04-130 DIAGNOSTICS - ENGINE CONTROL SYSTEM

04 (f) Use a multimeter to measure the voltage
between the pin 3 of the oil rail pressure
sensor connector E04 and the ground.
Standard voltage

Multimeter connection
Standard value
pin
E04（3）-ground 4.75～5.25 V

Is the inspection result normal?
YES>To step 3.
No > Maintain or replace the harness.

3 . Check oil rail pressure sensor harness
(a) Ignition switch: OFF.
(b) Disconnect the battery negative cable.
(c) Disconnect the oil rail pressure sensor connector E04.
(d) Disconnect connector E01 of ECM.

(e) Use a multimeter to measure the resistance
between the pin 1, 2 of the oil rail pressure
sensor connector E04 and the pin 68, 69 of
ECM connector E01 respectively.
