Solving the P0191 Code on Your Chevy Equinox: A Step-by-Step Guide

The P0191 code is an indication of a fuel rail pressure sensor circuit range/performance malfunction in the Chevy Equinox. This code is triggered when the Powertrain Control Module (PCM) detects a difference between the actual fuel rail pressure and the desired fuel rail pressure. The PCM will then store a P0191 code and turn on the Check Engine Light. Common causes of this code include issues with the fuel pump, wiring, or connectors; clogged fuel filter; faulty fuel pressure regulator; faulty fuel rail pressure sensor; or poor connection at the PCM. To properly diagnose and repair this issue, a qualified technician should be consulted.
