Service Engine Soon Light came on

I have a 2003 SL with 45k on it.

Light came on last night.
i'm fearing the worst (CVT related). The car hasn't shown any signs of CVT problems though.

Gas cap seems fine.

I'm taking it to the dealer in two days.

Since I bought it in March of '03, I guess I'm out of luck and it won't be covered in case problems are found?

thanks.

Before jumping to conclusion, find out what the error code is. Auto Zone and most other part stores will read the code for you free of charge.

Even if it is the CVT, with only 45k miles on it and only two months past the 5 year powertrain warranty period, Nissan may still cover it under their "good will" policy.

My light came on last week. I have a 2004 with 55,000 miles on it.
It turned out to be the fuel filler line (?) had a leak in it. It was leaking vapors and that's what set the light to go off.
It cost $527.00 to replace it.....ouch.

Sounds like a plan!
Will stop buy Auto Zone later on today.

Now, what will this code tell me? Will that have the answer as to why the light is on?

thanks.

The code(s) will list the problem(s) that caused the light to come on. They will enable you to determine if the root cause is a minor or major problem.

Post the code here and someone can help with the diagnosis.

Good luck.

Here it comes!
Just came back from AutoZone.

code: P0305

Definition:

Cylinder misfire detected - Cylinder number 5

Explanation:

The powertrain control module monitors the crankshaft speed and has detected a misfire condition.

Probable Causes:

1. Ignition system fault - spark plugs, ignition wires, coil.
2. Vacuum leak.
3. Injector fault.
4. High or low fuel pressure.


None of this stuff means anything to me. Can someone please clarify?

I'm scheduled to go to the dealer on Thursday.

What should I do?

ny941932-

Did the light ever blink or was it always steady? With the P0301 thru P0306 error codes the light will blink if the misfiring condition is likely to damage the catalytic converters. If the light is steady then the problem is a one-time or intermittent event.

The probable causes are listed in the attached chart. My guess would be a defective air/fuel sensor or an air leak in the intake system.

Since your car is out of warranty it might be cheaper to take it to a reputable mechanic instead of a Nissan dealer.

No, the light never blinked, just came on steady yesterday.

I will see a mechanic tomorrow.

I will report the results afterwards.


Thanks very much!

This morning the light was on again, however, when I got to the mechanic it was off.

Ok, so he plugged in the code reader, same code came up (P0305).

He checked the A/F filter readings on his computer, everything looked fine.

Since the light is off now. He thinks it had to do with heavy rains/moisture over the last few days. Supposedly it could've caused a one time cylinder misfire.

Therefore, we left it at that.

If the light comes back, we'll revisit the issue.


Does this sound satisfactory?

Yes, it does.

According to the Service Manual, if the misfiring condition is no longer present the Check-Engine light will go out. It may have been an isolated, one-time event.

If the problem is intermittent the light may come back on. With this particular error code, you only have to be concerned if the light is flashing, which indicates the misfiring condition may be severe enough to damage the expensive catalytic converters.

I would trust your mechanic and not worry about it.

hello murano lovers!
(i'm quite new to this actually...first post ever)

my family murano was purchased this past Feb (brand new 07 SL AWD). so far, no issues....up until this point.

i've experienced the same thing with the 'service engine soon' light coming on. i checked the cap to see if it was tightly on and it was on tightly.

however, i'm not sure if this could've contributed to the problem:
-the car was on a full tank of gas
-the weather was in the 30's (humidity, feels like 40 something)
-the car is always on a full tank of gas (even if it's half full, my dad insists on filling it up to the max)
-the car is only driven approx 2 times a week (so for most of the week, the MO is parked in the garage....with a full tank of gas!)

i was told if the weather is too hot or humid and if you're driving the car itself, the tank will actually expand a bit.

my best guess is that if indeed this did occur, it could've set off the sensor in the gas cap area, but i'm not quite sure. i'm not sure if anyone else has experienced this issue with the full tank of gas and humid weather.

this occurred 2-3 days ago. the light warning light remained steady until sometime in the afternoon today, when we killed off some gas by driving it more often this weekend. the light finally went away.

The EC section of the service manual (page EC-64 in my 2004 manual) explains how to set the diagnostic test mode to get the Service Engine code(s), and then how to erase the code(s) - all by simply using the accelerator pedal.

I did this procedure on my 04 SE several years ago when the Service engine light came on, and got a throttle sensor code P2135. I reset the code (figuring the first time it came on it just might be a fluke), and the car has been perfect ever since. The code never came back and (naturally) the Service engine light hasn't returned either.

I've had fluky, mysterious codes once in a while on my 95 Maxima - now with 195K miles. Just reset the codes (as long as the engine is still running OK, of course) and if they keep coming back, then investigate further.
