What is MID 50:
MID 50 refers to an issue with the Fuel Rail Pressure Sensor Circuit. The ECM detects an abnormal signal from the fuel rail pressure sensor, which could lead to incorrect fuel pressure readings and poor engine performance, such as stalling or poor acceleration.
Why This Happens:
- Faulty fuel rail pressure sensor.
- Shorted or damaged wiring in the sensor circuit.
- Loose or corroded sensor connectors.
- Low fuel pressure caused by a malfunctioning fuel pump.
- ECM misinterpreting the sensor’s signal.
How to Fix It:
- Inspect the fuel rail pressure sensor and wiring for damage.
- Test the sensor’s voltage and resistance to ensure it is within specification.
- Check connectors for tightness and cleanliness.
- Replace the faulty sensor if necessary.
- Inspect the fuel system for any low pressure or pump issues.
How to Avoid It Before It Happens:
- Regularly inspect the fuel rail pressure sensor and wiring.
- Perform routine fuel system maintenance.
- Keep connectors clean and corrosion-free.
- Perform diagnostic checks to monitor fuel system health.
- Clue’s Fuel Management services proactively monitor fuel systems to detect issues before they affect engine operation.
