    I bought an 08 kenworth c-15 cat 2 weeks ago. It keeps putting high crank case pressure code and derating engine. I have changed blowby filter, crank case pressure sensor, and still having problems. No visible blowby. Have had back to dealership twice, nothing shows up on computer.

    HELP!!

    I have a c15 to but do not know where that sensor is located. If the wiring harness is damaged the c15 sensors are designed to break instead of the ecm.

    Also remove the oil fill cap while the engine is running and check for blowby there as well.
