Welcome to Techauto Honda Acura E R (the Honda emergency room for electrical repairs)
Word from the author:
Thanks for visiting this site and thanks for visting our sponsors. Because of this,
our website has been kept alive throughtout the years. This website will be moving to www.techautorepairs.com
soon due to overtraffic. And finalized by Nov 9, 2009. Hopefully, the site has empower yourself to solve your own problem and not
rely on a few mechanics that may inflate the prices on you, pull a fast one or have not abide by
the rule of fairness, of honesty, the code of ethics and the disregard to the environment or to the economically challenged. Hopefully, as you
begin to understand how a car works you'll notice how polluting and inefficient
they are. Only 1% of the energy from the raw fuel is use to propel the the
car. We love to see all of us love the Earth and have compassion for life - don't pollute or overpopulate
and do advocate for alternative energy and environmental friendly vehicles.
These instructables found on this website only makeup about 10% of the
all the parts that can be rebuild. Hopefully it will encourage people to
drive fuel efficient cars that are rebuildable. As far as we know only the Honda
and the Toyota have made it very simple to rebuild. But, I'd much prefer the
Honda because this is a car company that is much more friendlier to the
environment compared so some the recent bankrupt car companies.
Some electrical components found in the Honda (Acura) are also used in the medical industry. This
had showed me the compassionate side of Honda because most medical components
are carefully selected so that they are reliable and biologically safe to be
touch. You'll notice that Most Honda parts are symmetrical and round with little
or no right angles or sharp corners. They mimic biological parts. And curve parts aren't easy to
make. I like to see more people support car comapnies that value life.
Please take care of your cars, as each Honda (in my heart) are my children. (I don't have children, btw,) I
love to see your cars well and not pollute. Unfortunately, I currently cannot help anyone diagnose their cars
as I've switch into a different line of industry and 'welded the hood of my Honda shut.' But there are a
fews guys (and gals) who update this website regularly for clarity and who answer our emails once in a while.
Respect and love your Honda and they will last
you 20 years or more. Always keep the hope that your car will bring you home....
and, like a reliable parent with integrity, they will always do. :)
Techauto.tripod.com, created in 1999, is website designed for the only purpose of troubleshooting Honda or Acura (mission) critical electrical problems. Problems that may destroy personal property or cause the vehicle to stall or become stranded. Namely, the ignition, fuel and the cooling system are considered the essential systems. Because troubleshooting these systems usually require an electrical diagram for each make and model, we put every effort to allow you to figure out how your system operates by showing you the basic electrical diagram.
This site is about the positive side of troubleshooting and not about the negative flaws of the Honda. In fact Honda is one of the most reliable car makers in the world with the highest resale value. We hope that these support information will ease your car ownership. In return you are contributing to environment by driving an enviromentally friendly car.
Why don't we cover more mechanical problems? The answer is that mechanical problems are intuitive, electrical problems aren't if you've just happen to stumble onto the problem and you want nothing else but to have your car run. Because not every everyone understand electronics, a step by step and a flowchart are develop for them. For those who understand circuits, then an unlabeled diagram can still be useful. This site has just the mission critical electrical diagrams for the willing observer.
Soichiro Honda's dream is to bring the highest quality, reliable car for the world at an affordable cost. But today's repair cost is beyond the practical car owner. We've compiled some important information which are specially designed to troubleshoot the Honda or Acura so that any stranded vehicle will be able to get their car moving without guessing which parts had failed. Some of the tips even explain how to fix some of the bad parts. And most tips are "the secret of the trade." The fixed parts are tested and proven before they are presented here. These advices are honest, fair and to the point which is designed to save you up to $40- 100USD or more per repair. At your discretion, you can even provide the author some loose change to improve the information see donate link below. Thank you.
The Honda Accord and the Honda Civic are one of the most highly purposeful, practical car in the world, based on our observation on the previous generations of vehicles. The characteristics of these cars are the engine longevity and performance. In its own class, the Civic is well known for its road performance, reliability and cost effectiveness. The civic is easy to maintain due to its smaller components. Although this site is not about tuning, the information here can get that car back on the road, helping to continue Soichiro Honda's dream. Early Civic Engine blocks can be lifted by two people (not lifting from the engine bay) and the head by one person makes the Civic an easy car to maintain. Never lift anything unless you are sure that you can do it safely using proper lifting techniques. Always and lift with your knees.
Prevention: The Honda/Acura have precision motors and drive-train. The parts are machined to the highest standards. Once repaired incorrectly they will never be the same. Because of this, prevention and maintenance are the key to their longevity. The motor is the most important part of the car, second being the transmission. Here are two important awareness to keep in mind.
- Pull over to a safe spot and shut off the engine if the oil light is flashing. Shut off the motor right away if the oil light is on.
- Pull over to a safe spot and shut off the engine if the temperature needle is climbing. Shut off the motor right away if temperature needle is on or above the red mark - when safe to do so.
Other precautions:
- Avoid aftermarket parts if they are gaskets, seals or parts that contains wax, rubber or parts that will be subjected to oxidation, unless they're proven to be equal to Honda's quality.
- Don't put fluid additives on your transmission, or contaminate the fluid with dirt or debris. (Keep in mind that under severe conditions the ATF are service twice as often.) Change the oil early if it's dark or black. Consider putting an inline ATF filter if you have a 90-93 Accord. Use Honda ATF whenever you can afford it. And if stuck in snow, tow. Do not shift to neutral at every stop and avoid shifting from R to N while the car is moving.
- Don't allow the car to overheat. See overheating.html#whattodo to learn how to protect your investment.
- Don't do jack rabbit starts without, fresh oil, oil flter, air filter on a warm engine.
- Do drive at the highway often to clean the motor of deposits.
- Many more...
Guessing which parts to replace is inefficient, considering that some parts can last the life of the car. This site and other sites may be able to take the guessing out of replacing parts. This site has moved from its old server when updating the pages on the previous server became too difficult. If you find difficulties with the URL please turn on your Javascript to correct the url. If you find difficulties with the popup ads, turn off your JavaScript.
Safety when testing parts: Most electrical test on this site requires no special tools because we try to keep the practical users in mind. Thanks to the safe designs by the Honda Motor Co., the tests on this site are safe if you're careful and use common sense. Some of the the best electrical tools are built right into the car. The spare light bulbs in your trunk or in your cabin are some of the most precise measuring tool. The LED in your dash buttons is another decent tool for measuring computer signals. What you didn't have are the electrical diagram of the cooling, fuel and the ignition system. The three basic systems that keep the modern car moving. Essentially, your car came from the factory complete except for the wiring diagrams. In fact, even your washer and dryer are shipped with an electrical diagram.
Basically, with prior knowledge of electronics and a little bit of brainstorming, this site has the capacity to trace and troubleshoot the 92 Accord fuel, cooling and ignition system without the need for the special harness tool provided by Honda.
Essential traveling tool kit:
a) an 8mm socket that fits the distributor cover bolt.
b) a 10mm socket
c) a 12mm socket
d) a 14mm socket
e) a 17mm socket
f) a 19mm socket
g) a 13/16" or a 5/8"socket for plugs
h) a cheater pipe
j) an extension no greater than 5"

Essential traveling electrical part kit:
a) Distributor rotor
b) Igniter (aka ignitor)
c) Coil
d) Probably a fuel pump.
e) If your vehicle is over 150k miles you might want to consider resurfacing the communtator and replace the alternator brushes.
f) Other electrical parts will also fail but most often they can be revived on the spot.
The test light is one of the versatile tool but it wouldn't hurt to carry a DMM or Voltmeter/Ohmmeter with you. Make sure that your DMM is a high impedance version when working on computer signals, not all DMM are the same and not all are accurate. And please note that problems which aren't mission critical are usually not posted on this site.
Anyone that's willing to learn is assumed a pro. So, if you find the instructions a little confusing, not detailed, substandard, unprofessional or requires photographic pictures you can post a comment for improvement purposes. I may find someone around my desk here to take some snapshots for this site.

bozz boorer: how can I join in? - I have a ignitor problem. Done your test & the wht/blu wire did not lid up. So I took the ignitor to test at the shop & it was bad. I purchased a new one- then it did it again. does not start & does not light up? Please advise. Admin: Joining was disable for now becuase there are no moderators. They all went out of town. :-( - - - Okay, make sure you connect the test light to wht/blu and ground then crank. If it blinks using the new igniter then the coil's dead. If it doesn't blink then listen for the clicks on your injectors when you crank it up. If you don't hear the clicks then make sure the main relay and distributor sensors are in good shape. Don Massie: Awesome Info guys cant wait to fix my main relay! - anybody have a problem with start your 90 accord up and a cloud of oil smoke pluems out the tail pipe like you just blew a head gasket then it don't do it for next 20 cold starts the out of the blue smoke cloud from hell? Admin: Thanks. - - Logic tells me that if you see blue smoke then you are consuming some oil. The blue smoke is from a leaking valve guide that allows oil to slowly run into the cylinder after it sets for a while. Keep a watch on your oil. - - One of guys here says he'd did the valve stem guide right on the car. Tosha: I have owned three 91 Acura Legends i love them, my most recent won't start because of the D4 light won't come on. If I bang around it starts. Please save my car! Admin: This is somewhat confusing. When it won't start do you hear the starter motor spinning? Now, does the check engine light come on then go off normally? Do you hear the fuel pump for the first two seconds you turn on the ignition? - - - People tend to leave out details when they say it won't start. The best way to say that you hear the starter motor working fine is, "it cranks but won't start". If you don't hear the starter working at all you might want to say, "it won't crank but I hear a click (include how) from under the hood." What technicians want to hear is all the symptoms such as smell, sound, sight. But if you're a techie, the technicians will want to know the voltage, current, and their activities. This eliminates guessing. Knowing how to ask will help us solve your problem much faster. - - And by the way, you might want to check the 'won't start' flow chart first. It takes you thru basic starting and helps you solve simple problems first. It can be found here http://techauto.awardspace.com/ignition.html#flowchart nmramli: brake lamp indicator and parking indicator lamp always on... - why...... techautosteve: See what you can do with this info: Honda 'brake warning light' is on when hand brake switch is on and fluid switch is low. 'Brake lamp indicator' only comes on when stepping on the brake for the first time. If brake lamp comes on at the same time as the when the car starts and idle then their is most likely a short in the instrument cluster. - - Remove the instrument gauge and disconnect each wire until the light goes out (a diagram will speed things up.) This can help you see if the problem is inside the cluster. Anonym: oil fiter gasket Pak: Transmission only works when car is cool, no blinking "D" or "S" in 1991 accord. Once the car is warm, transmission will disengage and car won't move anymore.
