What is MID 19 & How to Solve It?

What is MID 19:

MID 19 refers to an issue with the Turbocharger Boost Pressure Sensor Circuit. This fault code is generated when the ECM detects an abnormal signal from the turbocharger boost pressure sensor, leading to improper boost pressure regulation and poor engine performance.

‍

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 misinterpreting the sensor’s data.
  
  

How to Fix It:

1. Inspect the turbocharger boost pressure sensor for damage or malfunction.
   
2. Test the sensor’s voltage and resistance to ensure it matches the manufacturer’s specifications.
   
3. Check wiring and connectors for visible damage or corrosion.
   
4. Replace the faulty turbocharger boost pressure sensor if necessary.
   
5. Inspect the turbocharger system for mechanical issues or performance problems.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the turbocharger boost pressure sensor and wiring.
  
• Perform routine turbocharger system maintenance.
  
• Keep connectors clean and free from corrosion.
  
• Perform diagnostic checks to monitor turbo system health.
  
• Clue’s Equipment Maintenance services track turbocharger systems to monitor boost pressure and prevent related issues from affecting engine performance.
