Camshaft Shift Angle, Intake/Exhaust
Measurement range between -256° to +256°.
The engine control module (ECM) calculates the value by comparing the position of the camshaft with the position of the crankshaft.
The value indicates the offset of the camshaft position in relation to the crankshaft TDC (0). (The camshaft 0-position = the camshaft position set alignment with the crankshaft TDC).
