the CMP sensor.

CMP (Camshaft position) SENSOR #2
• For DF250 model:
CMP sensor #2 is mounted on the PORT cylinder head cover
with trigger vanes pressed onto the end of the PORT intake
camshaft. This sensor detects camshaft position.
• This sensor is the same type as the CMP sensor #1, and
inputs signals to ECM. This signal is used to control PORT
intake camshaft valve timing through OCV (Oil control valve).
CMP (Camshaft position) SENSOR #3
• For DF250 model:
CMP sensor #3 is mounted on the STBD cylinder head cover
with trigger vanes pressed onto the end of the STBD intake
camshaft. This sensor detects camshaft position.
• This sensor is the same type as the CMP sensor #1, and
inputs signals to ECM. This signal is used to control STBD
intake camshaft valve timing through OCV (Oil control valve).
