Faulty Injector?

Recommended Posts

My Auris has a quite noise engine (diesel knocking) on 2000 rpm. Could it caused by injector?

Injector feedback values was in -0,5 to -0,7 on injectors 1, 3 and 4, injector number 2 was +2.

Max feedback value is +3 . Is the injector number 2 faulty?

All the injectors are within specification however one injector is not injecting quite as much fuel as the others which maybe causing a knocking noise. Before replacing injectors ( which may have to be done as a set if you have the obsolete phase 1 set ) try using some quality fuel injector cleaner and getting a Toyota dealer to reflash your engine ECU with the latest software available as this includes improvements in the injector mapping programme.
