Circuit Description
In order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor
and carbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen
sensor produces and output signal which indicates the storage capacity of the catalyst. This in turn indicates the
catalyst's ability to convert exhaust emission effectively. If the oxygen sensor pig tail wiring, connector, or
terminal is damaged. Do not attempt to repair the wiring, connector, or terminals. In order for the sensor to
function properly, it must have a clean air reference provided to it. This clean air reference is obtained by way of
the oxygen sensor wire(s). Any attempt to repair the wires, connector, or terminal and degrade the oxygen sensor
performance.

Trouble Area
When recognition the value
less than nominal control
threshold, it means that when
big deviation in control range
of adaptation values through
fuel and air mixture formation
When recognition the value
more than nominal control
threshold, it means that when
big deviation in control range
of adaptation values through
fuel and air mixture formation
When recognition the short
term fuel trim that more than
nominal threshold
When recognition the short
term fuel trim that less than
nominal threshold
When recognition the long
term fuel trim exceeds rich
threshold
When recognition the long
term fuel trim exceeds lean
threshold
When recognition the long
term fuel trim exceeds rich
threshold
When recognition the long
term fuel trim exceeds lean
threshold
When recognition the long
term fuel trim exceeds rich
threshold
When recognition the long
term fuel trim exceeds lean
threshold
