What is CID 902:
CID 902 refers to a problem with the vehicle's braking system, specifically related to the brake fluid pressure sensor. The ECM detects a malfunction in the sensor, which can affect brake performance and vehicle safety.
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 process sensor data correctly.
How to Fix It:
- Inspect the brake fluid pressure sensor and its wiring for 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 or malfunctioning brake components.
- Perform a diagnostic check to ensure the brake system is operating correctly.
How to Avoid It Before It Happens:
- Regularly inspect the brake system and fluid levels.
- 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 track braking systems and prevent issues before they affect vehicle performance.
