Komatsu pc240lc-10 error code L03 CA2554

Help! I've got a komatsu pc240lc-10 that has thrown the code L03 CA2554 twice. The machine even went through its regen cycle and right afterwords it threw the code again. I'm helping my operator from several hours away and cannot seem to find any information about this.

    Clean the tube that goes from the exhaust manifold to the sensor.

    Thanks for the help on this. I'm going to try cleaning that tube for as of now, two regens seemed to clear the code. I'll keep you posted on my findings.
