Good morning every body,

I have 350z 2004. The story of the problem was I take the car to car washing service. After finishing the body wash I drive the car for 1KM and after that I saw the engine light on dash. I check the manual which request the dealer visit. I take car there after checking the car they told my, that it is due to the servicing (the car need to be service). I take appointment which was after 1 week and take car for them before I reach the dealer service location the light disappeared. I do the service (80,000KM) and every think is ok until 7days pack, the weather was cloudy and it starts raining. I drive my car for 100KM not all the way was wetted. The check engine appear again and still appeared.
What is the problem?
I can't wash the car or drive it on the wet way or there is place where the water comes inside the car and contacts some wires.
Or the problem from the engine side

For the information I drive and it is normal accelerating performance every think is fine.

 

i have no idea but my check engine light won't go off either, and i've already had my check up ...

 

yup i took mine to the dealer and it was serviced and the light doesnt go off. I dont know why it does that im gonna have to go back. btw mine is an 05

 

Random.

You guys need to have the codes checked. This thread is super vague.

 

Mines off and on too... kind of like the weather here in Chicago. Its bizzare!

I'm going to have the guys plug-in and see whats up... hopefully its nothing.
I have an 04.

cars with CEL on will not pass california smog inspection.

 

My first Z did that!I had a small pin hole in a rubber hose that was behind my driver side seat.It was part of the fuel line or something like I had the hose replaced they cleared the codes on the computer and the light never came on agin.That light can also come on if your gas cap is not on tight.

 

I did some checking around for you guys and on the 03 04 350z they had a problem with the fuel vapor hoses cracking and also the fuel filler hose doing the same thing that is why the check engine light is on. That was the problem I had with my first Z.

 

Good morning guys
After I take my car to the dealer and do inspection.
The problem was from O2 sensor in the Y-pipe in the exhaust. While I replace my Y pipe with costume one and the connection and the sensor leave with out blocking, so while driving in the water the water goes into the sensor wire and make short circuit and check engine appear.
Thank you all for replaying me and sharing you info.
