dtc 18
dtc 18
just scanned my car and this stored code came up. I looked at the service manual and am following the diagnostic guide bui don't have a injector tester which it seems like is required. i tested the resistance with my ohm meter or each injector and all are between 12.7-12.9. I'm going to pick up a noid light and try the tests it allows but i was wondering if there were any common causes of this DTC i should look for?
Check for +12V on the pink wire on each injector harness clip. There should be a constant +12V on the wire, with the PCM supplying the ground on the color/black wire to fire the injector. There are two fuses, one for each bank of injectors. Check those if you don't have power to the pink wires.
