CIRCUIT OPERATION

｠

Power is supplied from the MFI relay (terminal No.
4)  to  the  left  bank  heated  oxygen  sensor  (rear)
heater.

｠

The ECM (terminal No. 49) controls continuity to the
left  bank  heated  oxygen  sensor  (rear)  heater  by
turning the power transistor in the ECM "ON" and
"OFF".

BACKGROUND

｠

The  ECM  checks  whether  the  heater  current  is
within  a  specified  range  when  the  heater  is
energized.

DESCRIPTIONS OF MONITOR METHODS

Left  bank  heated  oxygen  sensor  heater  (rear)
current is out of specified range.
