Fuel Pressure Regulator

On 1.0L, fuel pressure regulator is located on top of throttle body assembly. Fuel pressure regulator maintains fuel pressure applied to fuel injector at 23-31 psi (1.6-2.2 kg/cm² ). To test fuel pressure regulator, see FUEL SYSTEM PRESSURE TEST under BASIC FUEL SYSTEM CHECKS in appropriate BASIC DIAGNOSTIC PROCEDURES article.

On 1.3L, fuel pressure regulator is located on fuel rail. Fuel pressure regulator maintains fuel pressure applied to fuel injectors at 39-44 psi (2.7-3.1 kg/cm² ). To test fuel pressure regulator, see FUEL SYSTEM PRESSURE TEST under BASIC FUEL SYSTEM CHECKS in appropriate BASIC DIAGNOSTIC PROCEDURES article.

On 1.8L, fuel pressure regulator is located on fuel sending unit assembly, on bottom of fuel filter. Fuel pressure regulator maintains fuel pressure at 44-50 psi (3.1-3.5 kg/cm² ). To test fuel pressure regulator, see FUEL SYSTEM PRESSURE TEST under BASIC FUEL SYSTEM CHECKS in appropriate BASIC DIAGNOSTIC PROCEDURES article.
