Last night I was driving around and the light came on. I checked all liquids and everything seems full. The only thing I notice is that it has a strong smell of gas. It's Sunday so everything is closed so I can't go to the garage, and with Christmas it might not even be open tomorrow. I'm just wondering if anyone has any ideas what the problem might be and about how much it will be to fix.

i dunno but if you smeel gas, is it just running rich cause your o2 is bad? just an idea. Does the car run funny, or act different in anyway. Try reseting your ecu, and see if it goes out and stays out. Not uncommon for it to come on for something little or nothing. This is how to reset your ecu. Takes under 10 minutes.

Find the computer(Behind the plastic piece by the passenger foot Pull it out Turn your key to the on position You will see a flathead screw looking bolt on 1 side of the computer. Turn this fully clockwise Wait at least 2 seconds Turn it back to fully counterclockwise This will then show the trouble code - (The check engine light will blink to show this, for instance, blink..blink..blink......blink..blink, will be 32) After you read the code, you can start the engine Turn the bolt back to the clockwise position for at least 2 seconds(While running) Turn it back to the counterclockwise position Now shut the car and then start it again, this should of removed the code.

I would also suggest counting the the number of times the red light flashes so you know what code it throuhg. All the codes can be found on http://www.240sx.org faq pages.

The car runs perfect. I don't notice any change at all except for the annoying light. I'm not driving it till I get it to the garage just in case.

if you remove battery it takes a while. I know ive tried it. Ive let my car sit for over 30 min without a battery and it still didn't reset. so i can take my ecu out, and turn little screw alot quicker than i can take out battery. Check the code. might not even have to pay a expensive mechanic to look at it.

Actually if its a california model, leaky fuel injectors will cause the check engine light to come on. The code for that is 45 i believe. I think its different on a DOHC though.

Just got back from the garage. They said the error was the neutral saftey switch. Then they checked it out, and said it doesn't apply to my vehical.

I am able to crank the engine while it's in gear without the clkutch pushed but it has always been like that. I read somewhere they made it like that on purpose for the canadian vehicles.

They reset the error and the light is out now. The error code that it gave which doesn't apply is P0705.

you need the actual switch or the connector?

maybe you could make your 5th or 4th gear connectors to fit into the hole and just splice the wires? since the 5th and 4th gear sensors dont do anything.... except when your traveling at rediculous speeds.... im not sure if it will fit, but you should give it a look!!!!
