DTC codes / P23xx · Ignition system and misfire / P2376
P2376 indicates that the powertrain control module (PCM) has detected an abnormally low voltage signal from the turbocharger inlet pressure sensor B circuit, which typically measures the pressure of air entering the turbocharger compressor. The PCM expects a voltage within a calibrated range, and a low reading suggests a short to ground, a faulty sensor, or a wiring issue.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
