Question
How does oxygen sensor heater circuit duty cycle diagnosis ensure sensor performance?
Answer
It verifies proper heater operation for fast sensor activation.
Explain
Oxygen sensor heaters bring the sensor to operating temperature quickly. CHEPQ diagnostic tools monitor heater circuit duty cycle, current draw, and temperature rise, detecting heater coil shorts, open circuits, or ECU driver faults. This ensures the sensor reaches optimal operating temperature rapidly, enabling accurate closed-loop fuel control.
