ANSWER: FIRST, CLEAR ALL the codes from the computers.

Next, recheck for codes and as each code displays it will say CURRENT or HISTORY with EACH CODE.

I need to know which ones are CURRENT and which ones are HISTORY.

QUESTION: every thing is History except Code: P085 & T037 Witch is Current.....

Answer
P085 requires cleaning of the throttle body.

T037 requires diagnostics of the wheel sensor.

Go ahead and CLEAR all the codes from the computer and see which omes come back current.

As for the current codes: I can provide pictures and diagnostic procedures if you e-mail me at: onlineautohelp@msn.com.
