(SOLVED!) Could use a little help-cam sensor, (or at least I thought it was)
Sorry, this post will be a little long.
So last Tuesday morning I left for work at 5:00am
Got about 4 miles from home and the car starts cutting out and running like crap.
I get to a safe spot to pull over and stop and the car dies.
So I go to start it up again and it runs for about a minute, but it seems like its running on 1 or 2 cylinder and then dies. again
So I sit there for a couple minutes, gather my thoughts and then figure its time to try to get a tow truck.
Then I decide to try starting it one more time and it fires up and seems to be running normal now. Not missing any more and running smoothly. So I put it in gear and start to go. It seems fine for about 50 feet and then it starts running like crap again and as soon as I pull over, it dies and now it will not start again at all. So I get it towed home and drive my truck to work.
Forgot to grab my laptop, which has the VCDS on it, from work Tuesday night so I just did a couple initial checks when I got home.
Looked at the timing belt. Looks fine. No fraying and seems nice and tight. Checked to make sure the fuel pump in the tank is working. Also pulled the valve cover. Cam looks good no wear or chamfering on the lobes and the tappets look good from what I could tell.
So Wednesday, I brought home my computer and did the scan. came up with P3008, cam sensor out of range. Researching this site and some other ones, I found that you can unplug the sensor and it should start. Sure enough, I unplugged it and it started right up. Seemed to be running normal, idling smooth. So I decide to see if it will drive with the cam sensor unplugged. Drove normal for about 100 feet up the road and it started cutting out again. Same thing, felt like it was running on 1 or 2 cylinders. I pulled over and it died. I fired it back up and it was running like crap. I turned it off again, waited about a minute and fired it up again. This time running normal again, so I backed back up and back into my garage.
So I went ahead and ordered a new cam sensor. Didn't have a chance to install it until today. With the new sensor in, exactly the same symptoms.
Wont start with it plugged in and starts right up with it unplugged. Not going to try to dive it again.
One other thing. I checked the voltage and continuity on all three wires on the connector going to the sensor. I have 5 volt on pin 1, (power to the sensor). Pin 3 , (ground), is less than 1 ohm to ground and pin 2 is some number of K ohms to ground. So it looks like the wiring is OK.
So any ideas would be great.
I have a hard time believing that the timing belt has slipped a tooth since it starts and appears to idle normal with the sensor un plugged?
Hopefully someone has something else to try.
Thanks
