Camshaft shift angle, intake/exhaust
Measurement range between -256° to +256°.
The engine control module (ECM) derives the value by comparing the camshaft position with the crankshaft position.
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).
