Help 1992 2.2 Cavalier

Ran Paper Clip test got following codes and what they mean:

21 TPS voltage was above 3.9 volts for 5 seconds when the MAP sensor signal showed manifold vacuum to be 15 pounds or more and engine speed was less than 1750 RPM or TPS voltage was below 1.9 volts for 64 seconds.



24 When engine speed was between 1400 and 3600 RPM and the MAP signal showed low voltage (high manifold vacuum) for at least 5 seconds.


66 A/C refrigerant pressure voltage was either less than 0.3 volts or greater than 4.9 volts for 5 seconds.


Code 21 should be easy to swap out. But 66 and 24? Also will fixing vacuum ball before TPS replacement take codes away? Fitting at the ball is broke, line is plugged. Also would 66 be reason for heating issue?

Thanks

Swapped TPS out for a jyd model and also did the vacuum ball at the same time. Car runs better. Thanks to everyone for their help.
