Code P1C9B Chrysler Description

This diagnostic compares the output signal of the sensor to threshold values of normal operations. When the signal is out of range the diagnostic will be considered failing. The sensor is mounted next to the 2nd - 4th gear engagement actuator to detect a linear movement of the piston. For this purpose a permanent magnet is mounted on the piston which is moved over a complete travel stroke. The magnet position generates a saturation area in the internal ferromagnetic core of the sensor which is transformed to an output position signal. The sensor provides an output signal with Pulse Width Modulation (PWM) at a fixed frequency and duty cycle proportional to the piston position of the actuator.
