91chevyluminaeuro Posted March 27, 2005 Report Share Posted March 27, 2005 I got a code 13,23&33 when i did i diagnostic on my car today, it seems safe to say that its my ecm, being that that is a common cause for all three codes? a am i right or is there something im overlooking?

Crimson Fury Z Posted March 27, 2005 Report Share Posted March 27, 2005 go see what each code means, and start from 13, unless one of them is a bad ecm code, then replace it. hop over to here http://autorepair.about.com/cs/generalinfo/l/bl_dtcs_main.htmand scroll down to your year and click the make. 13- open oxygen sensor circut 23- MAT low temp indicated 33- MAP sensor circut (high signal) Quote Link to comment Share on other sites More sharing options...
91chevyluminaeuro Posted March 27, 2005 Author Report Share Posted March 27, 2005 yeah that site was about useless, i already have all that information from this site. A bad ecm is on the list as a possible cause for each one of those codes. Quote Link to comment Share on other sites More sharing options...
Crimson Fury Z Posted March 27, 2005 Report Share Posted March 27, 2005 its cheap to do those 3 things. snag an 02 new though. then hop over to a junk yard and get the others, and maybe another ecm. can say at least the haynes is a step ahead of that site, they at least tell you what to replace Quote Link to comment Share on other sites More sharing options...
