Section 24.1
Description of SID 64 — Camshaft Position Sensor Fault

SID 64 indicates that during engine operation, a fault occurred with the camshaft position sensor.‪

The Camshaft Position sensor (CMP sensor) senses camshaft position. The camshaft position is used to calculate crankshaft position, specific cylinder positions, and engine speed for functions such as fuel control strategy.‪

The diagnostic condition is typically:‪

  • Open Circuit (64 03)
  • Short to Ground (64 04)
  • Time Out (64 08)
  • Pins Swapped (64 14)

See Figure "Sensor Location on the MBE 900 Engine" for the sensor locations on the MBE 900 engine.‪
