Engine/Transmission (1998.5 - 2002) Camshaft position sensor

[Mutch]

I have been getting trouble codes 0341 and 1690. The tach drops to 0 intermittently, and power is reduced when it drops out. Of course this started the week after the truck rolled over 100k miles! I bought a new camshaft position sensor, part # 3408430. I found a lot of help on replacing the crankshaft position sensor (behind the starter) on 2000 and earlier 24v, but can't find any help on swapping the camshaft position sensor. Has anyone done this job? how hard / time consuming is it? I am leaving saturday for a week's trip and want to take care of it before I leave. Any advice is appreciated.



Thanks!

Your sign shows a 2001 truck.

The sensor behind the starter is the CRANKshaft sensor. Your truck does not have one! Last MY the Crank sensor was used is 2000. From then on only the Camshaft sensor is used.



As you correctly say, you need to change the CAMshaft sensor.

This one is located under/behind the injection pump (VP).

I've never had to change one, sure enough looks like a major PITA to get to the cam sensor. I think I've seen mention here on TDR that the sensor can be changed without removing the VP.

Based upon removing a CRANKshaft position sensor, CKP, from a 2000, behind the starter:

If you live in snow/salt country, expect a lot of rust around the sensor, making it interesting to remove. Expect to have to damage it severly, or destroy it getting it out, unless you are one of the lucky ones, who are able to remove it as the manual says!!!



Good Luck and allow more time than you would normally figure to handle rust if present :{

I know that my 2001 does not have a crankshaft position sensor, just a camshaft position sensor. Anyone out there that has changed theirs?

Drew; My camshaft position sensor also is bad. I have one sitting in the box on the dash and have been too chicken to change it. From what I have read you can do it without pulling the vp but you will spend 2+ hours getting the $&^&&! allen head retaining bolt out. I have BIG hands and have not yet figured out the easy way. I bought some metric ball end allen wrenches and thought I might fabricate a special tool to get in there. Let me know the trick if you do it. Rich

Thanks for the lead Ididntdoit, My manual is 2000 rev and does not show the CPS fix. Maybe I can get the wife or son to help with the access problem.

If you are good at standing on your head,disconnecting the wiring by braile where you can't get your hands and pulling out a sensor that has been cooked into place by 4 or 5years of heat cycles,it is a piece of cake

Other wise you would pobably be quicker to pull the vp and see what you are doing. Good luck

It would be faster to pull the vacuum pump/power steering asembly - you don't have to pull gears or injector lines to get them off. You can access the cam sensor easily this way. Just be sure to pick up a new gasket that goes between the vacuum pump and the engine gearcase.

If your vacuum pump is leaking (leaks engine oil between the vacuum pump and the PS pump), this would be a perfect opportunity to put in a seal kit.

This is what I did! I tried to change it and couldn't then my vacuum pump started to leak so when I took that out I changed the CPS.
