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 Idle Kicker
The cold idle kicker strategy provides an increase in idle speed during cold engine warm up. The PCM uses the engine coolant temperature (ECT) sensor and transmission position as primary inputs, and in certain conditions the PCM uses the ambient air temperature input to adjust the cold idle RPM up to a maximum of 1, 200 RPM (Transit) or 1, 175 RPM (all others).
