this afternoon, I got my CEL lit on...I pulled out the codes and there were 2 codes..: 05-10 and 05-12...05-10 means that the rear o2 sensor is gone (or other things such as the injectors, fire or something else is wrong) but I alson had the 05-12 wich means ??? never seen this code before and can't figure out what it is... anyway I resetted the ecu and the codes went away and the CEL's still not ON 'till now...

please help!

 

the 0510 is o2 sensor? if so I'd change and reset the ecu, not sure what the 0512 is but it maybe tied with the o2 sensor, so when you change and reset that both problems could be fixed. Or maybe getting codes scaneed at a local auto store free and see what their scanner/print out says.

 

probably related to the o2 sensor but anyway, that code went away and my max is pulling better than ever...we'll see what happen next...
