On the off chance that I'm stating the obvious:
The Throttle Position Sensor measures throttle position.
arn: It's just a sensor (usually ~zero to ~5VDC). Most cars, it needs to measure linearly, that is, 20% of its movement should change the voltage by 20%. (On some makes, a bad sensor no longer reads that way so it causes driveability issues.)It's the ECU that interprets the signal and makes the engine run a certain way based on what it is 'seeing'. Remember too, that there are other inputs to the ECU, like ambient air temp, coolant/cylinder head temp, etc. It's a SYSTEM.

Regards your other question: Honda only sells the entire throttle body containing the TPS sensor for the Gen2, and they rivet it in for good measure. :beb: Aftermarket DOES sell just the TPS.
