OL Multimeter Reading: 89 300E

Am getting an OL reading from my diagnostic port X11. Where should I be hunting? It is not constant, but when it does it, my vacuum gauge dips and moves toward the red.

Thanks everyone.

I am checking the voltage at pins 2 and 3, in setting the air/fuel ratio via voltage output.

A meter reading overload is set on too low a range. Step it up to the next higher range. If it is on auto-range, set it on a manual range where it will not indicate overload. It may be helpful for an intermittant condition to use an old analog meter.

Steve, thanks for the tip. I still get OL at cold start ups ( now getting contant reading ) until engine warms up a bit. There's got to be a breakage in connection somewhere. Any ideas where??

If you set the meter manually to a range where 12V is on-scale, e.g. 32 vdc f.s., you won't get 'OL'. What meter are you using? Note too that loop control via monitoring the O2 sensor does not occur until the O2 sensor warms up. Until then, your diagnostic reading may not be valid.

gotcha. i'm using this mastercraft brand digital multimeter, a canadian brand which you may not heard about but its got the neat functions. i've set it at the wrong range which may be the reason why i'm getting the OL reading. cheers!
