P0049 Turbocharger/Supercharger Turbine Overspeed - General Information

Component Location





General Description

The turbo charger uses exhaust energy to rotate the turbine. The turbine rotates the compressor to the axis in order to compress the intake air. The compressed intake air is cooled through the intercooler, and provided it with the engine. The efficiency of the engine increases (NA compared 30 - 40%) and also drops the quantity of harmful exhaust gas.

DTC Description

PCM sets DTC P0049 if the ECM detects that turbine speed of turbo charger is more than 172,000 rpm.
