I just recently had the service engine soon light go on in my car..... i thought it was something minor . . the engine made a little sqweaky noise. so i replaces the oxygen sensor b4 the catalytic convertor and the light still hasnt turned off. My car has about 55,000 k . Does anyone knows what the problem is and what can i do? a friend of mine told me that nissan has this light go n after u pass 55.000k if so, how can i reset the light or turn it off? thx

 

what kind of squeaking noise?

 

The sqeaeking noise is not related to the problem. my dad says its a belt or something . . . .

 

Get the code pulled, then we can help you out more...

Advance/Autozone will pull the code for free.

 

even if u solve the problem, don't u have to reset something to make the ses light go off?

 

Unplug the battery for 15 minuts then it will clear. If there is still a problem with the car it will turn back on after about 100 miles or so.

 

Steps to take...

1.Pull out the speedo cluster
2.Pull the plastic cover off.
3.Place a small amount of elect tape over the light
4.ReInstall and your done
5.No more SES light, problem solved.

 

Ha Ha i like this .

 

once them lights come on they're like dummy lights, you can get it reset but it will come back on... sometimes if you don't close your fuel cap tightly you can get some air in the tank and that can cause it to come on too.... pull the fuse

 

Reason the CEL comes on for a gas cap- all 97 and up cars had to be equipped with evaporative emissions systems. What this means is... the fuel vapors in the gas tank where escaping and going into the atmosphere and polluting our planet- according to the EPA. So what happens is the gas tank is pressurized and the gases are now burned by the engine. There are a series of valves and solenoids in the system, with lines runing from the fuel tank to the EVAP canister under the car, then from there to the intake manifold. When the gas cap is loose or U get an EVAP code, the engine will run the same way it used to, but the CELight is on so ya fix the EVAP system. Sometimes fixing it can be kinda tricky as it might be a leak at a stupid O-ring, Solenoid, or a broken line.... EVAP sucks. Long live OBD I.
