OXY Sensor Reset

[RNajarian]

According to the maintenance records of my 1983 SC the oxygen sensor was replaced 4,000 miles ago. However, the red OXY sensor light is lit on the dash. Does anyone know how to reset this light. I've read that there is a reset switch on later 911 models behind the TACH but I do not see on on this car

Thanks for your help

There is a "button/switch" behind the tach/speedometer that needs to be pushed with a screwdriver. It is down low.

You will have to remove one of the above gages from the dash (wires do not need to be removed) to reset the O2 button.

Good luck

Thanks. EXACTLY where you said it was. I wasn't looking low enough. It reset and now no more annoying light. Thanks for your help.
