DETECTION CONDITION 
  • If the PCM detects either of the following conditions, the PCM determines that throttle actuator control system has a malfunction.
    • TP sensor power supply voltage below 4.4 V 
    • TP sensor No. 1 output voltage below 0.20 V or above 4.85 V  (DTC P0122 or P0123)
    • TP sensor No. 2 output voltage below 0.20 V or above 4.85 V  (DTC P0222 or P0223)
    • PCM internal circuit for TP sensor No. 1 input circuit malfunction.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA is available.
  • DTCs are stored in PCM memory.
