You r screen name just hit me... so I presume you have a 1JZ. Might want to mention that or put it in your signature. The link I posted is from the Toyota Service and Repair Manual for the USDM MKIII which was never available with the 1JZ. For a 1JZ manual you'll do well to check the UK and AUS websites. A link has probably been posted here in the past, or you could also check the swaps section over at supramania.com.... I know it's been posted there.
TPS - Throttle Position Sensor, probably 99% of EFI equipped cars have them. They're always (well, almost) on the throttle body. And TPS is the standard acronym, nothing specific to Toyota.
