Post Heating
WARNING: This page is about a different variant/trim than selected.
Post heat is the length of time the glow plugs operate after the engine starts. The Powertrain Control Module (PCM) controls the post heating time based on Engine Coolant Temperature (ECT) sensor output. The post heat phase reduces engine noise, improves idle quality and reduces hydrocarbon emissions.
Preheating is followed by the post heating phase as soon as the engine has started. The post heating phase depends upon how the vehicle is driven.
