oh and i just thought of another thing, now don't quote me on this but i have heard that you can use a map sensor off any toyota as long as
1. its a toyota sensor
2. its a 5v sensor
3. its a 3 pin loom connector
so you might wanna try getting a map of a late gen 4age or 3sge engine and see how ya go even if the codes don't match 100%, i'm trying this this weekend i'll let ya know how it goes, but I think they are going to be universal coz you sensor code matches my sensor code from a 1G-E engine whilst you have a 4agze totally dif engines.
