Description

The crankshaft angular sensor detects and counts the teeth on the crankshaft and provides ECM with the information on the current position of crank angle and cylinder. This signal is fed to ECM to be used to determine the engine speed and adjust the fuel injection timing. The camshaft position sensor detects the teeth target wheel and provides ECM with the information on the current position of piston and cylinder.

This signal is fed to ECM to be used to determine the sequence of fuel injection.

In case of the the crankshaft angular sensor or the camshaft position sensor failure, the engine symptoms will occur a running engine stall, starting impossible and rough idle with noise.

If the CMP signal and the CKP signal is out of allowed limits, the ECM judged this as a fault and DTC is set.
