3 problems speed sensor, check engine light, light on instrument panel

A week ago I got in my 91 accord se and started home from work and noticed the speedometer was not working, and then I got a light on the instrument panel that was blinking, an S with a box around it and it's blinking green so I looked it up in my chilton, it says the speed sensor was probably bad,but now its working for the most part, so is it bad, and what is the light, also is it normal to have to change the oxygen sensor about every 6 months which I have been doing, my check engine light comes on and it runs bad and starts eating gas, I've changed the fuel filter, plugs, sorry also my 3rd brake light is not working but the bulb is not blown. Can you possibly help me with these issues

    mine is almost the same problem. my speedometer works fine. but every other time i turn the key on, if that green s light is blinking on my dashboard, the damn thing won't turn over. it doesn't happen in any kind of pattern. very random. if i turn the key and the green light goes off, it starts up just fine. sometimes i'll have to turn the key on 2 or 3 times and it wrks one time i sat in a parking lot(98* degrees, california) for almost 2 hours. l called my husband who luckily drives a tow truck, but wouldn't you know when he turned the key on the light didn't blink and the car started right up. go figure. this is a 1991 accord sw.can't figure it out.

I have a 1991 Accord EX with the same problem.
The speedometer does not work at all and the "S" light continues to flash. I took a chance and went to my local auto wrecker and bought a used VSS (speed sensor) for $20 and that fixed my problem.

I have a 1996 Honda Accord with 268k miles that sputters at the same timethe speedometer needle fluctuates wildly. But I do have a new Vehicle Speed Sensor. This typically only happens when the engin

I am no Honda expert, but a similar problem happened to my ex sister in-laws Ford Taurus. The speed odometer would jump around and it had trouble shifting (automatic transmission). After driving it I changed out the speed odometer sensor on the transmission and it's been fine ever since. I changed out the sensor because if the cars computer cannot tell how fast the car is traveling then fail safes in place go into effect and the computer will do it's best to keep the cars rpm's down based on the speed indicator and not let it shift or shift properly either. If it's getting false speeds then it will shut down the motor when the speed gets to high and allow it to run as the speeds fall (jumping speed odometer needle). It effects the transmission shift points also. It will either shift erratically or not shift out of say 2nd gear, so that the cars engine can't get damaged based on what signal the speed sensor is sending the computer.

Battery's are draining on a 2008 gmc duramax

Check all the interior lights in the truck, look at the visors which are the single biggest cayuse of the battery drain, look at night. Also Have the batteries tested, a shorted cell will draw them down as well. Never overlook the obvious.

Sounds like your O2 sensor is malfunctioning. When the check engine light comes on, the computer goes into a preset mode bypassing the O2 sensor and that's why it suddenly runs good. Have the O2 sensor checked. You can also have the trouble codes read and they should point you in the same direction.

Whilst driving the speedo stops working what is the problem?

Start by checking the vehicle speed sensor. It will likely be listed on your vehicle as an output speed sensor and mounted at the transmission. A bad speed sensor will normally log a code in the ECM and turn on the Check Engine light on the instrument panel.

Dash gauge's on 91 accord are not working rpm speedometer no others at all working what can i check

Hi, you can start by checking all the fuses in the fuse boxes as some of the systems in the vehicles are integrated and getting power supplies through different circuits. If all the fuses are fine you will have to make sure that there is a power supply to the correct connecting points on the cluster. If that is fine the cluster is faulty and should probably be replaced.

Replaced speed sensor, spedometer still not working.

Your instrument is bad, The spiral coil for the needle is alraedy out ot calibration therefore it has been jumping around. Even they reset, it already been stretching. It needs a new one.
Don't waste mony for the reset.
It is probebly expensive from dealer plus labor. Just to check out the price,
You can get a used one from ebay for $85. However, you need to know how to replace it. Let me know it you need any help.
Meanwhile you can gauge your RPM to keep your speed under control on the long trip.For example: 2000 rpm is about 55 mph. Try to keep it below 3000 rpm so you don't get over speed limit.

1991 Accord Code 43 reading

The o2 sensors because the car may have more than one, are located before the catalic converter, they look like spark plugs with 3 or more cables running from the top, scan the car to check for other codes.

91 speedometer and miles

I have a 91 Accord. When I purchased it, the speedometer did not work. I replaced the VSS (Vehicle Speed Sensor) and the speedometer started working again. I paid $24 for the sensor on ebay. The local part stores wanted $150. It's an easy fix. It takes about 20 minutes to replace.
