What is MID 97:

MID 97 relates to a fault with the Turbocharger Boost Pressure Sensor Circuit. The ECM detects an out-of-range signal from the sensor, which can affect the turbocharger’s boost regulation, leading to poor engine performance or inefficient fuel economy.

Why This Happens:

  • Faulty turbocharger boost pressure sensor.
  • Shorted or damaged wiring in the sensor circuit.
  • Loose or corroded sensor connectors.
  • Malfunctioning turbocharger affecting boost pressure.
  • ECM failure to interpret the sensor’s signal.

How to Fix It:

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

How to Avoid It Before It Happens:

  • Regularly inspect the turbocharger boost pressure sensor and wiring.
  • Perform routine turbocharger maintenance.
  • Keep connectors clean and corrosion-free.
  • Perform diagnostic checks to monitor turbo system health.
  • Clue’s equipment maintenance services help monitor turbocharger systems and prevent issues before they affect engine operation.
