Vehicle Fit

If you have had trouble with your Honda Accord or Acura speedometer working improperly or reading wrong then you may need a new vehicle speed sensor.

Our speed sensors are 100% tested to make sure they are working properly at our factory. Random tests are conducted for operating temperatures from -4 to +482 degrees Fahrenheit, proper function to over 60,000 miles, and extreme weather from 250 to -4 degrees Fahrenheit. If any sensors fail these tests the whole batch is destroyed. This ensures the sensor you receive will work properly.

Just put it in today and everything works again. Took some time getting to the old one and installing this one but now my speedometer works and I did it all by myself p.s. people getting this for a Honda Accord Ex VTEC 4L you will need a joint extension for the right bolt its the toughest one ....

Part was exact
This control module was perfect! Fit perfectly and didn’t take any time at all to install! My speedometer just stopped working. Didn’t even check on the check engine light to see what it said the problem was because this 1aauto company had this part so inexpensive we just went ahead and replaced it. So happy!!!

Honda Vehicle Speed Sensor
The price was very reasonable and the part arrived in a few days after ordering. I was able to install the part and it solved the problem, which was no speedometer and a check engine light. This is the second time I have used 1A Auto and am very pleased with their service.

Easy Fix to annoying problem!
Once I diagnosed the issue with my Honda Accord to be a faulty VSS I purchased one online from 1A Auto. Super fast shipping and I was able to install the new VSS in about 30 minutes!!! I now have working speedometer, odometer, and a smoothg running engine. Could not have been a more pleasant experience!!
