ERIKC DLLA 152P 865 denso diesel common rail nozzle DLLA152 P865 spray nozzle for 095000-5510

FAQ: Failure Analysis?

ERIKC Answer: Symptoms: The starter and the engine both have a normal starting speed, but they do not catch fire; or sometimes they can catch fire after many long starts.

Cause of failure: There is air in the fuel line.

Fault nature: mechanical failure. Treatment method: The fuel pipeline exhausts air.

Failure Analysis: The State III vehicle adopts a common rail system, and the air discharged by the oil circuit is relatively difficult. Often, the operator feels that the air is excluded from the air cleanliness. Actually, it has not been thoroughly cleaned. According to the actual use situation, the oil pump return bolt should be released to discharge the air. If necessary, the high pressure fuel pipe can be loosened, and the starter can be used to drive the engine idle to discharge the air; if only the deflated screw of the fuel filter is released Exhaust air may not be easy to completely remove the air in the fuel pipeline, which is more laborious.

FAQ: Failure Analysis?

ERIKC Answer: Symptoms: The starter and engine both have a normal starting speed but do not catch fire.

Cause of the fault: The ECU has a fault code.

Fault nature: electrical failure. Solution: Clear the fault code.

Failure Analysis: This vehicle is normal from the mechanical inspection, diagnosed with the diagnostic instrument found "water temperature sensor", "rail pressure sensor", "accelerator pedal" and some other fault display, clear the fault code, the engine starts smoothly. This situation is estimated to be the maintenance or operation personnel's operation of plugging and unplugging the connector of the electronic control system. The system will generate a fault code and store it in the ECU. The system will have a protective effect and will limit some functions or even fail to start.
