P1d6b Jeep Description

This diagnostic compares the odd clutch actuator position to minimum and maximum threshold values when the odd clutch electrovalve command is off. In this situation the clutch is supposed to be closed. The threshold values are defined based on the mechanical design: the odd clutch closed position changes as a function of the clutch life and of the manufacturing tolerances. The actuator position is read by a position sensor which provides an output signal with Pulse Width Modulation (PWM) at a fixed frequency and duty cycle proportional to the position of the actuator. The PWM duty cycle electrical range is between 10% and 90%. If the position sensor signal indicates that the actuator position with electrovalve off is outside its expected range then the diagnostic will be considered failing.
