How to check codes on a '90 740 GLE?
Got a check engine light, and was wondering how to check the codes, as well as clearing them. I see a little box bolted to the shock tower with that looks to be a diagnostic type thing. Is this it?
I have a feeling it's a Mass Air code because looking in the service records over the years, it seems that it popped up about 8 separate times. Sensor was replaced numerous times as well.
