DTC B1461/61 Emission Gas NOx Sensor Circuit

DESCRIPTION

DTC Detection Condition:

The exhaust gas sensor, which is installed on the front of the condenser, automatically changes to FRESH, FRESH / RECIRCULATION, or RECIRCULATION. The exhaust gas sensor detects NOx in the emission gas and transmits signals to the front light ECU (front controller).

The front light ECU (front controller) sends the read signal to the air conditioning amplifier via CAN communication line.

HINT: This circuit uses the CAN communication line. Before performing the inspection, check that the CAN communication system is functioning normally.
