Details of the b0223 OBD Code
Code B0223 indicates a fault in the HVAC system temperature sensor circuit.
OBD code B0223 means Temperature Control #2 Circuit Malfunction.
This code is triggered by the HVAC control module when it detects a malfunction in the circuit related to controlling the temperature for a specific zone or component in the vehicle’s HVAC system.
The circuit involved in this case is specifically related to the second temperature control circuit, which could be for a particular zone or component within the HVAC system.
Mechanic’s Tech Notes
Code B0223 indicates a problem with the ambient light sensor circuit in the vehicle.
OBDII code B0223 indicates a problem with the temperature control #2 circuit in the HVAC system.
To diagnose, use a multimeter to check for proper voltage at the temperature control module (TCM).
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
Inspect wiring harnesses and connectors for damage, and check for broken, bent, or corroded pins.
If all checks out, consider reprogramming the TCM.
