Code B1412 2015 Toyota RAV4 Description
The air conditioning amplifier assembly applies a voltage (5 V) to the Cooler Thermistor (Ambient Temperature Sensor) and reads voltage changes due to changes in the resistance of the Cooler Thermistor (Ambient Temperature Sensor). The combination meter assembly sends the read signal to the air conditioning amplifier via CAN communication.
The Diagnostic Trouble Code (DTC) will be set when the Air Conditioning Amplifier Assembly detects an open or short in the Cooler Thermistor (Ambient Temperature Sensor) circuit.
What are the Possible Causes of the DTC B1412 2015 Toyota RAV4?
- Faulty Cooler Thermistor (Ambient Temperature Sensor)
- Ambient Temperature Sensor harness is open or shorted
- Ambient Temperature Sensor circuit poor electrical connection
- Faulty Air Conditioning Amplifier Assembly
How to Fix the DTC B1412 2015 Toyota RAV4?
