Ok P2106 has to do with the EGR system module to do more diagnostics on this you will need a scan tool and maybe a digital multi meter.
C1230 is the commonly the rear speed sensor on the top of the differential or one of the front speed sensors. With a digital multi meter this can be tested to see which it is. Let me know what you want to do. I will walk you through the tests.
