and harness visually first. Did your PowerBall get away from yuh while polishing the engine compartment...Mr. Detail ? Other than that those two DTC's have nothing in common.
405 isn't that common. 12 Volt side vs 5 Volt. Yea A = 12V, B = 5V. 405 has nothing to do with the misfire or vice versa. There's also no drivability concerns w/405, so just focus on the miss (306).
PO405/ "A" Circuit = 1676/ C2 The solid grey wire (signal). 12V (VREF) solid red wire.
Could be a wire shear, broken inside the insulation at the bend. Most likley the bend at the connector. Also look for melted harness damage and EGR/DPFE hoses.
I finally got around to trying out the Forscan app. Pretty rad, I must say. It will let you test functions of the GEM, PCM, etc. Didn't get too far into it because I feel like crap... but I did snap a couple pics. Here's the info it got from the PCM on system components, and also the adapter that I use for both Forscan and Torque Pro.

that is pretty cool. I may have to pull that app too.
Kewl little ELM. I have a little different one, but they really are fairly much the same. Some have more capabilities though. Below is mine, but mine's green. Keeps it easy to find. I need that.
White...could you try the readings for the EGR and see if it does any flow readings or what it does read for that system? I'd be interested if it goes that deep. You did say it shows the GEM readings?
Oh I don't know lol. Suppose I can look up the capabilities. What are you looking to get from it that may help you in any way? I guess, Iduno lol.
What is it, Forscan, -got it. Haven't heard of that one yet.
Yes, it is a Ford/Lincoln/Mercury specific app. Member mbb said it will do PATS programming, which is what my main liking was. Have not got that far into it yet though (not that I need it right now, but I like new tools).

I saw EGR functions in the mapping/graphing options, I'll check it out. As far as GEM functions, it will let you test relays, functions, etc. that the GEM is responsible for. I saw that you can also check dash lights for the 4X4, etc. Didn't really get into that either. I was monkeying around with it yesterday morning before work, and I did see an option to check each injector though.... and I really don't know what it's checking for? Resistance maybe? But all of them came back saying "no fault". See pic....

I need to get one of these for my Dad, or set his up to run through his Chromebook now that they can run Android apps now too.
