Hello,
I have just bought a '82 280Z with a new engine and transmission...Just a few days after I bought the car, the SENSOR light comes on and stays on...Will some of you Datsun/Nissan lovers explainn to me what this light means, what causes it to go on, what I can do to gettt rid of it, and what can I do to prevent it from coming back on again.

Thanks & regards,

P.S.
If you could, please email me a copy of your replies to: [email protected]
as I might forget about visiting this site in a few days..

I used to have an '85 Sentra (don't laugh) and it had a sensor light also. It is tripped by the mileage, at 60k miles it went on, indicating you're supposed to take it to the dealer and get the oxygen sensor checked. I ignored it, drove it another 120k miles (yes, 120,000) before I sold it, still running beautifully. Did you recently pass some mileage point? 60k, 90k miles? Something like that? If it bothers you, take it to a dealer and have them turn it off, or take some electrical tape and cover it up.

The sensor light is reminder to check/replace the o2 sensor. The light is tripped by the odometer. to turn the light off remove the panel under the passenger side dash(the one with the light on it) look for a yellow wire with a green lione on it. there should be a connector right there. just disconnect the connector and the light will go off.

hope this helps you out.

YES...now I remember! I was fixing the stock stereo (82zx) and I happened to open
that panel. I saw two wires not ocneected, and since they were the only two wires around, I connected them.

My question though is, how do I make the system turn the light off itself? Should I change the o2 sensor? What?

Re: SENSOR light is on!How to turn off?

The light is tripped by a switch in the odometer it will not automatically turn off if you replace the o2 sensor. Either disconnect the wire or rip out the dash and adjust the switch on the odometer so it is always closed.
