Just pulled PO336 Code....

[1 ALC]

The yellow check engine code came on and I used a scan tool to pull out a "PO336" code. The truck is running fine.



Should I replace the "Crankcase Postiion Sensor" immediately, or is it not serious?



Could the Superchips box (same as Edge EZ) could have caused this?



Thanks.

I replaced mine because of an erratic tach, but the truck ran fine. If yours isn't doing anything different I'd say let it go until something changes.
