crank position sensor

NYdiesel_nutz · 02-02-2010, 06:36 AM

hi, new here and to the diesel world. just got an 07 2500 and have had it in the shop 2 times in past 4 weeks cause the crankshaft position sensor keeps going out. has anyone seen this before?

Welcome to the forum!

I heard of them go once but usually a new one will cure it. Maybe the dealer is cranking it down to tight? Or it could be a defective part. Post back if it goes out again.

Mine went out twice. First time they replaced it under warranty. The second time they could not findout why the truck would not start. They spent two days on it and it would not throw a code. It turned out my edge chip was the problem, they took it out and it started right up! We told them to throw the chip in the trash and it has not had a problem since!

thats the thing, its stock. i think the mech is just to damn lazy to trace it and see wtf is really going on. luckily i still have the warranty.

ok so dealership finally got it. there were a few wires that had chaffed thru and were shorting out the sensor. figures.

good to hear should hook up in dewitt daily

I was gonna say it sounded like a subpar mechanic who didnt want to trace wires. We all hate doing it from time to time, but if youve had to replace that many sensors its time to look elseware.

I just upgraded to EFI Live. And I am still waiting for my tunes. But When I tried to start the truck after unhooking the Edge. It wouldnt start. Crankshaft position sensor. I think the edge blew it. Now it only runs with the Edge hooked up. U have any more info about this?

Mine would only run without the Edge. When the Edge was hooked up it did not run so we told the shop to throw the F'N thing away and it has ran ever since!
