clearing codes...

[bigpappy]

After much effort and expense, I thought I had my SHO all ship-shape. I ran the codes, and all I came up with was 111,111, 1, 332 (KOEO)
I had already cleaned the crap out out of that little passage way...
So, I guess my question is this: Is there more than one way to clear codes? I've heard to take the paper clip out while running the codes, I've heard tap on the brake light with the negative cable off. I also heard that after 10 cold starts, the computer will reset itself. (Start up, run to operating temp, shut down, cool off, repeat 10X) -- That sounds really lame to me.

Yesterday, I heard a guy tell me that he was a former Ford Tech. He said that those steps will work with some, not all. He said to disconnect the battery completely for 15 minutes. Sure, it was over beer. In a sober light, disconnecting both cables might make sense, but why 15 minutes? Residual current?
Also, is it true that Autozone can clear the codes through their nifty tester device?

Thanks,
John

If you remove the paper clip while the codes are flashing it will remove the stored codes. He probably said disconnect it for 15 minutes because of any "juice" left in the computer, you can also press the brake pedal with the battery cable off for like a minute or so to drain it. Best bet would to be remove the paper clip while the codes are flashing and then immediately rerun the codes to verify that the stored code was released from memory.

The paper clip works fine. When using the "tester", the operator is required to flip a switch at the proper time to clear the codes. Same thing.

Disconnecting either battery cable is sufficient. All you have to do is to remove power from the circuit and allow enough time for the charge held in capacitors in the PCM to be discharged. Usually at least one beer's worth. Pressing and holding the brake pedal drains these charges quickly.

If you SEARCH on "332 DPFE" and my user number, you will find a procedure to diagnose the 332 error instead of just guessing that it's clogged intake ports.

Run the KOER test to see if the 332 comes up in the diagnostics.
