Details of the b1225 OBD Code
Code B1225 indicates a problem with the temperature blend door actuator circuit.
OBD code B1225 means Sunload Sensor 1 Circuit Short to Ground.
This code is triggered by the HVAC (Heating, Ventilation, and Air Conditioning) module when it detects a short to ground in the circuit of the sunload sensor 1. The sunload sensor measures the intensity of sunlight entering the vehicle and helps the HVAC system adjust the temperature and airflow accordingly for occupant comfort.
Mechanic’s Tech Notes
Code B1225 indicates a problem with the temperature blend door actuator circuit.
To diagnose and fix OBDII code B1225, 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 corrosion, bending, or breakage.
This thorough inspection can help identify and resolve the issue causing the B1225 fault code.
