Details of the c1307 OBD Code
C1307 indicates a malfunction in the brake booster pressure sensor circuit.
OBD code C1307 means that the brake booster vacuum sensor has detected a low voltage condition.
This code is triggered by the brake booster vacuum sensor itself when it sends a signal to the ABS module indicating a voltage below the specified threshold.
The brake booster vacuum sensor is a crucial component in the brake system, as it helps the ABS module monitor the vacuum levels for proper brake operation.
Mechanic’s Tech Notes
Code C1307 indicates a malfunction in the brake booster pressure sensor circuit.
To diagnose and fix OBDII code C1307, 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 check connector pins for signs of being broken, bent, pushed out, or corroded.
This can help identify any issues with the TCM circuitry that may be causing the fault code.
