1. Disconnect the negative terminal of the battery to avoid any electrical accidents.
2. Locate the speed sensor. In most Honda Accords, it is usually mounted on the top of the transmission, near the passenger side wheel.
3. Remove the bolt that holds the speed sensor in place. You may need to use a wrench or socket to loosen the bolt.
4. Disconnect the electrical connector from the speed sensor by gently pressing the release tab and pulling it out.
5. Clean the speed sensor mounting area to ensure proper installation and avoid any contaminants.
6. Apply a small amount of sealant to the threads of the new speed sensor to ensure proper sealing and prevent leaks.
7. Insert the new speed sensor into the mounting location and hand-tighten the bolt to hold it in place.
8. Tighten the bolt further with a wrench or socket until it is secure.
9. Reconnect the electrical connector by pushing it back into the speed sensor until it clicks into place.
10. Reconnect the negative terminal of the battery.
Please note that if the speed sensor requires a gasket or O-ring for sealing purposes, make sure to inspect or replace it as well to avoid any leakage issues. Double-check all connections to ensure they are secure to prevent any sensor malfunction or damage. If you are not comfortable performing this task on your own or encounter any difficulties, it's best to consult a professional mechanic for assistance.
