Details of the c0090 OBD Code
Code C0090 indicates a fault in the right rear ABS wheel speed sensor circuit.
OBD code C0090 means Right Front ABS Solenoid #1 Circuit Short to Battery.
This code is triggered by the AntiLock Brake System (ABS) module when it detects a short circuit to the battery in the circuit related to the right front ABS solenoid #1. The ABS solenoid is responsible for controlling hydraulic pressure to the right front wheel during ABS operation to prevent wheel lockup.
Mechanic’s Tech Notes
Code C0090 indicates a fault in the right rear ABS wheel speed sensor circuit.
OBDII code C0090 indicates a problem with the Transmission Control Module (TCM) power circuit.
To diagnose this issue, use a multimeter to check the TCM power and ground connections for proper voltage and continuity.
Additionally, use a scan tool to communicate with the TCM over the Controller Area Network (CAN) network to verify its responsiveness.
If the wiring harness or connectors appear damaged, inspect them closely for issues like broken, bent, or corroded pins.
Reflashing the TCM software may be necessary to resolve the fault.
