I got a 1990 2.9 burned resistor on eec pcm board. Im really wondering what would of caused this

 

[SenorNoob]

Is it traceable back to any of the pins on the connector?

Thanks Ill try my best to see. I was thinking of ohm ing it out on board just not sure if the minor voltage from meter would or could damage circuits? Im no electronic specialist. Great idea though

I wouldn't think so, especially on something this old. Yours looks to be very similar to my 92 PCM. That's a 1979 designed Intel 8061 at it heart. Pretty robust. Designed specifically for automotive use with voltage spikes and sags.

Now if you had an old Simpson meter or something...

Thanks for the help. I ended up replacing eec-vi. Pcm. And all good runs now
