1 code could cause 4 others to come on. But with only 1 issue. Example, my sephia when we first put a cai on it, we broke the iat wire. Car started doing all sorts of bad things, stall, bad idle, no power. scanned it, got 6 or so codes. Low and behold, replaced iat wire, all 6 or so codes were cleared after reset.
Look at each one, could be as small as my issue was but got multiple codes. With needing only 1 fix.
