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)

This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction conditions during first drive cycle or in two consecutive drive cycles. PENDING CODE is available if PCM detects malfunction condition. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
