How To Tell If You Afm Is Shagged?

[RB25 SKYLINE]

Hi guys just wondering if there is a figure to test the resistance of a AFM or a way to tell if its shagged?i recently gave mine a clean and the car has been running strange ever since it doesnt seem to be delivering enough fuel so i want to test it to try narrow things down a bit any help would be great cheers

When mine was dying, its voltage was doing funny things at idle and low loads. Didn't hold stable output, was dropping voltage to 0v then back to normal rapidly. You may want to monitor AFM voltage output.

You may want to monitor AFM voltage output.

Easiest way to do that is via the CONSULT port.

Where do i find the consult port?

Its next to the fuse box, but you need a cable and software to read it (or a mate with cable + software . Search here if you want more details.

The very simplest way is to borrow a known good one to try.

Just crack it open and try soldering the plug pins on the board, dry solder joints are a common problem and break when you disturb them. If the hot wire or board fails it usually won't work at all.
