How to install Camshaft Position Sensor?

[Blkdawdg]

Anyone know the steps to installing a camshaft position sensor? I went to the dealership this morning (Maxwell Dodge in Austin) and they abruptly told me that I don't have a camshaft position sensor. So I turned around and walked right back out the door.



Anyway, I believe that I know where it is located on the truck and I'm on my way to go pick one up right now, so I just need to know if the crank needs to be @ TDC or what?



Thanks

2000 Service Manual



The camshaft position sensor(CMP) is located below the fuel injection pump. It is attached to the back of the timing gear cover housing.



Removal

Disconnect both neg cables

clean area around CMP

Disconnect electrical at CMP

Remove CMP mounting bolt. Bolt head is female hex

Remove CMP from engine by twisting and pulling straight back

Discard CMP o-ring



Installation

Install new o-ring to CMP. Apply clean engine oil to o-ring

Clean are around mounting hole

To prevent tearing o-ring install CMP into gear housing using a twisting action

Install mounting bolt and tighten to 15 ft lbs

Istall electrical connector

Connect batt cables



Straight out of the service manual. Tell the dealer its on page Fuel System 14-113 of the 2000 manaul and its also in the 2001 Supplement.

Some trucks have Crank Position sensors and some have Cam position sensors. Yours probably came with a Cam sensor and the techie at the dealership doesn't realize this If your truck was supposed to come with a cam sensor or it fell out I doubt your truck would run at all.

Sensors

Up to 2001 the engines had both CAM and CRANK sensors.

From 2001 up they have only the CAM sensor.



Engines with only the CAM sensor use the sensor output of the VP as engine reference signal instead of the crank sensor.



Anyway, it's very hard to unplug the connector from the cam sensor, let's alone say change it. It'll be a PITA! That thing is completly hidden by the VP-44... .

Good luck.

What year is your truck? I didn't say nuthing bout the crankshaft sensor since I couldn't remember your trucks year.

For info purposes will you post part number and price when you get one? I am sure one day another member will find it handy.



Thanks

I have a 2001. 5 so I hope that I only have to change the camshaft position sensor since that's the only one that I bought.

The Cummins part number is: 3408430; and I paid 35. 00 for it.

Say a prayer for me because I'm going to tackle this thing without removing the VP.

 

[Blkdawdg]

PITA!

Changing the CPS has to be the worst thing that I've had to do on my truck. I look like I've been in a cat-fight. I've got scratches all the way up to my elbows. It took me right @ 2 hours to remove one bolt and the sensor and then replace. Removing the sensor took about 30 seconds... . the darn bolt holding the sensor in took the other 1 hour, 59 minutes and 30 seconds.



But at least it's done and the truck is working fine. Thanks to everyone for their help.

Blkdawge, did you tach quit working or something? Why did you replace yours?

[Blkdawdg]

Yep!

The tach would only work intermittently (spelling?) and whenever the tach wasn't working it would make the truck have a REALLY lopey idle (the whole truck would rock, hard!)

I have a '99 model, so it should have both the cam and the crankshaft position sensor, if one of these were to go out would the engine quit and not start. Mine died the other day and I cannot get it started, service says it is the injection pump, but before it died my tach was doing the same thing that Blkdawdg's was doing, dropping to zero and then coming back up again with the check engine light on. I am wondering if it is not the injection pump, but one or both of these sensors?

 

[Blkdawdg]

I hate to be a bearer of bad news but when mine was acting up, I actually unplugged the CPS and cranked the truck and it started right up. If you're having a starting problem, unfortunately my guess would be that you either have a bad injector or your injector pump bit the dust.
