Details of the c1451 OBD Code
Code C1451 indicates an issue with the brake pressure sensor circuit in the vehicle’s ABS system.
OBD code C1451 indicates an issue with the vehicle’s brake pressure sensor circuit.
This code is triggered by the Electronic Brake Control Module (EBCM) when it detects a circuit malfunction related to the brake pressure sensor.
The brake pressure sensor is responsible for monitoring the hydraulic pressure within the braking system.
When the sensor circuit fails or malfunctions, the EBCM will set code C1451 to indicate the problem with the brake pressure sensor circuit.
Mechanic’s Tech Notes
Code C1451 indicates an issue with the brake pressure sensor circuit in the vehicle’s ABS system.
To diagnose and fix OBDII code C1451, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) network with a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection will help identify and address any issues causing the C1451 fault code.
