Were you using a scanner or the jumper wire & cel method?? If its the latter,you could have accidentally bumped the jumper wire while the code was being output & that would have cleared the 32 code out of the system allowing the system pass "11" code to be the only one showing on the next scan.
If the code was showing up during a koer test,but it was an intermittent fault instead of a continuous "M" fault,the code would not have showed up in the next scan unless the cause for the intermittent issue had been recreated.Example:: if the code was caused by a loose connection,bare wire grounding out,etc the problem would have to be recreated then continue to stay that way before the code would store as a "M" code.
The salt & pepper shakers are also very well known for causing erroneous trouble codes due to a loose or corroded pinout.Do the maintenance procedure in the following link.
