Circuit Diagram And CMP Signal Features

In case of faulty CMP, the TDC signal is analyzed to computing the crank position and engine RPM to further control the fuel quantity and ignition timing. Engine running is available at the same time. There is no engine stall at faulty CMP like existing system. (When the CMP is failed during engine running, the engine stalls, but restart of engine is available by the procedures of operation as IG KEY OFF --> ON)
