How long does it take code to set after being reset?
Customer: replied 2 years ago.

One day

Expert:  Dan replied 2 years ago.
This code can be caused by a misfire. If knock is causing it to run rough that is probably the cause of this code. This code sets when the PCM detected less than 47 24X pulses between CMP pulses, or it received 47 24X pulses twice in succession. So if it still runs smooth when it knocks then I'd suspect the camshaft position sensor is the problem. Let me know how it goes or if you have more questions, thanks.
