What the code means

Vacuum Sensor A/B Correlation. Generic meaning per SAE J2012 (the same for all makes).

How to read C0561: the letter C means chassis (brakes, ABS, steering, suspension); the second digit 0 marks a generic SAE code shared by all makes; the last three characters 561 identify the specific fault.

ABS/ESC codes: wheel speed sensors, the ABS hydraulic unit and pump, brake booster, pressure and yaw sensors. A hit to a wheel or suspension often damages the wheel speed sensor or its wiring, so on a damaged car this code is a reason to inspect the hub, knuckle and control arms, not just swap the sensor.

Gm still does not support and take responsibility for this issue -pulled the codes. The recent ones I've gotten are: C0899, C0561, P0017, P0011 last time this happened, it cost me over $1500 to replace all of the fuses/wiring. I am frustrated, yes. No, I don't have the money to fix this yet again.

Several hours later, the check engine light remained on, but the car drove normally -- straight to the repair shop, where it was deemed to need $2400 in transmission repair due to the following fault codes: P182E & C0561. They will replace the transmission mode shift sensor and the transmission control module.
Chevrolet Traverse 2010 · 2016-06
Started car up and message center flashes power steering, service esc. I get codes U2143, C0561 on scanner . Total loss of steering assist. This car is not part of recall on steering problem but it should be!
