What Does the P1891 1996 Honda Civic Code Mean?

The start clutch control system controls the clutch piston hydraulic pressure which affects the amount of power transmission by the multiplate wet start clutch on the driven pulley shaft. The Transmission Control Module (TCM) activates the CVT start clutch pressure control solenoid to control the hydraulic pressure that is applied to the start clutch piston in accordance with vehicle conditions. The start clutch control system detects the overslip of the clutch. If the difference between the vehicle speed measured by the driven pulley speed sensor and one measured by the CVT speed sensor is excessive when driving the vehicle under Enable Conditions, a malfunction, excessive clutch slippage is detected and a DTC is stored.
