Maintence light my honda accord is a 92 and has 230,000 miles, runs great. My maintence required light is on, but it doesnt run any different. Should i be concerned??

sounds more likely to be a warn sensor could be cam or crank sensor, its not being able to read engine speed to adjust time.

Yes they do have a service interval at 75k I'm guessing your check engine light may have just popped on and you can't figure out why??? Have it checked for trouble codes and let me know what you come up with. Check service manual for maintenance requirements if you're a do it yourselfer. Let me know if you have any codes or any other questions

depend on many conditions how well has the motor be maintained how it runs now and how it is driven

For a 2003 used Honda odyssey, the following should be required:-

1. Replace the timing belt. (repair estimates at www.repairpal.com)
2. Drain the whole oil out of the engine and transmission
3. Replace the brake pads
4. Most of all run a diagnosis scan on the vehicle to detect any other possible maintenance that will be required.

Good luck and a good buy.

Take care.

Maintenance Required is a light that comes on after a predetermined number of miles. For example, if the maintenance schedule Honda set for the car calls for an oil change at 3000 miles, a new fan belt at 6000 miles, and another oil change at 9000 miles, then the maintenance required light will come on every 3000 miles and stay on until it is reset by the dealer. Some people, especially those that do their own regular maintenance but don't have a way to reset the light themselves, find this an annoyance. But others find it useful and take their cars in to the dealer every time the light comes on, and they rest assured that all of the regular maintenance is always done on time.

What this light does NOT do however is signal that there is anything immanently wrong with your car. It is not a "Check Engine" light (that's the one you should worry about if it ever comes on), but merely a reminder for you to do preventative maintenance. That doesn't mean you should *ignore* it, per se, as you want to make sure you have your car on some kind of maintenance schedule, even if yours is not as strict as Honda's. But there is no need to panic.

Look at the owners manual it will tell you how to turn it off. But before you do that check your milage with the maintance interval list located in the owners manual. The maintance light goes on when a certain milage is obtained which will describe the type of maintence is required.

It will; always do that on some vehicles, as long as it doesnt stay on for an extended period of time, i wouldnt worry about it so much.

Simple way to check if anything goes wrong is to go to Autozone store (if you are in US) and scan for trouble codes (if there are any of them). They do it free of charge. If you get any codes you can get the explanation of them here

turn the key off, then hold the odometer reset button in, turn key on and keep holding, the light will flash off then on once, keep holding until light stays out, start car and all should be ok
