Camry 2001 P0420 check engine light issues
Does anyone has a fix for Camry 2001 P0420 check engine light issues? I did replace Front sensors ie: A/F ratio O2 sensors Toyota Brand, did replave Front CAT, and still has CEL on???
first try to reset the code and see if it reappear again, if it does the only known fix with out those you already done is the wiring....
