Function Explanation (DTC Detection Outline)

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

The PCM calculates the rotation speed of the clutch based on the signal input from the revolution sensor. The engine speed and clutch rotation speed match while the clutch is engaged and the vehicle is being driven. However, if the difference between the engine speed and clutch rotation speed is the specified value or more while the clutch is engaged and the vehicle is being driven, the PCM determines a malfunction in the revolution sensor and stores a DTC.
