Injector Testing & Diagnostics
A diesel injector cannot be judged by eye. This category explains the tests that actually prove condition: flow and atomisation on a calibrated common-rail bench, static and dynamic leak-back measurement, coil and piezo electrical checks, and the coding values (IMA/ISA/C2i/C3i) that match a reconditioned injector to the ECU. It also covers what on-vehicle tests can and cannot tell you.
