Throttle Position Sensor Monitor - P0121 - P0123, P0222, P0223

Throttle position sensor monitor - P0121 - P0123, P0222, P0223
During ignition on conditions the voltages from the two-track throttle position sensor are monitored. If the input voltage stays above a calibratable value for more than a calibratable period, the high input failure judgement is made. If the input voltage stays below a calibratable value for more than a calibratable period, the low input failure judgement is made. If the angle obtained from sensor 1 differs from the angle obtained from sensor 2 by more than a calibratable amount for more than a calibratable period a range / performance failure judgement is made.
