Electric Assist Choke: Description
All passenger cars, except Omni and Horizon, are equipped with an electric assist choke, as described in this article, to help reduce emissions during engine warm-up. Two different electrical control units are used to regulate the choke heating element: a dual-stage control to assist engine warm-up in summer and winter operation, and a single-stage control which shortens choke on time during warmer weather only.
NOTE:
Omni and Horizon use a "Full Electric Choke" system. See appropriate article in this section.
