You can't bypass that sensor you need that sensor for the ECU to pick the correct map for the amount of throttle you are applying...

Check the voltage on it...There are 3 wires, one is ground and one is the output...Figure out which one is what...Use a voltmeter and measure the sensor so you see .48volts or so when the throttle is closed and 4.8 or so when the throttle is wide open, if you don't get similar readings, then you have to adjust the sensor's alignment till you get that reading...
