- [16186 01](/bulletins/10143749.md), 2018-08-20, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. 16186 01 \- Emission Recall. On certain vehicles equipped with a 1.8L engine \(RPO LWE\), cracking of ceramic components internal to the catalytic converter may occur as a result of higher than anticipated exhaust temperatures. If this occurs, the catalytic converter low efficiency diagnostic will set and the malfunction indicator lamp will illuminate. Dealers are to reprogram the engine control module with calibrations that prevent higher than expected exhaust temperatures. \(service procedure revised\)
