WTF???  Sensor light is now on where do I fix it?  Where does it go to what sensor under the hood?  Thanks for your replies in advance...

What kind and year zuki if its a carbed Samurai its like a service light and there should be a switch under the dash on the steering column to turn it off.

Yep, could be the SES nag light, or it may have thrown a code. But yeah, tell what year/make/model/engine/valves & tranny . Kinda hard to help with no idea what vehicle it is. 

It is a 86 Sammy 1.3 weber carbed 5 spd...  Thanks

There is a small slide switch under the dash next to the steering column.  Slide it to the opposite position and the light will turn off.

This is a "Nag" switch.  It turns on when the odometer increments to a multiple of some large value.  It is telling you to look at the owner's manual and perform maintenence at the indicated mileage.

Man I cant find that damn switch...

Howdy folks. I am new to this forum and a new Samarui owner. I have been reading over the Haynes manual that came with the car and don't really understand what the O2 sensor does on the carbed models. All I get out of the book is to change it when the light comes on at 80K miles. I also can not find that switch, I guess I am lucky it is not on right now. Mike

The o2 sensor relays how much oxygen is in the exhaust to the ecm.  The ecm uses this info to adjust the fuel mixture in the carb.

I dont know if its in the same place and my tracker but i found it next to the front left speaker pull the cover and the speaker and look to the right it should be right there. I just pulled my cluster and unplugged it.

To clarify, the switch - on a Samurai - is inside the dash mounted next to the steering column. You have to stick your head under the dash and look up.  it is attached to three lengths of wire that are about a foot long.  These wires are attached to the back of the gage panel unit so it is not mounted very far below the dash panel.

Get your flashlight out...
