DTC P2108:00: Notes

DTC P2108:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES

DTC P2108:00 Throttle valve actuator control module performance problem
DETECTION CONDITION 
  • If the PCM detects either of the following conditions, the PCM determines that the throttle valve actuator control system has a malfunction.
    • TP sensor power supply voltage: below 4.40 V 
    • TP sensor No. 1 output voltage: below 0.20 V or above 4.85 V  (DTC P0122:00 or P0123:00)
    • TP sensor No. 2 output voltage: below 0.20 V or above 4.85 V  (DTC P0222:00 or P0223:00)
    • PCM internal circuit for TP sensor No. 1 input circuit malfunction
    • PCM internal malfunction

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • Throttle body connector or terminals malfunction
  • Short to ground in wiring harness between the following terminals:
    • Throttle body terminal B-PCM terminal 2AO
    • Throttle body terminal A-PCM terminal 2AK
    • Throttle body terminal C-PCM terminal 2AL
  • Short to power supply in wiring harness between the following terminals:
    • Throttle body terminal A-PCM terminal 2AK
    • Throttle body terminal C-PCM terminal 2AL
  • Open circuit in wiring harness between the following terminals:
    • Throttle body terminal B-PCM terminal 2AO
    • Throttle body terminal A-PCM terminal 2AK
    • Throttle body terminal D-PCM terminal 2AJ
  • TP sensor No. 1 and/or No. 2 malfunction
  • PCM malfunction
