Details of the b0102 OBD Code
B0102 code indicates a malfunction in the passengerside airbag sensor circuit.
OBD code B0102 means Fuel Sender Circuit Low Voltage.
This code is triggered by the Body Control Module (BCM) when it detects a low voltage condition in the fuel sender circuit.
The fuel sender circuit is responsible for sending the fuel level information to the BCM, which then displays it on the instrument cluster for the driver to see.
When this circuit has low voltage, it can lead to inaccurate fuel level readings on the dashboard.
Mechanic’s Tech Notes
Code B0102 indicates an issue with the passengerside airbag sensor circuit’s voltage being too low.
OBDII code B0102 indicates an issue with the TCM power circuit.
To diagnose, use a voltmeter to check power and ground connections to the TCM.
Verify TCM communication over the CAN network using a scan tool.
Visually inspect wiring harnesses and connectors for damage, focusing on pin condition for signs of corrosion or damage.
Reflashing the TCM may be necessary.
Ensure all connections are secure and free of corrosion.
If the issue persists, consider consulting a professional for further diagnostics.
