DTC P2108: Notes

DTC P2108 [L3] CHART

DTC P2108	Throttle actuator control module performance error
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 DTC P0123) TP sensor No. 2 output voltage below 0.20 V or above 4.85 V (DTC P0222 or DTC 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 in the first drive cycle. FREEZE FRAME DATA is available. The DTC is stored in the PCM memory.

DTC P2108

Throttle actuator control module performance error

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 DTC P0123)
- TP sensor No. 2 output voltage below 0.20 V or above 4.85 V (DTC P0222 or DTC 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 in the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE
