06 jetta tdi camshaft position sensor issue

[tf06jettatdi]

hi all,

having a issue starting my 06 jetta tdi. i have been looking through post and found one on another issue but suggested to disconnect the camshaft position sensor if you cant start you engine...i did that and it allowed me to start the engine...it took a little longer to start but it did start....so now i am trying to figure out what is wrong...is my camshaft position sensor bad?...is there a way to test the sensor or wiring....please help...

thank you
tom

Was the rear main seal replaced or removed recently?

Do you have VCDS? You can use that to check camshaft sensor. Possible things that could cause a problem other than sensor are timing belt, cam wear, wiring problem.

no on the rear main seal...i do have and VCDS
what group in the VCDS do i check on?
what values am i looking for in testing my camshaft position sensor?

camshaft and lifters replaced 20k ago
timing belt replaced 30k ago.

thank you
tom

this is the error when i have the cam position sensor plugged in...and wont start

[Ol'Rattler]

The part the cam sensor sees is what the cam sprocket bolts to. As I recall the sensed part protrudes slightly over the top of the valve cover.

Is it possible you damaged a wire or knocked the sensor out of position or damaged it or the part that is sensed, somehow when changing the cam?

[tf06jettatdi]

the cam was replaced 20k miles ago and the car was starting just fine till a week or so ago....i have to unplug the cam shaft position sensor to get the car to start now....is there a way to test the cam shaft position sensor? is there a way to test the wiring? voltages? resistences?

VAG Error Code: 19464
EOBD II Error Code: P3008

Fault Location:
Camshaft position (CMP) sensor - signal limit exceeded

Possible Cause:
Insecure rotor.
Camshaft alignment.


VAG Error Code: 19463
EOBD II Error Code: P3007

Fault Location:
Camshaft position (CMP) sensor - no signal

Possible Cause:
Air gap.
Insecure sensor/rotor.
Wiring.
Camshaft position (CMP) sensor.

As taken from my Free EOBD II Error Codes software

brings up that crank angle sensor and camshaft sensor are both Hall type sensors.

Testing CAM or CamShaft Position Sensor Hall Effect Type

thanks Keith, will test sensor & post findings.

test results

pin 1 to pin 2 = 4.95 volts

ping 3 to earth = .45 volts on average

so it looks like i am within what they said on the video....can my timing be off...i am going to check that tomorrow
