WARNING: This page is about a different car, the 2003 Mazda B4000, 2003 Mazda B3000, and 2003 Mazda B2300. 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 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 is 0.17-0.49 volts (3.42 and 9.85 percent).
- DTC P1121 indicates TP sensor signal is inconsistent with 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 volt or more than 4.65 volts during the last 80 warm-up cycles.
Throttle Position (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.
