The crankshaft angle sensor or the camshaft position sensor can fail and cause loss of engine power, an engine that cuts out, and other drivability problems. This will cause the Check Engine Light to illuminate. Certain models have been involved in a recall to replace the camshaft and crankshaft sensors.

2003 infiniti q45. white smoke out the end of the tail pipe, on start up in the morning. some time poor drive(power) performance. some times motor wont sart.
put a after market camshaft position sensor on my 2001 q45 ran for a month and light come on and when car warmup it would stall.after car cool off it start backup again.
Our car, intermittently will not start. It will crank vigorously but might start after a wait of up to 1 hr. The check engine light has been on for a while, and we have a code for, cam position sensor.
