2002 dodge
edge juice with attitude monitor.

many codes.
limp mode

edge indicated that.
fuel pressure was 14 psi
turbo pressure normal when it tried to run...
trans temp. 124.
exhaust temp. 290 at idle and went up in a normal fashion when it tried to run.

p pcu

p 1693 fault in buss or pcm/ecm interface
p done
p ecu
p 0217 coolent temp high... radiator hose and heater did not indicat it was over heating. temp guage moving up and down the scale.

p 0562 batt voltage low
p 0237 turbo boost low
p 0112 air intake temp low
p 1488 5 volt supply low
p 0342,,, crank shaft possition sensor low circuit
the 0342 I found on the internet

p 0606 internal ecm processor

p 1295,, could not find this one.

P done.
the odometer went back to it's reading.


when I was checking the codes the temp gauge would go up and down. different readings all the time.

the battery guage was low and came back up to normal for not running and back down.. I am assumeing that is the grid heater turning on and off.

this is not drivable at this time. I had my baby boy with me. I was only 3 miles from home.
it would run a little bit.
at times the power was so low I was on the shoulder at 5 mph and stopping. I tried the juice chip at different settings.
the temp guage would peg, then read 190, then cold, then peg..

the voltage guage pretty much stayed around 14..

I tried resetting the codes with my code key reader... (a real peice of crap). It did not read any codes and would not reset the codes that I listed.

the upper radiator hose was really warm, but not supper hot. the thermostat housing was hotter then the hose by quite a bit.

thermostat was a new dodge dealer Item about a year ago.
the water pump was new 2 years ago.

as I said above the heat from the heater did not indicate to me that the truck was really 240 on the temp. turning on the heater made no difference. that is when I noticed the temp guage going up an down in a random fashion.

It ran like you had or were turning the key off and on. I only got one or two bursts of power, keeping the gas peddle around half way down.
I tried pumping the gas peddle. none of this made much difference.

it did not sound like a miss or anything like that.. just on or off, or no power.

I was on the shoulder, at 5 mph or less and doing every thing that I could think of to get me and my son that 3 miles home....

yeah... forgot the cell phone..

thanks in advance for any help you may be able to give me.

the batteries are of un known age, the truck cranks just fine. I have had the truck for about 4 years. the previous owner said he replaced the batteries.

I will have to go look and see if the tags are still on them from when they were installed.

thanks again for taking the time to read all of that.
I hope I provided the information you may need to help me.

I can give you my phone number in a pm if you think you can help me

 

I replace the lift pump with a fass 100 or 150 two years ago. I change the filters each fall. I have not done that yet.

 

batteries are both from november 2008
they are the first interstate brand gold series.

 

First thing to try is disconnect the Edge so you can verify that is not the problem

 

I found a power tap in the fuse box.. then there is a spot on the drivers side fender where it connects.
the monitor is my only fuel pressure reading.. should I just pull the wire going into the box on the drivers side?

 

also, while the problem was going on, trying to get home. I tried all the settings on the edge chip, monitor. it made no difference.

is there a way to reset the codes with out a code reader. the one that I have sucks and would not reset the codes, even though it said it did.

I have a buddy bringing a better code reader over in the morning....

right now the only transportation I have is my rock crawler toyota. really not that fun of a daily driver..

thanks again for your help.

 

Sounds more a electrical issue. Id start with the battery connections and grounds. Check battery cables and at the alternator. If still have the problem, remove the edge till the problem is resolved. While checking the battery cables etc, put a battery charger on the batteries.

 

I'm with Lary.
Totally disconnect the Edge 'box' form the vehicle.
(no need to actually remove, just 'normal-up' all connections)

My Edge Comp took a dirt nap and acted like a toasted VP.

 

A short to ground on the 5 volt power supply to sensors such as: MAP, TPS, A/C PRESSURE TRANSDUCER oil pressure sensor. The 5 volts may be shorted externally as in wiring or you may have a shorted 5 volt supply within the sensor itself. Unplugging each sensor one at a time while monitoring the 5v signal is the easiest way to check for a shorted sensor. When using this method of unplugging each sensor on the 5 volt line, be sure to turn the ignition key off and back on when rechecking the 5 volt supply output. This holds true for the primary 5 volt supply and the secondary five volt supply.
Check also the wires near the a/c compressor transducer for chafing and shorting.

P1295-ACCELERATOR POSITION SENSOR (APPS) SUPPLY VOLTAGE
TOO LOW

I will check those wires.

thanks.

 

checked wires, reset connectors.

no matter if edge chip is connected or not.

cleared computer with scanner.

tried with chip and with out chip..

as soon or shortly after I touch the gas peddle I get.
p0606 pcm processor fault
p0237 turbo low input voltage
p0122 throttle peddle low input
p0117 engine coolent low in put
p0112 IAT sensor 1 low input..


and while I had the air box off I can move the turbo shaft up and down.. about 1/16th of an inch.

please help me.
I am in the middle of a home remodel that we did not get a home loan for because I had the front wall off the house when they showed up for the loan inspection...

right now I can not afford a 1400.00 pcm and a 1200.00 turbo.. and I need this truck to haul my remodeling stuff..

 

missouriman, all those codes could be caused by low voltage to the sensors. The ECM is responsible for generating 5 volt power to the sensors. If that voltage is low the codes will be set.

I will guess that the problem may be a wire in the harness that is grounding out and bringing down that voltage. It could also be that the ECM is not getting a full 12 volts from the battery due to a poor connection from the PDC or the relay supplying power to the ECM.

If I were troubleshooting your truck I would first verify the sensors are receiving 5 volts by disconnecting one and measuring the voltage. You will need the shop manual to identify the connection.

Another possibility is poor grounds. It is always a good idea the clean battery terminals and ground connections. Most electrical problems in vehicles are caused by poor connections. Good luck in finding the problem.

 

ok,, found the PCM I think.. up on the fire wall by the air intake.

where is the ECM?

 

ECM is on the side of the block, drivers side I believe.

 

still not seeing it from the top or the bottom.
