Coil, or CPS on the back of the block at the bell housing on the passenger side.

 

I was wondering about that when I typed my earlier response and I think the answer is it can. Temperature sensors are just resistors that change with temperature so they don't care about polarity. The hall effect used on the cam and crank position sensors should not care either. MAP sensors are piezo electric crystal that changes resistance so it might not be polarity sensitive either. Maybe your transmission solenoid issues are caused by reversed polarity. I'd retrace all the wiring according to the RAM wiring diagrams.

 

So what is the distributor called in the FSM?
yes, I know dumb question, but I cant find its pin out.
Will no or reverse power to CPS kill spark?

Edit: No power to CPS does kill spark. Didn't bother testing with the distributor. Cause I'm sure the answer is the same.

I'll keep messing with this.

 

Cam and crank sensors are hall effect switches. I suspect that they are polarity dependent. (I.E. if it's wrong, they don't work.....) You may need to switch wires on individual connectors if things aren't right.....

The sensor in the distributor is the cam position sensor. It's only job is to clue the PCM in as to which injector to fire, it has nothing to do with ignition at all. Crank sensor determines spark. It's behind the passenger side head, and reads off the flywheel/flexplate.

 

Got it, that's the way I'll go next.
Thank you.

 

I checked the cam and crank sensor polarity and it was correct, so I switched the TPS wires and the cold start idle is now at about 800, I'm sure that will come down more after it's warmed up. Don't have time to let it run for that long right now, but I'd say the high idle is fixed. Damn you all know your stuff around here. Special thanks to DerTruck, you nailed it in the first reply, it just took me 2 days to figure out why and how.

Now about the Trany codes, I have P0711 and P1763, both related to the Governor pressure sensor. As I understand it. Is that correct?
After I pulled the drivetrain from the doner Durango, I went through the trany some and put in a kit that allows the fluid to circulate in park, along with several other things and a new HD sensor, solenoid kit. The trany is a '03 and I replaced the sensors with the same year. I did switch out the NSS/backup plug for the older version and the rooster comb to work with the older plug on the harness. I'm probably messing up the terminology since it was several months ago.

Anywho, I have come across some mentions of guys switching out their older Ram tranys for newer ones and they have the same codes. And the only sensor that's different is the Gov pressure sensor. This is why I believe the above codes are from me having the newer sensor hooked to an older computer.
I have a new '98 lockup/OD solenoid and it's wiring harness and a new Gov pressure sensor that I believe will fix my codes. Does this make sense?
Of Course it can also be because the wiring is reversed as with the idle issue. Does the 8 way connector share the same 5V and ground as the engine sensors? It's been months since I put it together and I can't remember.

My initial thought was the Gov sensor since the temp sensor is incorporated into it also.
I'm gonna stop now since I'm rambling. Any Thoughts are greatly appreciated.


Thanks again!!

 

If your PCM is from a 98, then yeah, you need the electronics in the trans for a 98 as well. I think the connector inside the trans for the lockup, and O/D solenoids is different on the newer transmissions as well. So far as I know, the pinout on the trans 8 pin connector didn't change throughout the entire production run. (so, 96 and up should be the same.)

 

So, changed out the gov. pressure sensor and the corresponding torque convertor sensors with the correct harness for the older 46re and I still have the same 2 codes. P0713 and P1763.
I have also swapped out the 8 way connector, the old one was looking pretty bad. That was before changing the new gov pressure sensor for the old one.
Now I'm at a loss as to where to go next. Any thoughts?
Guess, I'll check the wires for those the gov pressure sensor.

Thanks

Edit: I have checked continuity between the 8 way plug pin 4, gov press signal and pin 29 on pcm plug and pin 8, trans temp sensor signal on the 8 way connector and pin 1 on pcm. Continuity is good. And I have 5v supply to pin 2.
Another question: Where is pin 3 on the 8 way connector grounded to. Yes, I should know that, but it's been a while since I made the connections and I can't remember and want to double check my work.
I have 12.4 volts with - lead to pin 3 (8 way connector ground) and 7 V with KOEO. Does this mean anything?

 

With the engine not running, you shouldn't see any voltage on the 12 volt supply wire. Trans relay should disengage until the PCM sees the motor turning. Wonder if you have a short somewhere......

 

That was a way to check ground, as I thought it should be checked, quiet possibly the wrong way to check ground.
I put the plus lead to batt pos and checked ground on the connector with the neg wire from myltimeter.
This is where I got 12v with ignition off and 7v with koeo.
This 5v difference is making me realize that there is a 5v short in the supply line. Does that make sense?
