When I turn on my car the maintenance required light on my 2000 Honday Odyssey stays blinking for another 5 seconds once the car is on. Is there a problem

this hard 1 for a diy.check all wires and sensors at wheel hubs for debris,wires yanked from sensors,ect.try reset computer check for codes.

Have u checked the dash for a manual reset button

• 1

  Sit inside the driver's seat of the Honda Accord and close the driver's side door. Any interior lights on can prevent the maintenance required light from resetting properly on some year models.
  

• 2

  Insert the key in the ignition.
  

• 3

  Depress the odometer/trip button located beneath the odometer on the instrument panel. Hold the button down.
  

• 4

  Turn the ignition key two clicks forward to the accessory power position. This is also known as the key-on/engine-off position.
  

• 5

  Continue to hold down the odometer/trip button for up to 15 seconds until the maintenance required light goes out. On some Accord models, the maintenance required light may blink once before going out.
  

• 6

  Release the odometer/trip button and then turn the ignition key to the off position.
  

• 7

  Start the Honda Accord to ensure the maintenance required light is no longer illuminated on the instrument panel. If it still is, the reset procedure did not take and you'll need to repeat the procedure.
  

The maint req. light is a mileage counter. It will turn on every 7500 miles after it has been turned off because that is the factory recommended oil change interval. To turn off the light: with key off, push and hold the trip odometer reset button in. While still holding in the button, turn the key to on but not start. Continue holding the button in until the maint. req. light goes out. Turn key to off.

Code P1456: Evaporative Emission (EVAP) Control System leakage.
Code P0740: Transmission lock up control system.

the first code can be caused by a loose or non-factory fuel cap or a leak.
The second code indicates the transmission torque converter lock-up solenoid could be faulty.

Clear the codes and drive normally for several days. See if the Check Engine light comes on again. If so, have the codes read out and prepare for some repairs. If the light stays off, you had intermittent faults which occur from time to time and nothing is probably wrong.

check all fluids and belts engine running cool forgt the lite pull bulb or put dark tape over it unless you have money to bujrn

The maintenance required light lets you know its time for an oil change. Once the oil is changed the light can be reset. The light will usually blink for a few seconds as you approach the 5,000 mile mark and then stay on steady as the 5,000 mile mark is reached or surpassed.

Most modern cars have what are commonly called Service Lights. Small lights on the instrument panel can now alert drivers when it is time for service.

Most vehicles do this through a computer calculating how many miles have accumulated since the last service.

However, some vehicles use sensors to gather this data. We have compiled a listing on the procedures to reset the reminder lights on your car, if it is equipped.

If you do not see the reset procedure for your vehicle:Reference the owner's manual that came with your vehicle. Reset procedures are often described in depth with illustrations:

turn the key to the accesories position. pump the break pedal 3 times. the check engin light should flash. then turn the key to the off position and then start the car. the light should reset.


I am not sure if that works I have a 2004 Odysey and I did this and it worked.


While the car is off, push and _hold_ in your Trip meter button, then while still holding that button in... turn your ignition key to _On_ (not start). Wait until light goes out or you need a hair cut... which ever comes 1st. LOL, seriously it should go out in about 15 seconds or less

For a 2007 Honda Odyssey: Turn your ignition to the On position. Press and hold down the trip meter button for ~10 seconds (until the display blinks). Release the trip meter button. Press and hold the trip meter button a second time for ~5 seconds (until the display shows your oil at 100%).

Hope helped.

Generally, the maintenance light should come on for a few seconds, then go off after the car has started. All of the dashboard warning lights do this so driver can tell they are operational. (Should see brake light, low oil pressure, airbag warning, etc. Any of the lowly "idiot" lights should come on.)

As a test, turn the key on, but not to start. All of the lights should flash on for a few seconds, sometimes in sequence, then go out. Now, sart the car, some lights may come on and back off. If none stay on after a few seconds of engine running, you are probably ok.

I ran into the same issue. Here's how to fix it.

While the car is off, push in on the odometer reset button and turn on the car.
Continue pushing in the odometer button until the light goes off.
Release the button after the light goes off (usually about 3-5 seconds)

I'm not quite sure on a Toyota, But on a Acura it just meant that by mileage your getting close for your 7500 mile service. then when the light stays on that means your due for the service. also check your owners manuel.
