The small tubes connecting the engine to the pressure sensor often become blocked with carbon soot . A leak in the rubber portion of these tubes is also a frequent point of failure.
Diagnostic data suggests that this code is rarely caused by a total failure of a major component like the turbocharger itself, but rather by the sensors monitoring it. renault 148e22
Use a diagnostic tool (like Launch or CLIP) to graph the Upstream Turbine Pressure against Engine RPM . If the pressure doesn't rise and fall in sync with the RPM, there is a confirmed blockage or sensor failure. The small tubes connecting the engine to the
