Connect a dedicated diagnostic scan tool to the vehicle's OBD2 port. Check if code 148E22 is accompanied by performance code . 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)
