Fuel Pressure Test
Special Tools Required
- Fuel pressure gauge 07406-004000B
- Fuel pressure gauge attachment set 07AAJ-S6MA150
- Relieve the fuel pressure (see FUEL PRESSURE RELIEVING )
- Attach the fuel pressure gauge set and the fuel pressure gauge
- Start the engine, and let it idle
- If the engine starts, go to step 5
- If the engine does not start, go to step 4
- Check to see if the fuel pump is running Listen to the fuel filler port with the fuel fill cap removed The fuel pump should run for 2 seconds when the ignition switch is first turned on (II) or engine start/stop button to select the ON mode
- If the pump runs, go to step 5
- '09 model without SH-AWD, '10 - 11 model: If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING )
- '09 model with SH-AWD, If the pump does not run, refer to the DTC TROUBLESHOOTING
- Read the fuel pressure gauge
Fuel pressure should be.
392-441 kPa (4.0-4.5 kgf/cm 2 , 57-64 psi)
- If the pressure is OK, the test is complete
- If the pressure is out of specification, replace the fuel pressure regulator, without SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ), with SH-AWD system (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter, without SH-AWD system (see FUEL FILTER REPLACEMENT ), with SH-AWD system (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure
