| F0U_Supplemental | 2018-04-23. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR. TI: Background-In the subject vehicles the front catalytic converter internal components may become deteriorated and begin to rattle. If continually operated in this condition, the deteriorated components could become dislodged and restrict the exhaust flow. If this occurs, the vehicle may illuminate a check engine light, and, depending on the level of exhaust restriction, the vehicle may experience a reduction in power. Toyota has developed a new exhaust pipe with catalytic converters to prevent this condition from occurring. |
