My 1999 Honda Civic has the check engine light on the dash. How can I check the codes stored in the computer to see what is wrong with the emissions system? I know i can get a free scan at the local parts store. They always want to sell you the part that the code says is wrong with my Honda,
but have had problems doing that and want to check it first.
Answer: Using a scanner is the best way, but you can do it. Under the passenger side of the dash is a two pronged connector plug. It is usually brown. Use a piece of wire or a paperclip to connect the two. This will put your Honda ECU into code flashing mode. Turn the key to the ON position and watch the engine light flashes. Then find a list of the codes with the number you get. Example: Long flashes mean 10, while short flashes mean 1. So if your car has 2 long blinks quickly followed by 3 short flashes, you have a code 23.
Honda Accord Plug Wires Pops Off
1998 Honda Accord. Question : One of the car's ignition wires keeps popping up (at spark plug end), which causes the dash board's "check engine" light to appear and for engine to run "lousy". Though I keep pushing said wire down, after awhile it pops back up again. What is the problem ?? I thank you very much in advance.
Answer: First thing would be to replace that plug wire, or all of them if you have a lot of miles on your Honda. Next would be to look at the wire / plug when the engine is running to see if it is vibrating or bouncing around. That would indicate a loose spark plug.
1997 Honda Accord. Question: My Honda auto gear blinks light on D4 continuously, also i replace my 4 tires with new ones 14/195 ever since then i have been observing strange noise when i get to pot holes.
Answer: The D4 light blinking on the dash of your Honda Accord signifies that there is a problem with the transmission. First you need to scan the computer for trouble codes. This can be done at most of the large national parts store chains for free. Even if this check engine light is not on there would still be codes. They will tell you what system is having a problem. Whether it be electrical or mechanical internal to the transmission. Changing the tires should not cause a strange noise when hitting potholes unless the new tires are of a very aggressive type. Then you may have a little feel of roughness or grabbing when hitting potholes. I would definitely have the front suspension checked for any loose components. You may have all worn tie rod end, stabilizer, ball joint or any of the bushings and rods in the front end loose.
Honda Radiator Fan Will Not Come On
Question: The fans in my car will not come on unless I unplug the temp sensor at the block (which has been replaced and functions properly). Because of this I had an overheating problem, now I just keep it unplugged, but I'm afraid that the fans being on constantly, I am killing my alternator. Someone told me it may be the cars computer. Any suggestions?
Answer: It could be the vehicle's computer, but there are a few things you should check first. You need to be absolutely positive that the temperature sensor is functional. When you unplug it, you are opening that circuit, so there could be a short elsewhere in the circuit or inside the computer. Normally, the fans should not run with that sensor unplugged. Check the fan relay by switching it with another one to see if the problem is fixed. Try and scan the vehicle to see if there are any trouble codes that lead to the problem. A computer is an expensive guess, so I would check wiring and common things first.
