For the air/fuel ratio sensors, which are located at the right and left exhaust manifolds and detect oxygen density in the exhaust gases, it is possible that the wire inside the sensor gets disconnected. If this happens, the air/fuel ratio is no longer correct because the sensor fails to signal, and therefore the catalytic converter overheats and becomes damaged causing gaseous emissions to increase above the standard level.
Case Number:
RJ-0743-0
Make/model:
Issued:
Tue, 2001-05-29
Component:
gaseous emissions control equipment
Affected:
31 115
Correction:
The right and left air/fuel ratio sensors should be replaced with non-defective ones. Also, the the catalytic converters should be inspected, and the one with damage should be replaced with a new one.
