Code C122A Description
The C122A code indicates a problem with the brake booster pedal force switch circuit in a vehicle. The brake booster is a component that helps amplify the force applied to the brake pedal, making it easier for the driver to stop the vehicle. The pedal force switch is a sensor that detects the amount of force being applied to the brake pedal. When this sensor malfunctions or the circuit that it is connected to has an issue, the C122A code is triggered.
Common Causes of C122A
- Faulty brake booster pedal force switch
- Damaged wiring harness
- Loose or corroded electrical connections
- Problem with the brake pedal assembly
- Water or moisture intrusion into the sensor
Symptoms of C122A

- ABS or ESC warning lights illuminated on the dashboard
- Difficulty stopping the vehicle
- Inconsistent brake pedal feel
- Decreased braking performance
How to Fix C122A
- Diagnose the issue by performing a thorough inspection of the brake booster pedal force switch circuit.
- Test the brake pedal force switch to determine if it is functioning properly.
