Ecu Code 28

[chrisnisbet]

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.

check out www.troublcodes.net

look for the words in blue TECHNICAL-TROUBLE CODES

click on it, then select your manufacturers trouble codes. :)

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.

Hmm, on that site, code #28 stands for 'Main O2S'.

Maybe the fault codes are different on my Singapore Lexus. Seems a bit odd.
