ELECTRICAL SYSTEM
ECU monitors various sensors, actuators, power amplifi er
circuits and detection circuits.When the intake pressure
is faulty, the engine may not be able to start or it may be
difficult to start. The common fault codes are shown in
the fault summary table.
Inlet pressure temperature sensor failure check:
◆ Check that the connectors are well connected.
◆ Check whether the wiring harness and sensor pins
are bent or deformed.
◆ Check the continuity of each pin.
