Circuit description
The rear heated oxygen sensor is used to monitor oxygen concentration in the
exhaust gas. For optimum
catalytic converter operation, the air fuel mixture must be maintained near the
ideal ”stoichiometric” ratio.
The heated oxygen sensor output voltage changes suddenly in the vicinity of ...
Basic inspection
When the malfunction is not confirmed in the dtc check, troubleshooting
should be carried out in all the
possible circuits considered as causes of the problem. In many cases, by
carrying out the basic engine check
shown in the following flowchart, the location causing the problem can be found ...
