The MAP (Manifold Absolute Pressure) sensor sends data to the ECU about the pressure in the intake. If this sensor is clogged with oil or fails, it will send incorrect data, prompting the 148E22 code. 4. Turbocharger Failure

: Carbon buildup often blocks the small metal or rubber hoses leading to the upstream turbine pressure sensor, preventing it from reading correctly. renault 148e22
