Details of the c1446 OBD Code
C1446 indicates an issue with the vehicle’s brake pressure sensor circuit.
OBD code C1446 means the Brake Pressure Transducer Circuit Range/Performance.
This code is triggered by the ABS module when it detects a circuit range or performance issue with the brake pressure transducer.
The brake pressure transducer is responsible for monitoring brake fluid pressure within the hydraulic brake system.
When the ABS module detects a discrepancy in the signal from the brake pressure transducer, it will trigger the C1446 fault code.
Mechanic’s Tech Notes
Code C1446 indicates an issue with the brake pressure sensor circuit in the vehicle’s ABS system.
To diagnose and fix OBDII code C1446, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using 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 can help identify and resolve the issue causing the C1446 fault code.
