2013 Dodge Caravan Purge Valve Circuit Code P0443 (New purge valve) Part 2

[@ScannerDanner]

My questions at the end, about why running a ground wire back to the PCM: 1. For input circuits, this helps clean up the signals, I understand that. But this is an output where this type of accuracy isn't necessary. 2. It is an un-switched constant ground on the computer board, but I've never attempted to test one of these circuits with the key off! 3. As many stated in part one, there may be despiking diodes involved for this design. 4. I've seen power side switched outputs that are grounded externally, so what it the difference? If we need diode suppression as the reason, how are these designs done? 5. I understand that it could be a monitored circuit, for current flow. Thanks everyone!! Final thoughts, tread carefully with Flagship1

[@michaelsparmann3368]

This is most likely for 2 reasons: - Flyback protection diodes as you already mentioned (because this is a highly inductive load) - Reduced electromagnetic emissions from the harness, and especially from these specific wires to others running in parallel, by getting ripple current in both directions to cancel out. If this wasn't done, you could see the purge solenoid drive PWM on a current clamp put around the whole harness, that would be a bad thing (large loop area) So this is something that seems reasonable on a PWMed inductive load.

[@galaxian5387]

FWIW I used FS1 for a Chrysler PCM replacement due to a shorted injector driver and had no issues. I think it took a little longer than expected but it was for a 2004 in 2020 - it looked new compared to my NW PA rusty pile thanks to Chrysler for mounting it in the front fender well. Aside from that no other issues and it was plug and play.

[@themechanic2.060]

We used them 5 times. First one was no problem. The subsequent 4 were a nightmare. New codes showing up and other drivability concerns to say the least. It took them forever to correct the problem (sending us a replacement) and on 2 of those four occasions, we had to go and directly pick them up from them. They are about an hour round trip from we are on Long Island, NY. A real big pain in the ass for a busy shop like us when they tout about their shipping. No bueno. Needless to say we don’t use them anymore. We found a great company in Florida for all our re man computers. If we can’t get OEM and we can’t program them we call them. Take it for what you will. Great channel.

I was going to say that the stalling or rough running pertaining to his one initial complaint came to me as you were ending this video, that when you closed the purge valve and it stalled that the ground side of the wire in the computer may have making random or spontaneous connections before having it diagnosed. But you came to a near conclusion understanding as to the rough or stalling issues. Excellent work.

I wonder if the glitches on APP2 are from internal diagnostic workings inside the PCM, ignored on their diagnostics because retrograde glitches are expected as part of a dynamic diagnostic phase.

[@ScannerDanner]

They don't exist externally on the circuit, so I think it's a Snap-On scanner issue.

[@joranlinders]

Opel works that way, pulling app2 down. If app1 goes down together the pcm knows they are shorted.

[@Dr._Diag]

@@ScannerDanner they do exist on all scan tools, and is part of a checksum monitor.

[@JrSpitty]

Yeah the Chrysler thing with APP2 is true. I work at a RAM dealer the first time I saw it when they were training us in classes it through me off. But basically its a self test the computer does to verify it has control of the circuit and since its a redundant system it only cares to test one side of it. Same thing with the throttle body, just don't stick your finger in there with the power connected... It will snap your finger off. LOL

Having the ground going back to the computer would ensure a consistent ground, i.e. a bunch on things grounded to point A, and a bunch of other things grounded to point B can lead to a slightly different ground potential between the two and this can drive computers crazy.

A few months ago i had a 06 grand caravan that would stall under acceleration. I determined the crank and cam sensor where loosing grounds. Long story short shared grounds, when egr when it opened it would pull down the ground circuit for cam and crank. I simply relocated sensor ground for egr to block and all is well. NO codes. I never really understood how egr pulled sensor grounds by opening. And yes tried a new egr with same results. I have been wanting to ask you what you thought about this for awhile. I appreciate the feedback and thoughts there is not many people to ask tough questions to especially around here and with out your training I never would have fixed the car!

[@athhud]

If you don’t have to return the core, crack that sucker open and see where that ground trace goes. If it leads into a muddled mess of integrated circuits, let it remain a mystery. If not, you might see that it runs right into a ground pin going out with just a bit of filtering along the way. Which still won’t explain much as to why, but I always have to tear it apart... :D

The only electrical component inside was a single little zener diode or something like that (I don’t remember exactly what it was). The stuff that the sand was soaked in had a very distinct odor that I was not familiar with, I assume some kind of heat dissipating material. I couldn’t believe that a $30 part the size of my hand would be 80% sand 19% casing, and 1% functional parts. I don’t know if they are all built like that, but I know I went through about a dozen of them (under warranty) before finally changing brands, so I wasn’t replacing them once a month.

You can also buy used pcm at the junk yard for cheap and to get it faster then you can use the autel to reprogram the useded one once it's installed into the car all you need to reprogram is Vin and milage and done.

As far as the ground, i think noise plus in case of solenoid failure and ecm detects it, ecm can take ground away, control wire get shorted to power valve be open all the time, than it can take ground away? Just a thought.

[@ScannerDanner]

I've never seen this type of circuit use a switched ground. If we are power side switching it, there is no need to also switch the ground. GDI injectors do this, but not these circuits. Not that I've ever seen

[@3TsMOBILEAUTOMOTIVEREPAIR]

I’ve have hit or miss with flagship. Last pcm I got from them they programmed the wrong vin in it. Still waiting on a refund. Others were fine. My main issue is there return process is too long takes over a week to get a call back and come up with a plan for there mishap. So had to go so e where to get pcm faster. So now I’m getting an MDI and doing my own programming again.

[@cpcoark]

For computer circuits, it is not uncommon to have your hard power supply ground and a floating common. Can also be called signal ground, floating ground, isolated ground. I do not recall the proper term. On our remote terminal units, this was accomplished with 2 diodes in parallel cathode to anode providing a 0.7v isolation. This helps with ground loops and noise. when you get a chance, measure the potential difference between the 2 "grounds" on that car.

[@mikes3424]

Just a heads up there is a throttle learn on dodge. You can bypass there learn by KOEO then stepping on the accelerator slowly to the floor hold it for a second and slowly let off should really be done every time a battery is changed or disconnected. Otherwise u get that code

That is a good tip! Thanks. So that code was there due to the throttle not being learned yet?

i wish they could get the diagrams exact, because the SIG wire and the RTN wire both were labeled PWM. We know the SIG pulses the circuit because when the ground was constant the pulse was still happening. So could the ground be used to check the circuit for any other purge related codes other than purge solenoid circuit code? Like the p0440 GENERAL EVAP SYSTEM FAILURE?

if the ground goes somewhere other than back to the ECM board, it could become elevated above the computers ground level or vice versa and cause the valve to be controlled wrong or think there's an issue and set codes. also there's back EMF pulses and you wouldn't want them running backwards through or across other grounds in a big ground loop. that could whack all sorts of things out.

[@johnmarkferding8943]

I read something about a year ago where the Chrysler Dodge vehicles use the ASD relay and the computer after the vehicle has been shut off to run the purge valve several times. this may take up to an hour after shutdown. this may be the other monitored circuit that was/is looking for that ground and why it was throwing that code in video 1.

[@Dr._Diag]

No purge solenoid actuation with key off after shutdown, but the PCM does monitor the ESIM (emission system integrity monitor) to see if a natural vacuum occurs, which should suck the plastic weight inside the ESIM up, closing the ESIM switch, and the PCM can monitor how long the switch stays closed to determine if, and how large the EVAP leak is.

[@josephwash109]

I'm wondering if the old PCM was actually good and just had a faulty external ground. It seems to explain everything. If the ASD relay uses that same ground, it seems likely that's why it was also setting a code for that. Intermittently, the ground reaches a point where it can't support current flow for everything, and it drops out. This would also explain the stalling, even after the replacement PCM was installed. If the ASD relay turns off, the coils and injectors lose power, and the engine stalls. Regarding the ground side wire to the PCM, it has to be there for the PCM to verify circuit integrity. Since it's a high-side driver, the PCM knows when it powers the high side of the circuit, but how can it verify the purge solenoid got the command? If the PCM applies a bias voltage to the solenoid coil and it can measure it on the ground side, the PCM knows the circuit is intact. No voltage measured indicates an open circuit, which will set a code.

[@ScannerDanner]

No sir, I proved the stall was the canister saturation and if it had a faulty external ground on this system: 1 - the problem would have still be there and 2- multiple circuits (not just one output) would have been affected.

Apparently the car needed to learn the new pcm and after a few drive cycles, the car drove normal as before. The pcm went back to the default mode after a week of driving. I called customer service and I had to fill out a form about my issue and a few days later told me to ship the pcm back. I haven't done it yet because I dont have another car and I don't want to wait another month for it to come back.. Since then the car now has been driving normal.

Why not pull the hose to the canister off at the purge solenoid (so you don’t have to actuate ANYTHING), attach it to a mightyvac fluid evacuator for 15 min (with the fuel filler cap removed so you don’t collapse the tank) to remove raw fuel, and vapors in order to prevent stalling condition. ASD (auto shutdown) circuit is controlled with a low side driver in the PCM, with a fused power supply on the voltage side. I would IMAGINE that the internal ground distribution got screwed up some when you made the ground for the purge solenoid. Now that the ground circuit is constantly grounded….. It’d be nice to see module power, and ground distribution.

I put a Flagship One ECM on 2007 Dodge Charger 3.5 HO V6, due to hearing about how Chrysler 300 and Charger going into limp mode. Didn't have an issue and then, keep in mind too it had gone into limp mode about 3 times before replacing the ECM, then come to find out it went into limp mode again after the ECM replacement. Made a bad call again thinking throttle body was acting up on it, replaced that (I know Parts Changer cannon lol) then it went into limp mode again. Well did all the continuity checks to every sensor related pretty much dealing with this problem and never would guess why. Stupid red tabs on the wire connectors love to break off on Chrysler/Dodge vehicles at least in that MY and come to find out, my wife was helping me and I saw something happened on my Autel scan tool and it was either TPS or APP related and asked her what she did, she had wiggled the connector on the throttle body. That's when I had my AHA moment lol. The red tab being broken and not keeping it locked in place, the little vibration in the engine it jiggled off, so had to temporarily fix it till the owner can buy a new wiring connector for it. So in my book, Flagship One is okay to me. I do have a question for you and was wondering if I could email you my question at some point about an intermittent stalling that happens on my 2014 Chevy Malibu 2.5L LS 4 cylinder after certain Auto Stop events. My email is [e-mail] and awesome videos all the time from you. They help me tremendously. On a side note, I hadn't really watched many of your videos till after replacing that ECM on that Charger. Now I always check grounds, powers, fuses, everything I can. I even was able to diagnose my own car issues except the intermittent Auto Stop stalling on my vehicle better than the 3 weeks I took it to the dealership. So Thank You!! I appreciate you.

Used them alot... Hardest thing with them is customer service. Very frustrating. Once we get the order going they have been ok...

I have one only question to you mr.scanner Danner oh my gosh ...how to be you 🙂🙂🙂

[@detailedautodiagnostics]

As a mobile programmer, me along with most other programmers cringe when we find out we were called into a vehicle with a Flagship module...they have their place and success...but many times there are additional steps and failures that the customer gets faced with 🤷‍♂️

[@ScannerDanner]

Agreed. Tread carefully. Better to call one of you guys!

Flagship one ECM for GM's sucked. I had to return everyone for refund. I had better luck buying used ones and reprogramming with my GM MDI2 and SPS.

[@jimmyphillips2216]

I also had an issue with Flagship 1 working on a Jeep Wrangler. After 3 weeks, no shipping notice and they kept telling me it would ship next day. I demanded refund and secured a PCM through other supplier. Long story short, they jerked me around and I lost weeks and customer started to think I was the issue.

[@richscruggs2858]

i have had bad results more than once, stopped with them

[@diy_automotive]

Same deal here. They didn't have the ecm I needed but said they'd rebuild the one we had. Vehicle issue was it would randomly stall. Got the ecm back and when it would crank the cruise control would pull it WOT. Took 4 weeks to get the ecm back after they said 1 week turn around, contacted them and they said they'd take care of it and send me a return label... 3 weeks went by with excuses and different people because the other person wasn't there etc. Then they said we damaged ecm before originally shipping and all kinds of crazy stuff, said they replaced the connector. After 2 months of being drug around on sending the unit back I decided to pop the cover off (no tamper label and still just as dirty as when we mailed it to them) it only appeared they replaced a few capacitors. Connector was never messed with and no jell removed from any part of the board besides where the 3 or 4 capacitors were.

Just bought a PCM for an 02 Dodge Caravan from them. Supposedly programmed to the VIN and wont even start the car. Old one at least will.

[@ScannerDanner]

Yeah, they truly are hit or miss

I was talking with pinehollow ( Ivan) on a 2014 dodge van with a app code. I told him I figured it out app 2 signal keeps dropping out and he said look again. Sure enough that was not the issue. It ended up having the 5 volt supply shorting to ground (a wire rubbing, it was the hardest find because it only short for a split sec. plus it wouldn't act up for hrs). Its weird it only set app code even though the 5volt supplied throttle position, crank sensor and a couple other things. I would of got burned if it wasn't for ivan .

[@dans_Learning_Curve]

He's s smart guy!

[@ScannerDanner]

For sure. Ivan and I go way back as well! I would say he was a former student 😉 before he leapfrogged me in this field. But thats the way it is supposed to be!

[@billmonroe8826]

Damn, I just priced an ECU for a 2006 jeep and they are asking $850. I wonder why it was so much cheaper for this van?!
