1. Check the Rail Pressure Sensor Signals
1. Place the key switch in the ON position, and check the "Actual
rail pressure" and "Rail pressure sensor output voltage" on the
diagnosis tool data monitor.
2. Next, start the engine, change the depressed amount of the
accelerator pedal, and check the same items again.
NOTE
• When idling: Approx. 40 to 50 MPa (410 to 500 kgf/cm

, 5800
to 7200 psi)
During no-load maximum speed: 95.0 to 115 MPa
(969 to 1170 kgf/cm
2
, 13800 to 16600 psi)
• Reference value (service specification) has complete
linearity.
