Your “check engine” light come on as soon as your car’s onboard computer (or PCM, Powertrain manage Module) documents some kind of problem. This onboard computer runs your car so the it has optimum fuel economy and low emissions. The PCM create a code indicating what part or mechanism is malfunctioning (electrical system, oxygen sensors, and also so on). Your tech can get the password from the vehicle and also look up its meaning.

In the meantime, you’re most likely wondering: what are the possibilities? Is over there something walk on in your car or in her life that motivated this “check engine” situation? Where should a mechanic start looking to find the problem?

How Long deserve to You Drive with Your inspect Engine irradiate On?

Is the vehicle running normally? If your vehicle is to run normally, and also you have no trouble driving it, the problem is not so major that you should panic. That course, you have to not disregard the light; that is warning you of some difficulty with the emissions system. As soon as the irradiate is on, your car runs top top default parameters, not optimized to reduce emissions and increase mileage, and so girlfriend won’t gain the gas purpose of use the vehicle is designed to get. Just contact your mechanic or dealer to make an meeting within a reasonable amount of time.Is the "check engine" light flashing? If it's flashing, it method you have a serious problem and also you really should not it is in driving her car. It's flashing due to the fact that it's speak “STOP!!! Hey, Look in ~ Me!!!” It’s saying your catalytic converter is being damaged. It’s probably a great idea to speak to a tow truck at this point; you don’t want to add to the expense of any kind of repairs that will certainly be needed.

What walk the check Engine light Mean?

The examine engine irradiate is a light that the engine computer system uses to signify that over there is something wrong. They are orange, amber, or yellow, and not to it is in ignored!

How come Reset the examine Engine Light

The only method to "reset" the check engine irradiate is by resolving the difficulty causing it. Thus, the 10 reasons I list listed below may aid you reset your inspect engine light.

Why Is My check Engine irradiate on? 10 factors Why Your examine Engine light On

1. Has actually Your car Been Serviced Recently?

If your vehicle has been in the shop recently for service, it’s quite possible the technician has actually caused her "check engine" light problem. Occasionally a technician will forget to reinstall a connector come a sensor, or not snap the connector back together completely. Or that or she might knock a connector loose while law a boy service.

On older Hondas, the oxygen sensor is directly below the oil filter, so a technician removed the oil filter because that a regimen oil adjust might spill oil top top the oxygen sensor. It’s just possible, though not common, the a technician wiping oil turn off the sensor damaged that somehow.


On this 1991 Honda Accord, you have the right to see how the oxygen sensor (little rat-tailed item) is located directly listed below the oil filter. You have the right to imagine exactly how easy that is come dump oil top top it.


2. Have You fueled Your auto Recently?

If you didn’t tighten the fuel cap sufficient (or forgot to put it on altogether!), the can cause your "check engine" light to come on. Every Honda fuel caps have actually a ratcheting an equipment built into the cap to accomplish a an excellent seal and keep you from over-tightening the cap. When tightening her fuel cap, be sure to rotate it sufficient to hear at the very least three clicks; that ensures the ideal torque to be applied. If your check engine light is on, simply examine your fuel cap to make certain it is turned three clicks.

3. Did friend Overfill her Fuel Tank?

If you’re one of those people who prefer to optimal off the fuel tank, you have to break the habit, specifically if you own a newer Honda. When the gas pump shuts turn off automatically, the tank is as full as it needs to be. To keep gasoline fumes the end of the atmosphere, modern United claims cars are required to trap the fumes and also recycle them into the engine to be burned. Overfilling the tank can spill fuel into tiny vacuum lines and filters, which in turn have the right to clog emission devices (like the "evap canister" being replaced in the three do-it-yourself videos in ~ the end of this article). Soaking these devices in petrol will cause the "check engine" light to come on. Replacing the damaged parts can be costly, but the time spent diagnosing the problem might be even an ext so.

4. Have You installed Any new Electronic gadgets Lately, or had actually Them set up by a Professional?

Everyone likes all the new gadgets available for cars these days, like back-up cameras, thunder-booming stereos, remote auto starters, high-intensity-discharge headlights, and rear entertainment systems, to surname a few. It’s just possible that the human being installing your machine may have blown a fuse, or worse, may have actually tapped into the wrong wire and caused the dang "check engine" light to which again.

Check to watch that all electronic devices in the vehicle are working correctly (e.g. Dash light, 12-volt strength supply, internal lights). If whatever is functioning properly, I would either test every the fuses (using a test light or a voltage meter is the fastest method to carry out that) or return the auto to the human who walk the work.

5. Did your "Check Engine" irradiate Come on ~ Driving through a Deep Puddle?

This isn’t common however it does happen. ~ driving because that a if on the highway, her exhaust deserve to get exceptionally hot; if you then take place to drive through a deep puddle, it is feasible for water come cool the oxygen sensor also quickly and also crack the product inside the sensor. The oxygen sensor is situated under the vehicle, typically in or close to the catalytic converter where the temperature can exceed 600 degrees. If this sounds like your scenario, take it your automobile to the dealer or your local mechanic.


You deserve to see both oxygen sensors, front and rear, one in the front pipe prior to the catalytic converter and the other is in the center of the catalytic converter. If you hit a pond deep enough, you could actually submerge the sensors.


6. Perform You Have too much Humidity in Your vehicle Caused by a Water Leak?

Water top top the former or back carpet in your vehicle will often be coming from the former of the vehicle somewhere; water flows towards the back because of acceleration, and because the floor is tapered in the direction of the rear of the vehicle. If the water is only visible top top the rear carpet, the leak might be in the behind of the vehicle.

The many common cause of a water leak is the windshield; sometimes a freshly replaced windshield will certainly leak.

If a leaky windshield drips water on an ECU (Engine manage Unit) fuse crate or any other control unit, this will reason an ECU failure and also your “check engine” light will certainly come on. Water is very damaging to all electronic tools (just drop your smartphone in water and also see what happens).

7. Carry out You Live in a countryside Area where There Are several Critters?

Critters can reason all sorts of difficulties in cars, from awful smells to chewed wires. If girlfriend live or work-related in one area where mice, rats, chipmunks. Or squirrels can gain into your car, they can wreak destruction on your cars’ electric systems. Given the chance, critters will develop nests and store food because that the winter, and also for part reason, they choose to chew wires. In fact, some auto manufacturers assemble cable harnesses wrapped with mouse-deterrent tape, no kidding. It’s not fully effective yet it’s a start. If a critter chews the best wires in your vehicle, it will cause the “check engine” irradiate to come on, and an expensive bill! replacing a cable harness is challenging and time-consuming.

Signs the critters in your vehicle are:

bad odorsacorns and nuts (or dry dog food) stored in the engine compartment or glove boxchewed carpetingloud noises once the heater or wait conditioning pan come on. Critters are notorious for structure nests inside blower motor assemblies, leading to all type of problems.

8. Are various other Warning lamp Illuminated on the Dash?

In some cases, a failure in another part or device can cause your "check engine" light to come on. Multiple warning lamp illuminated on the dash don't necessarily typical multiple problems, for this reason don't panic. The lights might all be brought about by a solitary problem: because that example, if your alternator is not charging, or if it’s over-charging, that could reason low or high voltage in the system, which would reason many lights to come on.

9. Walk Your car Sit because that a lengthy Time there is no Anyone control It?

Cars the sit because that a long period of time room susceptible come a plethora of problems. Critters move in, batteries go dead, tires go flat, brake rotors come to be rusted and cause a pulsation when applying the brakes, pulleys rust and also cause belts come squeak, and the perform goes on. If your vehicle sat for a while, your "check engine" light might come on since a sensor or solenoid is stuck, or for various other reasons. Have it checked out by an moral mechanic; they room out there, friend just have actually to discover them.

10. To be You the critical One come Drive your Car?

If girlfriend were not the critical one to drive her car and also the "check engine" irradiate is on, you need to start questioning questions. Sometimes family members members or friends that borrow your auto spill soda or coffee on the console without telling you. On some Hondas, the ECM/PCM (engine control unit/powertrain manage unit) is located below the facility of the console, and sugary drink can destroy this expensive manage unit.

Automatic Scan Tool: write Down the Code

If you have a buddy, friend, uncle, or cuz the can examine the code since they have actually a scan tool, make sure you create down the code since if you decide to erase it, you’ll want to understand what that was as soon as the irradiate comes earlier on (and if it’s an worry other than a loosened gas cap, the problem will usually come back). It’s good practice for you and great information to give your mechanic.

Buying a Scan device to analyze "Check Engine" Codes

If you desire to shot and diagnose the difficulty yourself, friend will need to figure out with the diagnostic password is telling you. Right here is a overview to expertise the codes.

You will also need a scan tool. If you decision to purchase on, select one that will last because that years. Vehicles are only getting much more sophisticated every year, so setup for the future. The OBD2 mechanism covers 1996 and also later car (the OBD1 mechanism that covers older ones might be included, relying on the device). Ns recommend looking for these 4 time- and also money-saving features:

A display that contains a description of the reason of the warning light, as well as the code. This saves you time from having to look increase the description that goes with the numerical password in a book or ~ above the computer.LED display screen for state emissions readiness check and also drive bicycle verification. This function will permit you know if it will certainly pass one emissions test.Battery backup that will keep the password in the maker after you disconnect the scan tool, therefore you can review it and also analyze it far from the auto (even if you forgot to create down the code)A USB cable to update the details in her scan device from your very own computer. If friend can't update the scan tool, it will certainly be obsolete in three years.
