Toyota Lexus Ambient Temperature Sensor Circuit
On the front of my Lexus LX450 (not sure if this also applies to the standard Land Cruiser), there's a sensor located behind the grille, plugged into a wire harness. Mine is badly corroded, as you can see in the photo. I've spent hours searching for a replacement on Partsouq but haven't had any luck.
Based on my research, it seems to be the Ambient Temperature Sensor, and while the part. As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system's ability to cool the vehicle. The B1412 code for Lexus vehicles refers to an issue with the Ambient Temperature Sensor Circuit.
This sensor is responsible for monitoring the air temperature outside the vehicle and providing this information to the vehicle's computer system. The sensor plays a crucial role in various systems within the vehicle, including the climate control system, engine performance, and fuel efficiency. This data is used for controlling the cabin temperature.
The sensor sends a signal to the air conditioning amplifier assembly. The resistance of the thermistor assembly (ambient temperature sensor) changes in accordance with the ambient temperature. As the temperature decreases, the resistance increases.
The cooler (ambient temp. sensor) thermistor is installed in front of the cooler condenser assembly to detect the ambient temperature, which is used to control the air conditioning system. This sensor is connected to the air conditioning amplifier assembly and detects fluctuations in the ambient temperature.
This data is used for controlling the cabin temperature. The sensor sends a signal to. 12 AMBIENT TEMPERATURE SENSOR CIRCUIT CIRCUIT DESCRIPTION This sensor detects the temperature outside the cabin and sends the approriate signals to the A/C amplifier.
The B1254 diagnostic trouble code (DTC) indicates a problem detected in the circuit controlling the external (ambient) air temperature sensor. This sensor measures the temperature of the air outside the vehicle, providing essential data for climate control and, in some cases, engine or transmission management. Repair Information for B1412 code.

Learn the 4 signs of a bad ambient temp sensor and what to do next. The B1412 diagnostic trouble code (DTC) refers to the Ambient Temperature Sensor Circuit.
This code indicates that there is a malfunction in the circuit that is responsible for monitoring the outside air temperature. The ambient temperature sensor plays a crucial role in various vehicle systems, including the HVAC (Heating, Ventilation, and Air Conditioning) system, engine performance, and.
