Engine Output Power Reduction Of Hitachi Excavator

Jul 15, 2018

[fault analysis]

1 DTC:P0192 (scintillation code 245) common rail pressure sensor fault (low voltage)

(1) the main failure phenomenon:

(1) the engine may be stalled.

The output power is reduced.

(2) standby mode:

(1) the control of common rail pressure feedback stopped.

(2) limit the amount of fuel injection by 2 (multi point injection stop).

EGR stops.

(4) conversion of control to SCV mandatory drive.

Objective 80MPa.

2 DTC:P0193 (scintillation code 245) common rail pressure sensor fault (high voltage)

(1) the main failure phenomenon:

(1) the engine may be stalled.

The output power is reduced.

(2) standby mode:

(1) the control of common rail pressure feedback stopped.

(2) limit the amount of fuel injection by 2 (multi point injection stop).

EGR stops.

(4) conversion of control to SCV mandatory drive.

Objective 80MPa.


[extended reading]

3 DTC:P0182 (scintillation code 211) fuel temperature sensor fault (low voltage)

(1) main fault phenomenon: operating performance is affected.

(2) standby mode: fuel temperature default setting (start time: -20 C, Runtime: 70 C).

4 DTC:P0183 (scintillation code 211) fuel temperature sensor fault (high voltage)

(1) the main failure phenomenon: there is no special phenomenon.

(2) standby mode: fuel temperature default setting (start time: -20 C, Runtime: 70 C).
