2006 CR-V EX, 5MT
On the off chance that I'm stating the obvious:what's the "throttle position" measuring, anyone know? is it the "APP" sensor the throttle cable connects to on the firewall, or is it the actual sensor/motor down on the throttle body?
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.
