What is CID 70:

CID 70 refers to an issue with the turbocharger boost pressure system. The ECM detects that the boost pressure is not within the expected range, which can result in reduced engine power, poor acceleration, and inefficient fuel consumption.

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 properly 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 it is functioning properly.
  3. Check wiring and connectors for visible damage or corrosion.
  4. Replace the faulty sensor if necessary.
  5. Inspect the turbocharger system for performance issues.

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 corrosion-free.
  • Perform diagnostic checks to monitor turbo system health.
  • Clue’s equipment maintenance services help monitor turbocharger systems and detect issues early before they affect engine performance.
