Hello, i just fixed the killer dowel pin on my 1997 12 valve, as i was putting the harmonic balancer on i did not notice the sensor above was improperly located and it broke :-( is this a Crank postion sensor? and where do i get one? How do i instal it correctly? is there a measurment or gap between the balancer and the sensor? also what does this thing do???? i am new to diesels and electronics. P.S looked for this part all over and it seems like no one talks about it or sells it online, or maybe i just don't know how to type it in the search engine? Thanks for any help!!!!!

 

IIRC that is for the tach signal..... let me do some looking on where you might be able to get it.... if no parts stores have it it might be a dealer item

 

does it look like this?



if so it is $108 from Advance auto parts and is listed as the crank position sensor.



64.99 @ autozone....

 

These are the part numbers;
Engine Speed Sensor
Mopar 4746691
Cummins 3924432

 

Thanks, i guess i know what i am buying from auto zone. Do you know how that is ajusted? or does it just bolt up? i would imagine that you would use a feeler gauge to adjust? P.S Thank you for your fast reply, i am very new to this and am enjoying the site

well, i guess i will never make that mistake again 108.00 bucks, that not cheap, can i drive the truck without that? i didnt even want to try or even start it untill i knew what that sensor did? you said it just controls the tac?

 

on a 12 valve the only thing you need for the engine to run is fuel pressure (mechanical lift pump), power to the starter so it'll spin over, and power to the shutoff solenoid to allow fuel in the pump. IIRC that is all these motors NEED to run.

 

I have that sensor off of a 94 CTD. I thought it went out and replaced it but it turned out to be the tach in the cluster, and they wouldn't let me return it.

I don't know how to PM but I will try to PM my contact info

 

Hey Guys, got the truck back on the road, my friend had a spare engine with the sensor and gave it away for 25 bucks!! now the truck is better than new and i don't have to worry about the KDP!!!! ***** TO THE WALL

 

The clearance is about a playing card thickness, but if it's working OK, leave it alone.
