Need to start from scratch.....clear the codes, make sure memory is clear (run KOEO to verify), verify TPS output with a voltmeter, test drive it for 10 minutes, and rerun a KOEO and a KOER self-test. Those codes may have been logged in memory if you disconnected any of the sensors while the engine was running (= false codes).

+ if the codes are a repeat......you would need to monitor their voltage output under driving conditions, and/or do a "wiggle test".
