blinks paused then 11 blinks. I read a
code 41 is for the TPS. But like i said

See if you can get a repair manual for your Toyota that lists the OBD I trouble codes. I'm not familiar with them but you could be seeing a reference code to let you know you entered diagnosis mode. On GM OBD I systems, for example, you get a reference code 12. Then the trouble codes start flashing out. HTH. -Jim
