Details of the c0131 OBD Code
C0131 pertains to a malfunction in the ABS pressure sensor circuit.
OBD code C0131 means that a malfunction has been detected in the ABS/TCS system pressure circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects an issue with the brake pressure sensor circuit.
The EBCM monitors the brake pressure sensor to ensure proper brake system operation and to assist with traction control functions.
If the EBCM detects a fault in the brake pressure sensor circuit, it will set code C0131.
Mechanic’s Tech Notes
Code C0131 indicates a fault in the ABS pressure sensor circuit.
OBDII code C0131 typically indicates a fault with the ABS/TCS system.
To diagnose, check the TCM power and ground using a multimeter.
Verify TCM communication over the CAN network with a scan tool.
Inspect wiring harnesses and connectors for damage, corrosion, or loose connections.
Ensure connector pins are intact.
Reflashing the TCM may be necessary.
This code often points to issues with the transmission control module (TCM) or its circuitry.
Conduct these tests to pinpoint the exact cause and proceed with the appropriate repairs.
