You are watching: 1997 honda civic check engine light


Your “check engine” light comes on once your car’s onboard computer system (or PCM, Powertrain control Module) documents some sort of problem. This onboard computer system runs your automobile so the it has optimum fuel economy and also low emissions. The PCM creates a code indicating what part or device is malfunctioning (electrical system, oxygen sensors, and also so on). Your tech can get the code from the vehicle and also look up its meaning.

In the meantime, you’re more than likely wondering: what room the possibilities? Is over there something walk on in your vehicle or in her life that prompted this “check engine” situation? Where must a mechanic begin looking to find the problem?

The first Two concerns to Ask you yourself if the examine Engine irradiate Is On

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

Is the auto running normally? If your automobile is to run normally, and you have no difficulty driving it, the trouble is not so severe that you must panic. That course, you must not ignore the light; that is warning friend of some problem with the emissions system. When the irradiate is on, your car runs ~ above default parameters, no optimized to minimize emissions and increase mileage, and so girlfriend won’t acquire the gas purpose of use the car is designed come get. Just contact your mechanic or dealer to do an appointment within a reasonable lot of time.Is the "check engine" irradiate flashing? If it's flashing, it way you have a severe problem and also you really need to not it is in driving your car. It's flashing because it's saying “STOP!!! Hey, Look at Me!!!” It’s saying your catalytic converter is gift damaged. It’s more than likely a an excellent idea to contact a tow van at this point; you don’t desire to include to the price of any kind of repairs that will be needed.

What go the check Engine light Mean?

The check engine irradiate is a light that the engine computer uses to denote that there is other wrong. They space orange, amber, or yellow, and not to it is in ignored!

How come Reset the check Engine Light

The only method to "reset" the check engine light is by addressing the trouble causing it. Thus, the 10 factors I list below may help you reset your inspect engine light.

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

1. Has Your auto Been Serviced Recently?

If your automobile has been in the shop recently for service, it’s quite possible the technician has caused your "check engine" light problem. Sometimes a technician will certainly forget come reinstall a connector come a sensor, or no snap the connector earlier together completely. Or the or she may knock a connector loose while act a young service.

On larger Hondas, the oxygen sensor is directly below the oil filter, for this reason a technician removing the oil filter for a regime oil adjust might pour out oil ~ above the oxygen sensor. It’s just possible, though no common, that a technician clean everything oil turn off the sensor damaged that somehow.


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


2. Have actually You sustained Your auto Recently?

If friend didn’t tighten the fuel cap enough (or forgot to put it on altogether!), that can reason your "check engine" light to come on. All Honda fuel caps have actually a ratcheting an equipment built into the lid to achieve a good seal and keep girlfriend from over-tightening the cap. Once tightening her fuel cap, be certain to revolve it enough to listen at the very least three clicks; that ensures the suitable torque was applied. If your inspect engine light is on, simply examine your fuel lid to make sure it is turned 3 clicks.

3. Did you Overfill your Fuel Tank?

If you’re one of those people who prefer to top off the fuel tank, you should break that habit, particularly if you very own a newer Honda. Once the gas pump shuts turn off automatically, the tank is as complete as it needs to be. To save gasoline fumes out of the atmosphere, modern-day United claims cars are required to catch the fumes and recycle them right into the engine to it is in burned. Overfilling the tank have the right to spill fuel into tiny vacuum lines and also filters, which in turn have the right to clog emission tools (like the "evap canister" being replaced in the 3 do-it-yourself videos at the end of this article). Soaking these tools in petrol will reason the "check engine" irradiate to come on. Instead of the damaged parts could be costly, yet the time invested diagnosing the problem could be even more so.

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

Everyone likes all the new gadgets obtainable for cars these days, like backup cameras, thunder-booming stereos, remote automobile starters, high-intensity-discharge headlights, and also rear entertain systems, to surname a few. It’s just possible that the human installing your maker may have actually blown a fuse, or worse, may have tapped right into the dorn wire and caused that dang "check engine" light to come on again.

Check to watch that all electronics in the auto are working appropriately (e.g. Dash light, 12-volt power supply, interior lights). If everything is functioning properly, I would either test every the fuses (using a test light or a voltage meter is the fastest means to carry out that) or return the car to the person who go the work.

5. Did her "Check Engine" light Come on after ~ Driving v a Deep Puddle?

This isn’t common yet it go happen. After driving for a if on the highway, her exhaust have the right to get very hot; if you then take place to drive through a deep puddle, that is feasible for water come cool the oxygen sensor too quickly and also crack the material inside the sensor. The oxygen sensor is situated under the vehicle, commonly in or close to the catalytic converter whereby the temperature can exceed 600 degrees. If this sounds like your scenario, take your car to the dealer or your neighborhood mechanic.


You have the right to see both oxygen sensors, front and also rear, one in the former pipe prior to the catalytic converter and the other is in the facility of the catalytic converter. If you hit a pond deep enough, you can actually submerge the sensors.


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

Water top top the prior or earlier carpet in your auto will regularly be comes from the prior of the car somewhere; water flows in the direction of the earlier because that acceleration, and because the floor is tapered in the direction of the behind of the vehicle. If the water is just visible on the behind carpet, the leak might be in the behind of the vehicle.

The most common cause of a water leak is the windshield; occasionally a recently replaced windshield will certainly leak.

If a leaky windshield drips water on one ECU (Engine control Unit) fuse crate or any type of other regulate unit, this will cause an ECU failure and your “check engine” light will come on. Water is really damaging to all electronic gadgets (just drop your smartphone in water and see what happens).

7. Carry out You Live in a rural Area whereby There Are numerous Critters?

Critters can reason all kinds of problems in cars, from dreadful smells come chewed wires. If friend live or job-related in an area whereby mice, rats, chipmunks. Or squirrels can get into your car, they have the right to wreak destruction on your cars’ electric systems. Provided the chance, critters will construct nests and store food for the winter, and for part reason, they choose to chew wires. In fact, some automobile manufacturers assemble wire harnesses wrapped with mouse-deterrent tape, no kidding. It’s not fully effective however it’s a start. If a critter chews the right wires in her vehicle, it will cause the “check engine” light to come on, and also an high-quality bill! instead of a cable harness is an overwhelming and time-consuming.

Signs that critters in your auto are:

bad odorsacorns and nuts (or dry dog food) stored in the engine compartment or gloves boxchewed carpetingloud noises once the heating or air conditioning pan come on. Critters are infamous for structure nests inside blower motor assemblies, causing all kinds of problems.

8. Are other Warning lights Illuminated top top the Dash?

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

9. Go Your car Sit for a lengthy Time without Anyone steering It?

Cars that sit because that a long duration of time space susceptible come a plethora of problems. Critters relocate in, batteries go dead, tires walk flat, brake rotors come to be rusted and cause a pulsation when using the brakes, pulleys rust and also cause belts to squeak, and the list goes on. If your car sat because that a while, your "check engine" light might come on since a sensor or solenoid is stuck, or for other reasons. Have it viewed by an honest mechanic; they room out there, you just have to uncover them.

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

If girlfriend were no the critical one to drive your car and the "check engine" irradiate is on, you should start asking questions. Sometimes family members or friends that borrow your automobile spill soda or coffee on the console without informing you. On some Hondas, the ECM/PCM (engine manage unit/powertrain manage unit) is located listed below the center of the console, and also sugary drink can ruin this expensive control unit.

Automatic Scan Tool: compose Down the Code

If you have actually a buddy, friend, uncle, or cuz the can examine the code due to the fact that they have actually a scan tool, make certain you create down the code since if you decide to erase it, you’ll desire to recognize what the was when the irradiate comes earlier on (and if it’s an issue other 보다 a loosened gas cap, the trouble will normally come back). It’s great practice for you and an excellent information to give your mechanic.

Buying a Scan device to analyze "Check Engine" Codes

If you desire to try and diagnose the trouble yourself, you will require to number out v the diagnostic code is informing you. Below is a overview to expertise the codes.

You will additionally need a scan tool. If you decide to to buy on, select one that will last because that years. Vehicles are just getting more sophisticated each year, so arrangement for the future. The OBD2 device covers 1996 and also later cars (the OBD1 device that covers older ones might be included, relying on the device). Ns recommend searching for these four time- and also money-saving features:

A screen that has a summary of the reason of the warning light, and the code. This conserves you time from having to look up the description that goes v the numerical code in a publication or ~ above the computer.LED display screen for state emissions readiness check and drive cycle verification. This feature will permit you recognize if it will certainly pass an emissions test.Battery backup that will keep the password in the an equipment after you disconnect the scan tool, for this reason you deserve to review it and also analyze it away from the vehicle (even if friend forgot to write down the code)A USB cable to upgrade the information in her scan tool from your very own computer. If friend can't upgrade the scan tool, it will be useless in 3 years.
