• C1023
• C1024
This code means that there's a problem with the sensor that helps the car know how hard you're pressing the brake pedal.
The brake booster pressure sensor monitors the pressure within the brake booster and ensures it is within the expected range. If the sensor detects a pressure outside this range, it triggers code C1022.
The C1022 code is set when the Electronic Control Module (ECM) detects an issue with the brake booster pressure sensor's signal. This sensor is responsible for ensuring the brake booster is providing adequate pressure to assist with braking. The ECM monitors this sensor to ensure the brake system is functioning correctly.
• Inspect the brake booster pressure sensor and its wiring for damage.
• Check the sensor's electrical connections for corrosion or looseness.
• Perform a diagnostic scan to verify the code and check for other related codes.
• Replace the brake booster pressure sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set
