At Idle Speed	490-519 kPa (5.00-5.29 kgf/cm 2, 71.1-75.3 psi)

Result

If the fuel pressure is beyond the specified value, replace the fuel pressure regulator (part of the fuel tank unit) .
If the fuel pressure is below the specified value, the cause may be one of the following:
- Fuel leak
- Fuel Tank Unit/Fuel Filter Components Parts

	- Abnormal the fuel pressure regulator (part of the fuel tank unit)
	- Plugged the fuel filter (part of the fuel tank unit)
