What is CID 12:
CID 12 refers to a problem with the vehicle's braking system, particularly the brake fluid pressure sensor. The ECM detects an issue with the pressure sensor, which could result in improper braking or a decrease in braking efficiency.
Why This Happens:
- Faulty brake fluid pressure sensor.
- Shorted or damaged wiring in the sensor circuit.
- Low brake fluid levels.
- Malfunctioning brake booster.
- ECM failure to interpret sensor data correctly.
How to Fix It:
- Inspect the brake fluid pressure sensor for malfunction or damage.
- Test the sensor’s voltage and resistance to ensure proper functionality.
- Check for leaks and ensure brake fluid is at the correct level.
- Replace the faulty sensor if necessary.
- Inspect the brake system for additional issues such as malfunctioning booster.
How to Avoid It Before It Happens:
- Perform regular brake system checks and fluid level monitoring.
- Keep connectors clean and free from corrosion.
- Perform routine diagnostics on the braking system.
- Replace brake fluid and components as needed.
- Clue’s safety management services help track brake system health and prevent malfunctions before they affect performance.
