It monitors engine coolant temperature and reports it to the vehicle's control system, which uses that reading to help manage fueling, cooling, and the temperature gauge. It's a direct-fit replacement for the 1978-1981 Nissan 810 and the 1980-1983 Nissan 280ZX — see the Buyer's Guide tab for the full engine-level applications.
