What does "bad reading" mean? The engine won't run if that sensor isn't working.
If coasting for seven seconds didn't solve this, do it again while holding the brake pedal up with your toes. Sometimes the pedal will vibrate, and if one part of the brake light switch turns on momentarily, the relearn will be aborted.
The next step is for your mechanic to use his scanner to test the idle speed motor function. That will allow him to run the idle speed up to 2000 rpm in 200 rpm increments. That will prove the system is working and the air passage isn't blocked with carbon. If the idle speed doesn't increase or if the scanner says the test "isn't allowed", that is because minimum throttle hasn't been relearned yet.
