DTC P2108 DETECTION CONDITION AND POSSIBLE CAUSES

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.
POSSIBLE CAUSE	TP sensor No. 1 malfunction TP sensor No. 2 malfunction Connector or terminal malfunction Open circuit between throttle body terminal A and PCM terminal 2AK Short to ground between throttle body terminal A and PCM terminal 2AK Open circuit between throttle body terminal B and PCM terminal 2AO Open circuit between throttle body terminal D and PCM terminal 2AP Short to constant voltage supply between throttle body terminal A and PCM terminal 2AK Short to constant voltage supply between throttle body terminal C and PCM terminal 2AL PCM malfunction

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.

POSSIBLE CAUSE
