B1604 CHRYSLER, DODGE, JEEP, RAM: RIGHT SOLAR SENSOR CIRCUIT LOW
The Solar Sensor is a device that is installed on the top of the instrument panel. Its purpose is to detect sunlight so that the A/C (Air Conditioning) AUTO mode can be controlled. The Solar Sensor has variations in its output voltage, depending on the sunlight. If the light level is high, the voltage tends to increase. If the light level decreases, the voltage also decreases.
The HVAC (Heating, Ventilation, and Air Conditioning Module) adjusts the operation of these systems by using the information provided by several sensors, including the Solar Sensor. If the input voltage of this device is out of range towards the low voltage threshold, the B1604 OBDII fault code will be set.
Reasons to set the B1604 OBD2 diagnostic code:
