* At idle throttle blade is 10° open. When throttle is opened from idle to wide open throttle, the blade has traveled only 80°.
** The Powertrain Control Module (PCM) considers an increase of 1.80 volts or more wide open throttle.
*** The PCM will shut off fuel injection if Throttle Position Sensor (TPS) voltage is 2.43 V above minimum.
