Start Clutch Pressure Control
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
The hydraulic-controlled start clutch, like a torque converter, controls smooth starting-off and creeping in D, S, L, and R. The PCM inputs signals from the sensor and switches, and actuates the start clutch pressure control valve to regulate the clutch reducing pressure, and the clutch reducing pressure controls the start clutch.
