So this is a re occuring issue ive had for about a week every morning when i go to start my truck its about 35-40 degrees outside i here a slight ticking noise behind the dash panel it shows an engine light and sometimes a little lightning bolt which i think is the ecm??? anyways ill drive to work and for the rest of the day no ticking and usually the engine light disappears..my guess is a weak batterie i got a p2509 and it was a signal intermittent code i was told to check the batterie cables and one was a little loose so i tightened alll of them and cleared it and it went away for a while but early in the morning it still seems to do the same thing.. Any advice or help?? Thanks
