Detection Condition
If PCM detects either of following conditions, PCM determines throttle actuator control system has malfunction.
- TP sensor power supply voltage less than 4.4 volts
- TP sensor No. 1 output voltage less than 0.20 volt or more than 4.85 volts (DTC P0122 or P0123)
- TP sensor No. 2 output voltage less than 0.20 volt or more than 4.85 volts (DTC P0222 or P0223)
- PCM internal circuit for TP sensor No. 1 input circuit malfunction
- Wrong communication between main CPU and throttle control system (CPU is an internal part of PCM)
