Turn the key to activate the power but not start the ignition, do this a handfull of times. The check engine light should blink a specific number of times, this can be referenced to identify the problem, after this happens the light should turn off until you have another problem!There's a difference between the "check engine" light and the "engine maintenance required" light (aka "Emission Maintenance Reminder" or EMR light). The EMR light is strickly a reminder that emission system maintenance is due. This includes the EGR valve, PCV valve, & Oxygen sensor. It is program to light at approximately 60,000, 82,500, & 120,000 miles. Because its activated by mileage, it does not necessarily mean that something has malfuction. Unfortunately, the only way to reset it is by using a diagnostic scan tool. Of course, you could always remove the bulb.

Maintanence required is blinking when starts

Sounds like your car needs a tune up. At a certain mileage the car probably needs an oil change and other maitanence. Go on YouTube and watch a video to reset the button. Good luck.

Maintanence required light

A maintenance required light means some type of maintenance is required on your car. It wont clear until the maintenance is done. Unfortunately you will probably have take it to a dealer for repair and clearing the code.

Maintanence required light stays on 61200 miles on vehicle. How do I shut it off? Not due an oil change at this time.

the sensor for that goes by the consistency of the oil and how its been driven, not by mileage. Change the oil!!

The maintanence light is on how do i reset it

The Emission Maintenance Reminder System (EMR) is incorporated into the engine Powertrain Control Module (PCM). On 1989 to 1995 models, the Chrysler Diagnosis Read-Out Box 2 (DBR2) is required to reset the EMR. clay58_49.png

2005 honda ex maintanence required light went on

It's a reminder that it's time to do your maintanence(oil change, tire rotation, replace air fliter, etc..your service book will tell you what service your need to do base on the mileage). A lot of the time people just get a oil change and reset the light. The light can be reset at anytime.

With the headlight OFF push and hold the trip/reset button or stick (located in front of the gauge below the MPH speedo) , turn the ignition switch ON (II), and continue to hold the button for more than 40 seconds. If you did it right the light should go out.

good luck

Maintanance required light on

Generally this its one warning to the time mantenance is END, and need change fluids and other components. If the CHECK ENGINE turn on, need scanned the PCM to know any fault code there.

Hope helps.

Hello, I have a 2002 honda civic ex. When I turn the key on I get the maintanence required light. after the engine starts the light blinks 10 times and then goes out. I couldn't find any guidance in the...

First, make sure you are talking about your mainanence required light, and not your check engine light.
Your maintanence required light is telling you that some normal maintanence is required since you have traveled some pre-determined number of miles (pre-determined by Honda). For example, it could mean an oil change should take place, etc. If you keep track of those things on your own, then you need only reset the light, as follows:
Turn off the engine.
Press and hold the Select/Reset knob (odometer) in the instrument panel, then turn the ignition switch just to ON (II). Do not start the car.
Hold the knob for approximately ten seconds until the indicator resets.
Hope this helps you.

Engine light on dash stays on.

There are two lights you may be getting confused. There is the check engine light and the maintanence required light. The maint req. light can be manually reset by holding down the trip meter button then turning your ignition key forward. You have to hold the button down until the light goes away.
If it is the check engine light you should run a daignostic check for the listed codes.
