Diagnostic Codes 200 1991

On my '91 240, The following codes showed up:

fuel injection:

2-3-2 fuel system compensating for rich or lean mixture at idle

ignition system:

2-1-4 speed sensor signal missing or sender faulty

The car runs fine, but when the meather is hot and humid, it needs a little gas pedal pressure to start.

I don't know if these are old codes, how do I clear them?

The method in the Hayne's manual didn't work.

Where's the speed sensor and how do I check it?
