Fuel Injectors N30, N31, N32, and N33, Checking

Fuel Injectors N30, N31, N32, and N33, Checking

The following test procedure is used to diagnose Fuel Injectors (N30, N31, N32, N33, N83, N84).

Electrical Test

Special tools, testers and auxiliary items required

‹› Multimeter.

‹›  Diode test lamp (12V).

‹› Wiring diagram.

Test requirements

‹›  The Fuel Injectors (N30, N31, N32, N33, N83, N84 ) fuses OK.

‹› The Engine Speed (RPM) Sensor (G28) OK, checking.

‹› Battery voltage at least 12.5 volts.

‹› All electrical consumers such as, lights and rear window defroster, switched off.

‹› Vehicles with automatic transmission, shift selector lever into position " P" or "N".

‹› A/C switched off.
