How to diagnose a diesel injector fault?
The fault returned was ‘P0263 Injector cylinder 1 – Drift’, indicating an injector related fault. STEP 2: The technician checked all of the injector’s back-leakage using the Delphi sealed rail kit in order to identify which injectors were not performing to specification, and to confirm correct levels of rail pressure.
How do you test a Delphi diesel injector?
The injectors were sent to a local Delphi Diesel Centre. The Delphi Diesel Centre tested the injectors on a Delphi-authorised test bench to confirm which injector was at fault. This included electrically testing the injectors for resistance and insulation failures.
How is the C2I code printed on an injector?
In this case the one repaired injector was, once again, put through a complete test procedure on an authorised test bench and recalibrated with a new C2i/C3i code which was printed onto a label and attached to the injector body. The new calibration code is critical for the operation of the repaired injector.
Why do you need a new calibration code for a diesel injector?
The new calibration code is critical for the operation of the repaired injector. When fitted to the engine, it allows the software within the ECU to accurately control the injector’s fuel delivery and switching times according to the specific parameters and performance for the vehicle.
Where does the fuel injector go in a diesel engine?
Fuel injectors are small electrical components that are used to deliver fuel via a spray directly into the intake manifold in front of the intake valve in a diesel engine.
Who are the original manufacturers of diesel injectors?
That is why Lucas, one of the original names in the development and manufacture of high pressure diesel fuel injection systems, has launched a range of remanufactured injectors and pumps for common rail applications, covering in excess of 80% of the vehicle parc.
What happens if the fuel injector is not working?
Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.
How long does a diesel fuel injector last?
The average lifespan of a diesel fuel injector is around 100,000 miles. A typical fuel injector has two basic parts: the nozzle and the injector body. If either of these components gets clogged or damaged, it will compromise the entire performance of the vehicle. Here are the 5 most common symptoms of faulty diesel fuel injectors.
