Hello! I am new to the forums and new to nissans as well. I recently bought a 1996 Nissan Sentra GXE and a couple days after I bought it i noticed the Speedometer was acting up. It would randomly drop to zero and then stay there or it would go back to to the speed. So a couple days after my check engine light came on so i went and had the code pulled and sure enough the code was a speed sensor malfunction. But since Im new too Nissans I was wondering if someone could guide me on how to replace the speed sensor?
