Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cold Start Control
During start phase, an increased quantity of fuel is injected 3 times for each cylinder group for up to 5 turns of the crankshaft. This function is dependent upon the engine temperature. This is then followed by a reduction of the initial injected quantity depending upon the temperature and engine speed in order to avoid an excessively rich mixture. If start is repeated within one minute, the total initial starting quantity is no longer injected. During the warm-up phase up to an engine temperature of 158°F (70°C) the injection timing is also correspondingly extended, dependent upon the engine speed and temperature. These values are programmed in the control units.
