Sounds like its an intermittent problem.  To answer your question, no. The ECM sees an electrical fault (open circuit). Try leaving it unplugged and see if the shutdown light turns on. Is the malfunction indicator light on? Coolant temp will cause it to shutdown as well. There should be 2 sensors at the rear of the water manifold. The one sensor at the very back of the water manifold is the coolant temp sensor. Unplug it and see if the trucks shuts down.

Hope this helps

I unplug the back sensor truck shuts down 

 

I just did about the Samething as you 

I purchased a excavator 

but I got my gladhand kit from anything trucks 

haven't Installed it yet but seem to be everything I need 

bunch of good videos on YouTube

I just need to figure out the trailer wiring now before the gladhands 

when I unplug the oil sensor on top of the filter shouldn't the shut down light come on  or shut the truck off

sorry 2000 rd688 e7 400

my shut down ligh. comes on randomly and shuts down sometimes not all 

but fires right back up

I've changed water level sensor

water is full

oil is full 

I could really use some help 

I haul asphalt for a living and I'm afraid it might shut down not start back up 

thanks 

ok guys my shut down light got where it comes on when I hit breaks hard at a stop or if I have to stop suddenly

I changed the water level sensor still no change .

what can cause this where should I look 

every now and then it shuts down but only when I'm stopping

both tanks are full 

thanks guys

truck is a great truck works everyday 

I have a new truck ordered and don't plan to deal with drivers anymore I've had enough

rear bushing will need replacement soon 

truck has new floats on the front 

new clutch and flywheel 

demolition body with high lift gate 

I've replaced the turbo yrs ago and 1 eup everything else has been basic maintenance done 

I'm asking 40000

cause Bushing will need replacement 

there not walking but I feel a vibration or bump in the rear and a pay attention to the Rear-end

I replaced the vent a while back that could have been the problem

it was leaking before I got hit but I was thinking it was the side cover

I see my bushing are about gone or gone 

I feel a little vibration I'm sure it's coming from the rear 

I was hit in the side front to back about 8 months ago and I could see where the spring had hit the saddle 

it was put on the freak machine and alignment machine

was told in spec but I see the bushing the rear is moving back and forth not alot but it's there 

all tq rods was replaced bout a year ago 

is this a tough job or can be done at home with normal tools

if possible I'd like to replace with greaseable set up 

ok guys looking my truck over I see the grease is coming from the seal that's behind the big nut holding the rear yoke in the rearend

is this something I can do or need to be done by shop 

I know on my race care it helps with the lash specs

but not to sure on this 

yes sir mack rears 

just trying not take them off miss work before I get some to swap out 

2000 rd688s

If the flywheel he used is a aftermarket it may be like one i used and it is made for both engines.It has the missing tooth and the six little slots in the flywheel and which a portion of the slot goes over into the ring gear.I had a ring gear slip about 1/2 inch on my E7.

I'm kot sure but it ran fine for a few weeks after it was installed

they could have damaged the wire installing the new stuff 

they removed the fuel tank and everything on driverside

with the cam sensor out and flywheel sensor in, the engine does not start... I would look at the wires to the flywheel sensor,  follow it as far as you can and gently tug the wire, hope fully it will break somewhere easy to reach and you can solder it back together. also, the plug on the truck side could be dirty, and/or have bad pins in it. it is close to the ground and gets stuff slung onto it from the steer tire, plus whatever the engine leaks out gets on it too...  Lot's of great info in this thread... I'm sure the answer is already posted. let us know.. jojo

I'll check that this week 

it runs with the sensor out unplugged at bell housing 

I hadn't thought of a bad wire or plug 

I did spray the plug with brake kleen to clean it out when I installed the new sensor

Is this engine a E-tech or a E7 older,  The E7 uses the screw in sensor at the front of the flywheel housing, the E-Tech engine uses the sensor that push in from the side and a little bolt to hold it in.  There is a difference in the flywheels.  The E-Tech has one tooth on the flywheel that has been cut off.  The older E7 has 6 holes on the front side to line up with the sensor.  Make sure you got the right flywheel.  Also did the crankshaft have a dowel pin in it, If not it could be installed in the wrong place.  

e tech I believe

it's computer control

it has the sensor in the side of the bell not front

I had a shop replace the clutch and flywheel

Mike is the tach showing RPM? Just wonder if your chasing the wrong thing here Fuel transfer pump comes to mind! just saying!

yes tech and mph works 

speedometer and hr meter does not work it stopped a while back

my old 2000 rd690s

300 e7 Allison auto

was a great truck kinda slow but I'm Pais hourly lol 

also the flywheel was purchased new not resurface

buy not from mack from another parts supplier

mack had a long wait time 

this is my only truck income right now 

no real concern of the flywheel what's just told it could be the issue

so where do I start 

I pulled the bell housing sensor and it would run but I replaced it with new from mack anyway 

then pulled cam sensor no start at all 

and thanks guys I really appreciate your help 

I really need this truck fixed 

ok guys I had my clutch and pressure plate replaced months back a few months after I got a 3/2 code while driving down the rode 

I checked code it's speed sensor

I replaced both in bell housing and tail shade code still there 

now the truck has lost some power cause now I have to down shift more to climb hills that I never had a problem on 

also the truck is hard to start have to keep turning g ot or either spray it for faster start 

even after it's hot it's kinda hard to start but not as bad as first start of the day

I'm thinking ring gear has moved on pressure plate

if I remove the sensor in the bell housing truck will still start but still hard 

if I remove cam sensor on front the motor the tru k will not crank 

any guidance would be great this has been a great truck last 4 years 

but I can't keep dealing with it as it is now

thanks 

clutch from mack 

pressure plate from outside source 

trying to locate a fuel tank close to nc if possible 

tank is about 34 long 24 wide filler neck bout 7 inches from back of tank 

aluminum tank 

thank you for any and all help
