Better get a mechanic to check the circuit going to the tps, as they give some problems! Just fixed a Tiburon, same engine and it was the computer!
This is not to say that is your trouble, however the customer had three sensors installed before having it really checked. Code scanners dont actually tell you what the problem is, needs more test.
