Service Engine Soon Light
 
Hi, the Service Engine Soon light came on in my 2003 Altima 2.5SL. I checked the fuel cap as it said in the owner's manual and it appears to be fine.

I was wondering if it happens to be too much water in the gas tank due to bad gas and I use a water replacer additive would the light go out if the problem corrects itself or do I have to get it reset by a Nissan Technician even if the problem is corrected?

Thanks

You need to find out first what is the code. Go to your nearst auto parts store and have them check the codes for you, they usualy do it for free. With the code you can find out exactly what the problem is.

Hi, thanks for the info. I went to the dealer and the codes they pulled was P0335 crank sensor and P0725 eng speed signal.

The dealer changed the crank sensor and everything was working fine for a day but the engine service light came on again.

The car seems to be working fine since they changed the crank sensor and then about 5 days later the service engine went out. I called the dealer and they said it might be another code coming up now but if it is the crank sensor they will warranty the part. Hopefully it stays out since I had to pay for the crank sensor and they will probably charge me to dump the codes again :):censored:

I saw another thread with some people having the same issues. Is this common?

Yes, the crank sensor problem is common. There is recall for some 2003 altima, you should check if your altima fall in the VIN range. Here is the recall: VOLUNTARY RECALL CAMPAIGN 2003 NISSAN ALTIMA AND SENTRA WITH QR25DE ENGINE CRANK ANGLE SENSOR / ECM REPROGRAMMING

Hi, my vehicle does fall in that range. I had the ecm re-programmed back in Oct 2006. So it appears in that bulletin I'm not eligible for a refund since I had the crank sensor replaced after the ecm was re-programmed. Would I have any type of argument? I'm surprised my dealer didn't bring this up. It appears to me it's a fault on Nissan's end but proving it would be tough probably. Thanks for the info.
