Electric Variable Valve Timing Driver Control Inspection

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.

Perform the KOER self-test. If the following DTCs are detected, repair the applicable malfunctioning location according to the applicable DTC troubleshooting. (See DTC INSPECTION .)
- P0010:00, P0011:00, P0012:00 or P1380:00
Access the PCM PIDs [VLV_TIMING_ACT_IN] and [VLV_TIMING_DSD_IN] using the M-MDS data monitor function.
WARNING:
- When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
- While performing this step, always operate the vehicle in a safe and lawful manner.
Drive the vehicle (accelerate/decelerate and drive at constant speed), and verify that the PID [VLV_TIMING_ACT_IN] value changes in conjunction with the PID [VLV_TIMING_DSD_IN] value.
- If the change cannot be verified, replace the electric variable valve timing motor/driver. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION .)
