What is ECU code C3139(83)?

I have this code on a 06 Chevy Malibu 2.2L LT, I believe this is some sort of electrical issue related to possibly the wiring harness or sensor or chassis, however I have no where to start.

    There is no C code in the 3xxx range.

    Re-check and then Google.

    There is a fault with the brake booster sensor/sensor wiring or the brake booster has a leak if you have to press harder when braking. Try replacing the sensor and clear the codes with a scan tool or disconnect the battery for an hour.  

    No luck, see a mechanic with a dealer level scanner.

    "“C” codes point to chassis problems, including braking, steering, or suspension issues"
