P2376 Turbocharger Inlet Pressure Sensor B Circuit Low
Same as P2374 with the signal voltage below the plausible range. Boost control tracks commanded vs. actual manifold pressure; persistent deviation means wastegate, vanes, hose or actuator are not delivering the requested pressure.
Is it safe to drive with P2376?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
