Probably sensors! I have already replaced the crankshaft positioning sensor once, nissan replaced it once under recall and now it is bad again! Plus my speed sensor is bad too! Go to any part store and get diagnostic test ran, it will tell what sensors are bad.

SOURCE: 2003 Nissan Altima 2.5S, Check Engine Light Problem.

My service engine soon light came on saturday on my 2003 nissan altima 2.5s, took it to the dealer and he stated I need a Catalytic Converter for the light to go off. Last yr Jan I had the same thing happen and there was a recall on the ECM they reset it for free. Any suggestions? I am so tired of getting ripped off being a single woman. The repair price they gave me was $940, my mechanic says he can repair w/new converter total charge of $300

SOURCE: MAINTENANCE REPAIR ON HIGH MILEAGE NISSAN ALTIMA

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. Some problems are minor, but if not addressed it could become major. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. You or a technician will have to perform further testing to pinpoint cause and the proper repair. Even if you reset the light, if the underlying problem is not addressed it will come back on.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

SOURCE: check engine light came on, dealer says its the

Disconnecting the battery might reset the check engine light on some cars. However, instead of doing so, I'd recommend to bring your car to a dealer or a mechanic for proper diagnostic, and here is why:
- not all cars will clear the code after disconnecting the battery
- often, the problem may be actually covered by the warranty and repaired free of charge by your dealer. For example, if you have the code P0420 - Catalyst System Efficiency Below Threshold it's very possible that your catalytic converter is still covered by the original emission warranty and might be replaced free of charge (would cost you close to $1000 otherwise).
- some problems, if not repaired in time may cause a serious damage and more costly repair.
- disconnecting the battery will cause basic settings of the vehicle's computer to be erased (e.g. idle settings, fuel trim settings, transmission shift points, etc.)
- the Readiness code will be erased, which may prevent your car from completing an emissions test. (Readiness code is an indication that certain emission control components of your car have been self-tested)
- the radio, if code-protected, may be locked after disconnecting the battery
- the "check engine" light will come back anyway if the problem still persists.
This can also be related to a coolant flush. Also check that all the car's fluid levels are correct. Thank you, Have a nice day...!

My nissan 2003 altima 2.5s cannot take gas


Could be low fuel pressure or a faulty throttle position sensor.
Have the fuel pressure checked and if the check engine light is on have the computer scanned for trouble codes.

My 2003 nissan altima is taking long to start.


If the check engine light is NOT on, it will be a mechanical problem like a clogged air filter, fuel filter or faulty spark plugs. If your check engine light IS on, it is a sensor like the O2 or MAF for example. Best to get it diagnosed if the check engine is on to specify with sensor is causing the problem.

Pray.
Just kidding. Take it back to the dealership and demand that they find out what the check engine light is for. They may have just put the catalytic converter on wrong.

2003 nissan altima airbag blinking. Engine is running rough. Plus check engine soon light is illiminated.


On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident. Most systems can only be diagnosed using a scanner designed for the airbag system, however some use flash codes to indicate the problem. The scanners at Auto Zone or the ones that sell for @ $50 will not access the airbag system, only the engine systems (check engine light).
This website gives you the procedure for diagnosing and resetting some systems without a scanner. Some vehicle manufacturers accommodate that (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) and some require a scan tool. http://www.airbagsolutions.com/

When i try to start my 2003 2.5 altima i have to


3 to 5 seconds is not really excessive. You might, however, want to try this...depress the gas petal to the floor then turn the ignition while slowly raising you foot off the accelerator. If this helps start the car the check engine light is probably indicating an oxegen sensor problem.

05 altima blows fuse for left headlight


Go out at night, or dusk, with a flash lite, replace the fuse with a higher amp or any spare fuse, turn out the lights, turn on the car lights, look for a spark somewhere, have people standing around engine comp, if it doesn't blow, wiggle wires, if it shorts out, you should see a spark, fix with tape, you should be all set.

2003 Altima shuts off while stopped at red light


If you have a Service Engine Soon light on, then having the computer scanned for codes would be recommended. The code could indicate what the problem may be. The most common is cam and crank sensors.

I would have it checked to verify.

Thanks Jay!

2003 Nissan Altima 2.5S, Check Engine Light Problem.


this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.
