Sworn to secrecy!

RSS
Dear Tom and Ray:


I have a 1983 Renault Fuego in which I need to replace the oxygen sensor. I have a Chilton's Repair and Tune Up Guide which shows the location of the oxygen sensor very clearly. My problem is that the oxygen sensor warning light has to be reset, and that's where I am lost. The guide states "to turn off the indicator lamp after the sensor has been replaced, remove the indicator switch cover. Turn the square head button one quarter turn counter-clockwise, toward the stamped '0'." Where is this indicator lamp switch cover located?? Your assistance will be greatly appreciated.
Ruben

RAY: Sorry, Ruben. To get the top security clearance required to do emissions work, we have been sworn to secrecy regarding oxygen sensor warning lights.

TOM: They keep it a secret on purpose. They don't want people like you simply resetting the warning light without having the emissions system checked out. Even replacing the oxygen sensor isn't enough. They really want you to have the thing looked at every 30,000 miles to make sure you aren't causing more than your fair share of pollution.

RAY: So you have three choices, Ruben. You can spend the next 15 weekends searching high and low until you find a little square button with a "0" next to it. You can use the old "black tape solution" and cover up the warning light so it doesn't bother you. Or you can do the right thing, and take the car in for emissions service, which is what we recommend.
