2003 Chevrolet Silverado Repair Question
TC PO442 how do I do a drive cycle and cold start
Thanks Robert C. Lowry @ firstname.lastname@example.org
So the code is gone and hasnt come back and there are no other codes set?I need to know that before answering your question.
That is correct. The code hasnt come back and no new codes have been set. I am however trying to get the Evap System Monitor to reset. It is showing incomplete. The Chev dealer told me I need to do cold starts and drive cycles to get it to reset.
Thanks Robert C. Lowry
Forgot to ask you what size engine do you have?
I posted the drive cycle to reset all the monitors.
Does your code reader show if the monitors are ready or complete?The evap one sometimes takes a little while to set the monitors.Are you trying to smog the truck?
Thank you I will try my luck.

yes I am trying to get it smogged. It has passed the emissions test and was failed on the evap system.
Alright it usually takes a few trys doing the drive cycle its better if you have a scan tool that can check to see if the monitors are set.Let me know how you make out.
my scan tool tells me if my I/M monitors are set. I have the one to go. Thanks I will let you know how I come out.
