"Service engine soon" light

sonic370 · 01-29-2011, 07:40 PM

it's the gas cap. same thing here. took two trips to the dealer and two different gas caps and finally it cleared up. this is a known problem

Baddriver · 02-24-2011, 03:40 AM

Hey guys. So we're still back to the gas cap?

I thought it was a part (valve) replacement. Final verdict?

This is annoying. I have a code reader/eraser in my car because of this.

(I exported my usdm nismo so can't bring it in for warranty)

I had the Service Engine Soon light. Called dealer. They waited two days to see if it clears. It doesn't. I made an appointment today, and they replaced the fuel cap. Possibly design malfunction on the 2009-2010

Apparently it's a known issue to Nissan.

Its a known issue i had mine replaced 3 !!!! times before it helped.
If it comes back on have them replace the fuel filler neck also.

Well, I'll join the club of the iluminated light. Not at all impressed to see this many reports of a known issue and the dealer service departments still knowing relatively little about it.

Shame on Nissan.

It's a known issue. Just keep bugging them about it.
They even had to pressure my system and blow smoke in
It to search for small evac leaks

I have the same code but it is because I broke a connector in my carbon evap canister and had a loose tube... I hope to fix it by gluing back the connector because my car is not under warranty

If not I must have to buy a new one ($350), that damn thing is a black plastic box hidden behind the passenger side rear wheel, with tubes coming out of it. Connectors seemed to be rather weak.

Just got F.I. rest. Test Pipes + TDX CBE installed. After 300 miles my SES lit up, how do i know if it is the test pipes leak causing it? and if so what can do about it? I was under the impression that one shouldn't throw an SES light with the test pipes because the 02 sensor still connect to them. any advice will help thanks.

I have GTM resonated test pipes and don't seem to have any issues. The CEL has only come on once after filling up. I just turned the gas cap several clicks and the light went off after a few days. It hasn't come on again since.

I'd pull the code and go from there. Procedure is a few pages back.

1. Confirm that accelerator pedal is fully released, turn ignition switch ON (DO NOT depress clutch while you're doing this) and wait 3 seconds.

Repeat #2 procedure quickly five times within 5 seconds:
2. Fully depress then release the accelerator pedal.

3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.

4. Fully release the accelerator pedal (while the CEL is still blinking)

5. Wait about 10 seconds.

6. Fully depress the accelerator pedal and keep it down for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).

Turn ignition switch to OFF position

Turn ignition switch to ON position and now you can start the car. The CEL light should be gone.

Rep me if this works for you as it did for me.

Ok, I just installed HFCs and cat back exhaust. I did disconnect the negative battery terminal because the directions stated to. Now I have a Service Engine Soon light when the car is running.
I tried the above meathod to clear the SES light with no luck. Will removing the negative battery terminal for a minute or two clear the code like the gas pedal meathod? If so, how long should I keep the negative terminal disconnected for before I reconnect it?
Thanks!

Had the same issue with my 09 370Z...Pulled the MAF sensors off and cleaned them with MAF cleaner and replaced air filters on both sides. Did a reset on the warning light and haven't seen it since

thanks for the heads up!
