Code P176C Description

The sensor contains a hall-effect sensor and additional electronics that process the signal. It detects the change of the strength of the magnetic field caused by the reluctor ring. When the strength changes, the sensor changes the amount of current it consumes. This results in a square wave signal of the current, while the voltage stays constant. The control module detects the frequency in which the current changes, which is proportional to the rotational speed.
The sensor is an input to the control module. The input signal is used to determine the rotational speed of the component, the Diagnostic Trouble Code (DTC) will be set when the reaction Carrier Assembly Transmission Intermediate Speed Sensor is less than 0.25 V for greater than 1 s.
