Nissan/Datsun 200SX/510/610/710/810/Maxima 1973-1984 Repair Guide

Electric Choke



The purpose of the electric choke, used on all models, except the 810, and Z20E (200XS) covered in this guide, is to shorten the time the choke is in operation after the engine is started, thus shortening the time of high HC output.

An electric heater warms the bimetal spring which controls the opening and closing of the choke valve. The heater starts to heat as soon as the engine starts.
