This photo shows images of the replacement sensor.

They both match the photos of the speed sensor I purchased on eBay, ebay # 7949439414.

The difference is that my original speed sensor does not have the mounting holes. It appears to sit flush on top of the aluminum housing. Then, over the top of the sensor, there is a thin steel "lid" which has about 4" long springy ears. The ears reach under the housing flange, snapping in place.

With the spring loaded lid removed, I nudged the sensor with a screwdriver. It did not move. It's not clear if I could pry it up and if the replacement could be made to work.

I may be in trouble if I have the only Accord 4cyl auto with the spring mounted sensors.

If it helps, here some information from Carfax.
