The C1028 code indicates an issue with the voltage supply to the brake booster pressure sensor, which is crucial for proper brake system operation.
The brake booster pressure sensor monitors the pressure within the brake booster. This sensor requires a specific voltage to function correctly. If the supply voltage is out of range or interrupted, the sensor may not provide accurate readings, affecting braking performance.
• Illuminated brake warning light
• Reduced braking performance
• Unusual brake pedal feel
• Faulty brake booster pressure sensor
• Damaged wiring or connectors
• Blown fuse in the sensor circuit
