A P0092 code on your 2019 Chrysler Pacifica indicates a low voltage condition in the fuel pressure regulator control circuit. The Pacifica's efficient V6 requires proper fuel pressure regulation for optimal family transportation.
Pacifica Engine Configuration
The 2019 Chrysler Pacifica uses the 3.6L Pentastar V6 producing 287 horsepower. A plug-in hybrid version (Pacifica Hybrid) is also available with modified fuel system operation. The fuel pressure regulator solenoid controls fuel delivery to maintain optimal engine performance.
Low Circuit Interpretation
A low voltage reading indicates the PCM detects reduced voltage in the fuel pressure regulator circuit. This typically results from a short to ground—either in the solenoid coil, wiring, or connector. The short creates an unintended current path that reduces circuit voltage.
Diagnostic Steps
Locate the fuel pressure regulator solenoid on the Pentastar V6—it's in the fuel rail area. Disconnect and measure solenoid coil resistance (check specs, typically 5-15 ohms). Test for low resistance between circuit wires and ground. Inspect wiring for damage, particularly near heat sources or moving components.
Repair Requirements
A shorted solenoid requires replacement. For wiring shorts, locate and repair the damaged section. Use proper automotive electrical repair techniques. After repair, clear codes and verify proper fuel pressure control. Test drive the minivan to confirm smooth family-friendly operation has returned.
