[HEFF733]

hey guys,
been having a small problem with my truck lately, after i start it up and drive around 2-3 miles it will sometimes jerk, like the engine runs out of fuel?
just for a second. when it does it, it also shoots a puff of blue or black smoke out of the exhaust, no engine lights ever kick on,
another thing i noticed was if if was accelerating hard and rev hard it will cut out the same way at 3000 rpm`s , blow a puff of smoke
any help will be grreat!


so i hooked up my edge evo and ran the diognostics test came back with
six codes...

1) P1280- ICP Curcuit out of range,low

2) P0603- Internal control module, keep alive memory,(kam) error

3) P0344- Camshaft position sensor, circut intermittent

4) P0236- Turbo boost sensor, A circut Range/Performance

5) P0470- Exhaust pressure sensor, malfunction

6) P1111- Intake air temp sensor(IAT) , intermittent high voltage

truck seems to run ok the way it is but i`ve only owned it for about three weeks, so maybe it could run better?


truck is a 97 psd w/ 177k 5-speed,
3"dp, 4" straight xhaust, intake , 10k mod, edge evolution,

cam sensor bad

not particularly the cam sensor... I've replaced mine and scanned it again and got the 603 code also.

Do you have a chip? Have your batteries been d/c recently? 10k mod?

1) P1280- ICP Curcuit out of range,low - this can cause a myriad of problems... jerking, no power, sudden power, etc...

check the ICP sensor for oil.


2) P0603- Internal control module, keep alive memory,(kam) error - battery disconnection or chip/program usually makes this code.

3) P0344- Camshaft position sensor, circut intermittent - Possible cam sensor.


4) P0236- Turbo boost sensor, A circut Range/Performance - I'll look more into this but this can also cause some issues you've stated. This is usually associated with a chip/program, but idk if you have one.


5) P0470- Exhaust pressure sensor, malfunction - this means the sensor has detected an error in opening or closeing the valve, or you have a clogged EBP tube.


6) P1111- Intake air temp sensor(IAT) , intermittent high voltage - meanial code - maybe just a short or it got water on it etc... it plugs into the back of the intake box.

I just noticed this part of your post...

intake , 10k mod, edge evolution

What did you do with the Air Intake Temperature Sensor? Make sure it's zip-tied out of the way and not rubbing the wires or something.

Take the 10k out... it's not helping or really doing anything since you have a program. I'll bet you have oil in the sensor. unplug the sensor, remove the 10k and clean that thing good. Any oil in that connection is a REALL problem.

And the Edge is causing your KAM error.

Nice work Marty, I guess you are a "fart smeller"




Cleaning the EBP is pretty easy, if you need any help let me know, I just did mine a couple days ago.

LOL thanks.

And no need Derrick - I already did a small how-to on it.

i did replace the batts a week ago, i will check the icp sensor for oil and remove the 1ok resistor, i dont think its doin much anyway.
as for the intake air temp sensor i`m not sure , i`ll havto look tomorow, the diy intake was on it when i bought it.
as for as the cps sensor its looks new but its goin in for the cps recall this week... Jason

Sounds like your set. You'll likely end up having the turbo/exhaust pressure codes left after it's all said and done.

I'll get you a picture of the Air Intake Temp sensor.

Here's the DIY intake thread.

Here is a picture of the sensor.
