Fuel Pressure Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.

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 5.
- If the engine does not start, go to next step.
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 to ON (II).
- If the pump runs, go to next step.
- 2WD model: If the pump does not run, do the fuel pump circuit troubleshooting (see FUEL PUMP CIRCUIT TROUBLESHOOTING ).
- 4WD model: If the pump does not run, check for DTCs, then do the appropriate DTC troubleshooting procedure.
Read the fuel pressure gauge. The pressure should be 390-440 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; 2WD model (see FUEL PRESSURE REGULATOR REPLACEMENT ), 4WD model (see FUEL PRESSURE REGULATOR REPLACEMENT ) and the fuel filter; 2WD model (see FUEL FILTER REPLACEMENT ), 4WD model (see FUEL FILTER REPLACEMENT ), then recheck the fuel pressure.
