DTC: Diagnostic Trouble Code, a code that indicates a specific problem in the vehicle.
• B0120
• B0121
This code means there's a problem with the temperature sensor inside your car. It's like when a thermometer isn't working right and can't tell you how hot or cold it is.
The code B0119 indicates an issue with the interior temperature sensor circuit.
B0119 is a diagnostic trouble code (DTC) for a malfunction in the interior temperature sensor circuit. This sensor measures the temperature inside the vehicle and sends this information to the climate control module to help regulate the cabin temperature.
• Check for any other related trouble codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the interior temperature sensor for proper operation.
• Replace the faulty interior temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the climate control module if necessary.
