I have a 2002 Sunfire and my check engine light is on. My husband has an Xterra and he can check what codes he's throwing without a scangauge by doing some long process with his key and accelerator....! Anyways, is it possible to do this with the Sunfire, or do I need a ScanGauge tool? I used the search and couldn't really find anything, so any info would really help. Thank you in advance!
