Inspect three-way catalytic converter as follows:
^
Looking through the three-way catalytic converter inlet, inspect substrate for blockage. See Figure 1. If total surface of substrate is 10 percent or
more blocked (2 square inches of blockage), the three-way catalytic converter must be replaced.
^
Blockage may not necessarily be located in one spot as illustration shows. The blockage may be spread out across the entire substrate and it may
be necessary to make an estimate of blockages on the total substrate surface.
