CIRCUIT OPERATION

｠

A  voltage  corresponding  to  the  oxygen
concentration in the exhaust gas is sent to the ECM
(terminal No. 56) from the output terminal (terminal
No.  4)  of  the  right  bank  heated  oxygen  sensor
(rear).

｠

Terminal  No.  2  of  the  right  bank  heated  oxygen
sensor (rear) is grounded with ECM (terminal No.
57).

｠

The ECM applies an off set voltage of 0.5 volt to
terminal  No.  2  of  the  right  bank  heated  oxygen
sensor (rear).

TECHNICAL DESCRIPTION

｠

The output signal of the right bank heated oxygen
sensor (front) is compensated by the output signal
of the right bank heated oxygen sensor (rear).

｠

The ECM checks for the right bank heated oxygen
sensor (rear) output voltage.

DESCRIPTIONS OF MONITOR METHODS

Right  bank  heated  oxygen  sensor  (rear)  output
voltage is under the specified range.
