DTC P2108

Throttle actuator control module performance problem

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.

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 3M
• Short to ground between throttle body terminal A and PCM terminal 3M
• Open circuit between throttle body terminal B and PCM terminal 3P
• Open circuit between throttle body terminal D and PCM terminal 3Q
• Short to the constant voltage supply between throttle body terminal A and PCM terminal 3M
• Short to the constant voltage supply between throttle body terminal C and PCM terminal 3J
• PCM malfunction

Yes
Go to the next step.
No
Replace the throttle body, then go to nest step.
7
VERIFY TROUBLESHOOTING OF DTC P2108 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Turn ignition switch to the ON position (Engine off).
• Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
8
