DTC P2108

Throttle actuator control module performance problem

DETECTION CONDITION

PCM detects either following conditions, PCM determines that throttle actuator control system has 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 continues monitor (CCM).
MIL illuminates if PCM detects the above malfunction condition during first drive cycle.
PENDING CODE is available if PCM detects the above malfunction condition.
FREEZE FRAME DATA is available.
DTC is stored in PCM memory.
