2000 nissan sentra flashing seatbelt light

The fasten seatbelt light in my Sentra sometimes flashes at random. By random, I mean it sometimes does it for a couple minutes or a couple seconds, and it might do it when I start driving or when I've been going for a while. It seems like it starts more often when I get on the highway, but still, doesn't happen everytime.

    I've got the same issue. If my seat belt is fastened, then the seat belt light on the dash will blink constantly. if my seat belt is unfastened, then the light on the dash will stay on for a while, blink, then stay on for a while, blink, etc.

    The Googles have indicated there's a connector under the driver seat. If you push the seat all the way forward you may be able to access it from the back. Push connectors together, unplug/re-plug, and if that doesn't work, unplug and the light will never come on again. Have this issue, haven't tried this solution myself but will when it's light out.

SOURCE: Shaking and service engine light

This sounds like it could be one of several things. What have you done as far as your last tune up? A bad spark plug or wire could do this and it is a simple fix for the shaking. The major problem could be your Timing. The Timing might be off. Your timing and your spark plugs have a lot to do with each other. You mention this happens when you put it in drive. Then you mention shifting gears. Most Nissan's are stick shift. Is your car a stick or manual transmission? When was the last time that you checked or changed your transmission fluid?

On an automatic Transmission.
You have to check your transmission fluid with the car running. You should change your transmission fluid and filter around every 10,000 miles, but nobody ever does this. You need to get some Lucas for transmissions to go in it and it will help a lot if it is jerking. Parts stores know what this is.

This could also be a sensor going bad. If you have a parts store in your area, you can take it to them to run a diagnostic on it. If you take it to a garage, it could cast anywhere from $100 to $200 for them to do the same test. Autozone in my area does this test for free. Some other parts stores do them, but I do not know about your area. The big problem with the sensors is that the test might not tell you the exact sensor that is bad. The best thing to do is to have the parts store run the free test for you. Then if it is the plugs and or wires, buy a set of NGK plugs for your car and a lifetime set of wires. (Bad plugs and wires can show up as a sensor sometimes.) Then you will need to reset the service engine light, so you will know if the problem is fixed. To do this you can sometimes unhook your battery for a few minutes to reset the computer. If that does not reset the engine computer, the parts store that did the test can reset it for you. Try the cheapest thing first which is the plugs and wires. Also change your transmission fluid and filter. If you have not changed your oil in the last 3,000 mile you need to change your oil and use Lucas oil additive along with Castrol motor oil. If you live in a climate where it does not get over 80 degrees you can use 10w40. If it gets over 80 degrees you need to use 20w50. (Some places and people are using 5w30, but this is mainly for brand new cars without any leaks or burning oil.) The Lucas will protect your engine and make it run smooth. Lucas is great stuff for any engine new or old. It is cheaper to buy it by the Gallon, if you are going to use it a lot. It is the best thing for an old engine. You can use up to 2 quarts of it in an engine and I have heard of people using more than that.

Ask me more questions if you need to. That is what I am here for. Do not rate this right away unless you are satisfied.
If this solves your problem rate it as a Fixya not a helpful or thanks for trying.

Find the big hose that comes out of the top of the radiator and follow it to the engine and that is where the thermostat is located. My advice is to be sure to get a factory thermostat and rubber gasket as it makes installation much easier. I have done it both ways and the factory one is easier to install.

Its possible, that you crank angle sensor is failing. Also, that vehicle had a issue with the ECM/computer. Nissan put a set of foams inside of the ECM box to prevent the ECM from movement, however the glue that they used to attach the foams was causing the ECM to fail. The vapors from the glue would eat up vital circuits inside the computer causing failuer. I would go to your local dealer and provide them with your VIN nujber. With the VIN number, thay can check to ysee if the foam campaign has been doen and also the crank and cam angle sensor camaign. Nissan volunteraly replaced cam and crank angle sensors if the VIN number matches the campaign. Your ECM/computer is covered for 8years or 80000 miles. We are also starting to see timing chains getting stretched causing running issues, but you will have a "check engine light on" for cam angle sensor circuit. Anyhow, go to your local friendly NIssan dealer and have them run your VIN number to see if you have any open campaigns (crank and cam sensors, ECM foam etc.) Good luck and let me know what you find.

Dexron-III is what's used in almost all vehicles (except some older fords and chryslers), but you can check the owners' manual to be sure (or call the nearest Nissan dealership).

1999 Nissan Sentra 1.6L sets p0304 code


check that your spark plug wires are all secured tight. the far right cylinder is giving you the issue, cylinder #4. Is the engine light flashing while the car is running? if it isnt flashing, then its a past code and isnt misfiring anymore. if the engine light is flashing, you either have a bad plug wire, or a bad ignition coil/distributor.

2000 nissan sentra manual transmission 1st and 2nd gear misfiring....


Sounds like you have a major misfire problem. The light is flashing because the ecm has determined that the problem is severe enough to cause damage to something. If your engine light flashes it is a warning not to drive the vehicle. I'm assuming this is a four cylinder. My guess would be that only two of the cylinders are actually producing any power. I would need the following details to help you further. How many miles are on this engine? Has the necessary factory maintenance schedule been maintained? In other words have the appropriate parts been changed and serviced to keep this engine performing properly. Many things could be causing your issues. Do the necessary maintenance first, like spark plugs and whatever the manufacturer requires and see what happens. If this does not help I can help you with the rest.

I have a Nissan Sentra XE 2000 Ocasionally gets an overdrive light, the car boggs down, and won't move. When the light goes out it will run ok. but it comes and goes intermittently. More now than then....


start with scanning your system with CONSULT2. unfortunatelly this tool is only available at your friendly nissan dealer. generic scanners are not capable of retreiving codes from trans modules/components unless you have a more expensive scanner such as SNAP ON SOLUS or something similar. small scanner for $50 bucks from auto parts store usually doesnt read trans codes. engine codes only. if your O/D loght is flashing that means transmission issue. could be the solenoid pack on the valve body other elecrical component or convertor failure. have it scanned for codes first. then let mr know ehat the number is for the code.

Need to know 04 nissan sentra spec v valve flash sequence to fix tapping sound in engine


Not sure what you mean about a flash sequence. If there is a tapping noise,check your oil level and quality. When oil is low, the valve timing solenoid can not function properly as it runs on oil pressure. This will cause your tick noise. If your engine is burning oil the catalyst may be at fault. They break up and enter the engine through the exhaust valve and damage the cylinder.
