2002 sc2 engine codes

[pete419]

I replaced a bad O2 sensor. Engine light went out. When i went through Inspection and it failed because of STORED codes. How do I clear all stored codes in the computer??

Go to the autoparts store you purchased 02 sensor from and have them put code reader on. Tell them to remove codes. Since you bought from them they should have no problem doing that for you.

Pull PCM-1 and PCM-B fuse or have them cleared at an autoparts store. Some stores will only read codes, not erase them.

+1. Advanced Auto will not clear codes. Not sure about Autozone.

PCM- B fuse under the hood is what needs to be pulled. Re install it after about 5 seconds.

Once you do this you can NOT go straight to an inspection as you will fail again. Not only does this fuse reset the codes but also resents the on board monitoring tests. You will need to drive around for a little bit for all the tests to finish, or you can complete the drive cycle manually if you dont want to wait. I have posted the drive cycle on other threads.
