Guide a 12 mm socket with two 10" extensions down onto the bolt. You will need to carefully work the socket and extensions between wires and hoses, being careful not to put too much tension on them. Turn the bolt counter-clockwise until it completely un-threads.

Pull the vehicle speed sensor out of it's hole. Be careful to not bump too many parts while removing the sensor, as you may knock debris into the transmission which can cause premature wear or failure. To avoid the risk of damaging the wiring harness, do not pull the sensor by its wires.

Hey I raplace the speed sensor but my speed gage it still doesn't work, any other Ideas what else can it be?

Christopher Reyes - Reply

Try getting a manual (Haynes?) and check the wiring as suggested. Maybe try a different gauge cluster?

Detach the sensor cable before pulling the sensor out. I used 2 shorter extensions and went at it from the side. Clean around the sensor before you take it out.

I have a sort-of related question: this air intake hose - does it have another opening underneath? The one in my 1998 Honda Accord EX 4-cylinder needs to be replaced, but the only ones we can find have extra open ports. Thanks for any info and advice!
