Trouble codes won't clear

Hi,

Not sure how much of a help I can be.

I will relay this: On the po102 code, I know of one that was fixed by replacing the cam sensor and setting the distributor to 0. I don't have the testing info that brought it to this, but I thought it was worth passing along.

If you are just looking to clear the codes, an OBD tool that is able to be programed with vehicle specific information is the best route.
You can usually clear these codes by disconnecting the battery for a predetermined amount of time. I'd play it safe and leave it completely unhoked overnight.
Hope that helps you get the codes cleared for you.

HEy guys,

30 seconds is the required time for disconnection to clear the codes. However clearing them may be futile. The codes sound like they are not going to go away. Clearing the codes just erases the pcm short term memory heh, kinda like a quick case of alzheimers. The pcm goes through monitor checks that are self tests of a sort for various emission systems or things that will affect emissions anyway. The problem with clearing them is if you opt to take it to shop they have less to work with as they can access the freeze-frame data that shows what the data stream produced at the time of the monitor failure that turns the light on. Some monitors won't run until a particular code is addressed and sucessfully solved. So, clearing those codes if possible may muddy up the situation. Or may not :roll:

Brother Dip: your'e an awsome addition to the forum moderators. I have no clue to the programming lingo you use, but opens up another avenue of understanding :wink:
