DIAGNOSTICS - ENGINE CONTROL SYSTEM 04-219

(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.

Standard resistance

E04（1）- E01（68） ＜10 Ω

E04（2）- E01（69） ＜10 Ω

(f) Use a multimeter to measure the resistance
between the pin 1, 2 of the oil rail pressure
sensor connector E04 and ground
respectively.

Is the inspection result normal?
YES>To step 5.

No > Maintain or replace the harness.

5 . Replace oil rail pressure sensor
(a) Replace fuel pump booster assembly.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Confirm whether the fault code is still exists.

Is the inspection result normal?
YES>To step 6.

NO> Replace oil rail pressure sensor

6 . Check engine fuel pump booster assembly wire harness
(a) Ignition switch: OFF.
(b) Disconnect the battery negative cable.
(c) Disconnect the engine fuel pump booster assembly connector E11.
