What is MID 104:
MID 104 refers to an issue with the Turbocharger Boost Pressure Sensor. The ECM is receiving an incorrect signal from the sensor, which may cause poor engine performance, as the boost pressure will not be managed correctly, leading to inefficiency or loss of power.
Why This Happens:
- Faulty turbocharger boost pressure sensor.
- Shorted or damaged wiring in the sensor circuit.
- Loose or corroded sensor connectors.
- Low or high boost pressure due to a malfunctioning turbocharger.
- ECM failure to interpret the sensor’s data.
How to Fix It:
- Inspect the turbocharger boost pressure sensor for damage.
- Test the sensor’s voltage and resistance to verify it is within specification.
- Check the wiring and connectors for visible damage or corrosion.
- Replace the faulty turbocharger boost pressure sensor if necessary.
- Inspect the turbocharger system for any mechanical issues.
How to Avoid It Before It Happens:
- Regularly inspect the turbocharger boost pressure sensor and wiring.
- Perform routine maintenance on the turbocharger system to ensure optimal performance.
- Keep connectors clean and corrosion-free.
- Use diagnostic tools to monitor turbo system performance.
- Clue’s Equipment Maintenance services help track turbocharger performance to ensure optimal engine health.
