Pull up live data streams for your boost pressure and exhaust backpressure sensors. Monitor the values while revving the engine; if the pressure readings fail to fluctuate dynamically with engine RPM, you are dealing with a dead signal or an open pressure leak. Step 2: Check the Pressure Hose Line (Crucial for 1.5 dCi) Test the Sensor Voltage High temperatures behind the
