I think the TPS is pretty important as it sends information to the ECU, but before you spend money to get it replaced, verify that it is broken first. just disconnect the wire harness and test pins 1 & 3. The correct voltage across these two pins with the key in on position but engine off should be between 535--735 mV. Also check that the TPS is working by measuring the resistance again between pins 1 & 3 but on the TPS side on the TB. When pushing down on the connector to the end of the accellerator cable at the TB (hence opening up the butterfly valve inside), the change in metered resistance should change smoothly. Good luck.
Oh BTW, do not remove the TPS off the TB w/o first measuring what the original resistance is. Then when you replace the TPS, you can set it back to the original resistance. I had to do this when I swapped out my TB.
