Detection Condition
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
- 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 volt (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 falls between 0.17 and 0.49 volt (3.42 and 9.85 percent).
- DTC P1121 indicates TP sensor signal is inconsistent with Mass Airflow/Intake Air Temperature (MAF/IAT) sensor.
- DTC P1124 indicates TP sensor rotational setting and signal are not in 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 volt 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).
- Throttle angle rate.
- Wide open throttle (maximum acceleration or de-choke on crank).
