Damn, jimberg beat me again!!!!!!!!
 You're supposed to have it up to operating temperature when performing a KOER test, and for extra measure the EGOs should be up to temperature as well (so it's in closed loop). This consists of running the engine at 2000rpm for 2 minutes, AFTER the engine is up to op-temp. Charles Probst's book says Code 21 means 'ECT our of Self-Test range.' Did you just get this code during the KOER test only or in the KOEO, too? If the engine was cold, redo the test and confirm the results.
