C0022 code: Brake Booster Solenoid
Code C0022 is named in 3 US owner complaints. Models: 2, model years 2011–2012.
What the code means
Brake Booster Solenoid. Generic meaning per SAE J2012 (the same for all makes).
How to read C0022: 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 022 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.

What to do if an auction car has this code
- Inspect the wheel and suspension on the impact side: the wheel speed sensor is often damaged together with the hub or knuckle.
- Check whether the ABS and ESC lights stay on after start-up.
- After replacing sensors or the hydraulic unit, bleeding and scan tool adaptation may be required.
What owners report
Excerpts of owner complaints in the original wording. Owner statements not verified by the regulator; personal data removed.
Brakes were spongy and could barely stop the car. Trouble codes c00002 C0022, C1012, U0415 and u30000 codes showed. My mechanics checked my mechanical brake systems and all were fine and found no problem. My mechanic thinks a computer problem is the issue.
But was easier to stop since repair from previous week on 2/16/15. Dealer recorded abs system test, C0022, abs pinpoint test p, circuit test brake booster solenoid, intermittent brake booster solenoid operation per ppt p6, replaced the brake booster assembly per ppt p7.
