Answer
Hi Ed,
 Try resetting the ECU. The best way is have a shop hook up
a scanner and clear it. Most shops will charge for this, I wouldn't.
Otherwise you can reset the ECU by disconnecting the negative clamp on the battery for 5 minutes. DON'T do this until you read your
owners manual in the glove box on the procedure or talk to a COMPETENT Toyota dealership service rep. The reason is some stereos
and alarm systems will be affected and won't work until you set the
code back in them.(you will have to get the code from a dealership
if you don't have it).
Good luck, let me know.
