Hey guys can someone give me a hand with the trouble code of 28. I got the check engine light yesterday on my way home, so I pulled the code form the car when I got home and it flashed 28. I have a SupraTT and checked the code in the MKIV service manual and 28 reads sub main O2 sensor is failing. I think the SC300 also uses the same trouble codes as the Toyota Supra since they are made byt he same company, but if anyone can tell me for sure what code 28 is from the SC300 service manual. Thanks

It looks like your engine code means the #2 oxygen sensor.

Thanks buddy for the great Link, so it seems the MKIV and the SC300 do indeed share the same engine codes. Bad No.2 sensor, oh well I will pick a new one up soon. Again thanks for the help.
