chrisnisbet Posted July 11, 2005 Share Posted July 11, 2005 Hi Has anyone ever had a code 28 fault, and/or know what it means? Apparently, it stands for something like 'ECU fault", which sounds a bit vague (and a little unnerving) to me. Before anyone bleats, I've done a search of the forum, and haven't found any reference to this particular code. Quote Link to comment Share on other sites More sharing options...
wolver1ne516 Posted July 12, 2005 Share Posted July 12, 2005 check out www.troublcodes.net look for the words in blue TECHNICAL-TROUBLE CODES click on it, then select your manufacturers trouble codes. :) Quote Link to comment Share on other sites More sharing options...
chrisnisbet Posted July 12, 2005 Author Share Posted July 12, 2005 Thanks. I'll take a peek. Apparently this code 28 means that there is an ECU fault, and it means replacing the entire thing. I hope that no one else ever gets this code as the ECU ain't cheap. Thankfully, my car is still under warranty. Quote Link to comment Share on other sites More sharing options...
chrisnisbet Posted July 12, 2005 Author Share Posted July 12, 2005 Hmm, on that site, code #28 stands for 'Main O2S'. Maybe the fault codes are different on my Singapore Lexus. Seems a bit odd. Quote Link to comment Share on other sites More sharing options...
