Detection Condition

DTC P0121 indicates a non-closed throttle position at idle.

DTC P0122 indicates Throttle Position (TP) sensor signal is less than self-test minimum of 0.17 volts (3.42 percent).

DTC P0123 indicates TP sensor signal is more than self-test maximum value of 4.65 volts (93 percent).

DTC P1120 indicates TP sensor signal is between 0.17-0.49 volts (3.42 and 9.85 percent).

DTC P1121 indicates TP sensor signal is inconsistent with Mass Airflow (MAF) sensor.

DTC P1124 indicates TP sensor rotational setting and signal are not in the self-test range of 0.66-1.17 volts (13.27-23.52 percent).

DTC P1125 indicates TP sensor signal went less than 0.49 volts or more than 4.65 volts during the last 80 warm-up cycles.

TP sensor is a linear type sensor. The PCM determines 4 throttle operating conditions from the TP sensor signal; closed throttle (idle or deceleration), part throttle (cruise or moderate acceleration), wide open throttle (maximum acceleration or de-choke on crank) and throttle angle rate.
