Camshaft position sensor probs
I posted this in the v10 section with few answers so ill try here too. I have a 2002 e350 v10 and am getting a p0340 code. Only getting .3v from the pcm (wire cut a few inches from pin connector) to ground or to sensor return wire. Got continuity through pcm connector using paper clip (about same size as pin). Ive even put another pcm in and same results. What could be keeping the pcm from sending voltage out. Im assuming that .3v is not the correct voltage i should by recieving. right? Oh ya truck runs ok as well and trips the light after a while but still idles and drives fine.

Here's a diagram.

From what I can tell so far, this sensor is somewhat of a generator, and generates a frequency depending on the speed of the camshaft. So I am not sure you are going to get a voltage from the PCM. If it was a powered sensor, it would have 3 wires, power, ground and signal. If the link below will work, it shows a table that at idle you should have 6 hertz signal and at 55 mph you should have a 16hz signal on pin 85. So you might need a scope to read that.

I have a funny feeling the last link is not going to work, so if you want to go to Autozone's site, register, then plug in your van and click on "repair guides", they have pretty good diagrams and info in there. Here is the path to the last link I was in with the chart.
