Circuit description
Refer to dtc p0130
Hint:
the ecm provides a pulse width modulated control circuit to adjust current
through the heater. The heated
oxygen sensor heater circuit uses a relay on the b+ side of the circuit.

The ecm uses the heated oxygen sensor information to regulate t ...
Checking monitor status
Hint:
”monitor result” indicates normal or malfunction of each
component and system when judgment has done.
