Why Unit Injectors Are Replaced
On the D12A the unit injector works at high pressure and a heavy duty cycle. The control valve and nozzle wear over time, so the injected quantity drifts from the value the ECU expects. Drivers notice hard starting, a rough idle, falling power and black smoke, and the ECU eventually stores a correction-limit fault.
Fitting Notes
- Confirm the number on the original unit before ordering; unit injectors are matched to the engine variant.
- Renew the copper washer and O-rings and keep the injector bore clean.
- Recode the injector where the engine management requires it.
