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?

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)

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.

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
