NORMAL MAINTENANCE @ 150,000 MILES (240,000 Kilometers) - COOLANT - REPLACE - [Drain, flush, and refill every 150000 miles (240000 Km) or every 60 months, whichever occurs first.]

Not if the car is starting fine and the battery is holding good charge................Hope this helps.

The following URL will take you to an on-line manual for your Accord. Look through the maintainence section on page 219 (especially pages 224 and 225).

You will need Adobe Reader (free from Adobe) to read the manual, and you can not save it except in sections, but you can print off any info you will need.

Hope this helps you.

take it have theme read the codes maybe a vaccum leak,mass air flow sensor,egr valve could be numerous things the code will tell you

you could go to an auto parts store and they can reset it for you, or you could pull your battery cables off the battery and hold them together for about 10 sec. that will clear any codes.

usually comes on when you have to much/to little oil, or it needs to be changed, with the oil filter.. that should be the only reasons for it coming on.

It books for about 3400, so it is not a bad deal, be prepared to replace major parts soon at that mileage no matter how well maintained. I would not purchase it.
