yes they just parted out the whole car. he didend get the ecm from it. all he got was just the motor. i know it doesn't matter but the two motors look exactly the same. yes the cps i got from auto zone  and not OEM. i will do a relearn on it and see what happens. thank you guys very much. i will keep you posted

So looks like pin 86 is your 5 volt signal coming back from crank sensor and harness. Shout out to member Dean H for supplying this last year. Shouldn't need pcm from other car, both engines have same cps, etb sensors and are compatible.

Sorry for late response....winter weather keeps knocking out my ISP!

 

I will admit that I had been confused as to which vehicle had been "parted out"and now understand it was the Avenger. But how long did the sit? YES it sounds like the now is checking wiring of the Journey. OR did the majority of engine harness swap with the donor motor? MAY be mismatches if that's the case. 

[John/Horace]

Problem with CPS sensor output is that it is “ a series of repetitive electrical voltage impulses generated by a a sensor and rotating shaft”.  So regular ohm meter not good enough, osiliscope or high tec scanner needed to measure. Or keep trying learn procedure on diff CPS sensors until one passes. Resistance/continuity tests on harness could help isolate too.

yes donor car was 2010 avenger. he didn't get the wiring harness so im using the journeys. i tried to do a relearn on the cps and crank sensor and scanner needs motor running to do this procedure. im about to give up. i have done everything you guys said and even the basics . i have a high end scanner. its a ancel ds600. how can i get this piece of junk started?

[Dean H]

I would like to know if the engine cranks over?

 

Be specific as to the speed and how it sounds.

 

Is it possible to post a recording of it cranking?

[5rebel9]

There has got to be some kind of electrical problem. How long did both vehicles sit? Did the Avenger motor run until keys were lost?

Recheck all engine harness connectors AND for ground connection of the engine, a hard or slow crank speed of the starter would be a "clue" to this.

With start button in ACC position you need to check for 5v ref. and then 12v signal at crank sensor and repair as needed. Could be a break in the wiring anywhere back to the ECM.

There are a number of wires that hook up at the starter solenoid main stud, recheck that all are hooked up there.

Sight unseen, it's pretty hard to discern just where your problem is.

Good luck and "Don't give up the ship"!

i want to thank everyone for their advise and when i get home this evening i will do a scan and see if i can figure out how to put a video of it on here. my scanner can do the relearn and also can program pcm etc.. i will try to put a video of what the scanner is telling me but i cant do a relearn on anything until i get it started. i do thank each and everyone of you guys for helping me. yes both motors were running when i did the swap. there is something i am missing and i think it goes back to the cps. motors didn't sit probably a couple months. starting it did have a slow rank but i fixed that. its still throwing the battery sensor code even after i cleared it. i like dodge products espeally the Cummins . i have 3 of them. maybe i will put a cummings motor in this journey and that will fix it

[jdd]

also im not to sure what you want me to do with pin 86 and that chart. if i understood that maybe i could find the problem

[John/Horace]

There are two wires in the crank plug harness that feed the sensor, I assume . If it's three then one is a ground wire, which we will test later. One is the 12 ish volts from battery coming in, the other is the pulsed 5 volt signal going back to the ecm (pin 86 on ecm main connector plug). Both needed to run engine.

 

Unplug cps plug first, then get ignition to run position, make sure one wire on cps plug is getting very close to battery voltage. Report back what voltage is.

 

Turn off ignition, put cps plug back on the sensor again. Can't remove ecm plug to trouble shoot, ignition won't come on with plug removed. Need to do what is called a back probe. Very thin piece of wire or paper clip is used to see what voltage is. Some mechanics poke sharp meter probe through wire insulation, then dab with atv silicone afterwards.

 

To back probe slide paper clip into cps  harness plug beside each wire and get a voltage measurement with ignition on. Do same thing at 88 pin ecm/pcm end for the 5 volt output going to pin #86.

If voltage is dropping through harness or bad cps plug you will see it turn up as a low or no voltage measurement at pin #86. Not hard to lose a 5 volt signal via pinched wire or dirty connection etc. Even bent pin.

For cheap and easy:

 

I would replace the battery sensor.

 

Check and clean all battery cable connections and grounds.

 

Read these threads on doing that.

He said he already replaced the battery sensor. Maybe he didn’t clear codes since. He is not in salt belt I think, but cleaning up grounds is never a bad thing.

 

From wiring diagram it’s a three prong plug on crank sensor. Two out of three wires you can test at the plug, ground and 5 volt reference supply are testable, the ckp return signal, a brown light blue wire to #86 pin can’t really test.

 

Could also test complete ground path from crank sensor ground pin right back to #88 pin on pcm module for continuity and resistance.

[jdd]

i didn't spend much time on it btoday. i tested the three prong cps plug and im getting 5 on both sides and the ground wire is the middle. no salt here in Missouri.unless it snows lol..i bought a new battery sensor and cleared all the codes. i just need to get it running so i can do a relearn on the cam and crank sensorsi added a ground wire from the passenger side all the way to the battery. checked all the grounds and i even cut a piece of aluminum for the grounds on driver side like the pictures showed. still same thing. . so i need to unplug the pcm and check pins 86 ? them plugs are pretty tough to get off there aren't they?
