1. Disconnect the negative battery cable.
2. Connect a pressure gauge between the fuel filter (high pressure side) and the fuel distributor.
3. Connect the negative battery cable.
4. Start the engine and let it idle.
5. Carry out the intake-air system inspection.
6. Measure the fuel line pressure.
Specification: 210-330 kPa (30-48 psi)
7. If not as specified, carry out fuel system inspection.
8. Disconnect the PRC solenoid valve connection.
9. Apply battery positive voltage to terminal A and ground terminal B of the PRC solenoid valve.
10. Measure the fuel line pressure.
Specification: 280-330 kPa (41-48 psi)
11. If not as specified, inspect the PRC solenoid valve.
12. If PRC solenoid valve is OK, replace the pressure regulator.
