Engine can run rough. Possibly poor starting capa-
bility. Engine runs using primary engine position
sensor.
Engine Camshaft Speed/Position Sensor - Data Er-
ratic, Intermittent, or Incorrect. The ECM has de- tected
an error in the camshaft position sensor sig- nal.
Possible engine derate.

information, and maintenance monitor data can be
inaccurate.
Power Supply Lost With Ignition On - Data Erratic,
Intermittent, or Incorrect. Supply voltage to the ECM
fell below 6.2 volts momentarily or the ECM was not
allowed to power down correctly (retain battery
voltage for 30 seconds after key OFF).
