P0382 Glow Plug Circuit B Malfunction Low
The P0382 code means the computer found a fault in glow plug circuit B, the group of glow plugs fed by the second circuit on engines that split them in two. The usual culprits are a burned-out glow plug, a bad relay or output, or corroded wiring. The engine still runs, but cold starts get hard and the exhaust shows white smoke.
