Details of the c0407 OBD Code
Code C0407 indicates an issue with the right rear wheel speed sensor circuit.
OBD code C0407 means Right Rear Actuator Circuit Low.
This code is triggered by the Electronic Suspension Control Module (ESCM) when it detects a low voltage condition in the right rear actuator circuit.
The ESCM monitors the voltage signal from the right rear actuator to ensure proper suspension operation.
If the voltage falls below a specified threshold, the C0407 code is set, indicating a potential issue with the right rear suspension actuator circuit.
Mechanic’s Tech Notes
Code C0407 indicates an issue with the right rear wheel speed sensor circuit.
OBDII code C0407 indicates an issue with the transmission control module (TCM) power circuit.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage and continuity.
Utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) bus.
Visually inspect wiring harnesses and connectors for any damage, and ensure connector pins are not broken, bent, or corroded.
If necessary, consider reprogramming or reflashing the TCM.
