you dont need to put it on the diagnostic machine to check for codes, the cars does it for you if you jumper the Te1 and E1 terminals in the diagnostic block, searching the site will ield more innformation regarding this...and you will have the true codes
thanks for all of your help. i gt my real codes: 21, 34, 41, and 52. also, i wanted to ask if this is stored codes from past problems as well. because this is my 4th motor in this car. is it possible that the ecu was never clear and its storing old codes as well?
It is not the ECU that is neccessarily the problem.
21 is O2 sensor, check it according to the TSRM.
34 is boost pressure abnormal = fuel cut or air flow meter.
41 is TPS, check it according to TSRM.
52 is knock sensors, most likely the wiring goto www.supras.com/sogi and look up the tech tips for a rewire tip.
