P0335
2014 f450, I've got p0335 everytime the key is on, the long crank and irratic idle. I've got 5 volt to the green/violet wire to the sensor, I've checked continuity from each wire on the connector to the pcm. I've tried a new CKP with no luck. The signal return wire yellow/orange, I'm getting 4.8 volts out of the pcm. All wires ohm good from the pcm connector to the CKP sensor. I'm unsure of why I'm getting voltage out of pcm on the signal return. If anyone has any advice I would greatly appreciate it. Thanks

I did a quick search on the forum for that code, and came up with these (if they might help):

One issue was resolved with tracking down a faulty wiring harness connection, another with replacing bad crankshaft position sensor, and one with replacing both batteries (which really should be the first thing attempted if they're more than three or so years old).
