Checking wiring and terminals

The cause of the diagnostic trouble code (DTC) was loose connections in the injector and / or engine control module (ECM) connectors. Check the connectors for loose terminals and contact resistance and oxidation according to Contact resistance and oxidation .

Check the cable between injector connector terminal 2 (control module side) and engine control module (ECM) terminal 59 (EFI-115), terminal 90 (EFI-125), terminal 60 (EFI-135) or terminal 89 (EFI-145) depending on the diagnostic trouble code (DTC) stored, for an open-circuit according to Open-circuit, permanent faults .

Remedy as necessary.
