Error Code P2106: What It Means & What To Do?
OBD Code P2106 - Throttle Actuator Control System - Forced Limited Power
Is your vehicle engine performance decreasing and
limited throttle response? Do you notice the Malfunction Indicator Light
illuminated on the dashboard? If there are faults in the throttle control
system of the car, especially the fuel injector, then P2106 fault code is
definitely going to trigger up.
Learn More About OBD Error Code P2106
The throttle body assembly contains two throttle position sensors that work with the PCM to control the throttle response. As the voltage signal from the sensor 2 increases, the throttle opens and similarly, as the voltage in sensor 1 decreases, the throttle opens. If this reference voltage is out of bounds, the PCM stores OBD code P2106 in the system and the vehicle goes into “fail safe” mode.
What causes this problem with the Throttle Actuator Control System - Forced Limited Power?
- There might be some problems related to engine misfires
- The throttle position sensors might start giving incorrect readings
- Possible coolant leakage
- Less fuel pressure or the fuel might not be enough
- Malfunctioning PCM
- There can be inoperative MAF sensor
Replace/Repair These Parts To Fix Code P2106
- Powertrain Control
Module – P2106 code can display due to
some issues in the Powertrain Control Module. Faulty PCM can lead to engine
stalling and vehicle going into fail safe mode. Thus the PCM might need to be
repaired, replaced or reprogrammed, if required.
- Diagnostic
Tool – Usually any OBD code problem requires
deep insight into the problem and high grade tools in order to fix it properly.
Thus, buy quality diagnostic tools from us!
- Throttle Position
Sensor – The TPS informs the PCM about
the reference voltage which further helps in decision making for the opening
and closing of the throttle valve and plate. Thus, replace faulty TPS now!
- Throttle Actuator
Connector – The connectors act as
bridges between the circuit and the components. If the connectors are damaged,
or broken, they must be replaced immediately. This is a much cheaper solution
to any OBD problem and thus replace it now!
- Throttle Control
Relay – If the throttle control relay
is damaged, it will lead to major performance issues and can also pose danger
to the driver due to irregular throttle response. Thus, it is important to
replace faulty relay. Buy new throttle control relay from us now!
- Accelerator Pedal
Sensor – If the throttle control
system is unable to interpret the data from the accelerator pedal sensor, the
PCM will be unable to respond to the power demand, thus posing performance
issues. Thus, check for faults in the pedal sensor and replace it now!

Easy Diagnosis Of Engine Error OBD Code P2106
Here are some steps which you should follow in order to diagnose this P2106 fault code:
- Make use of an OBD-II scanner (or code reader) and a digital volt/ohmmeter to successfully diagnose this error code.
- Visually inspect all wiring and connectors in association with the throttle position sensor and the accelerator pedal sensor respectively. Next, repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components.
- It is advisable to retest the system after repairs are completed to ensure success. If all system wiring, connectors, and components (Including fuses) appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored codes and freeze frame data. Continue to clear the code and operate the vehicle to see if the code returns. You may have an intermittent condition, if the code fails to return.
- Voltage and ground signals are tested at the throttle actuator control motor connector, when the motor is activated using the scanner. Disconnect the connector from the PCM and all related controllers and test individual circuits for resistance and continuity, if the voltage and ground signals are not present.
- Repair or replace open, shorted, or disconnected circuits as required and clear the codes to test drive the vehicle to ensure a successful repair.
- Replace the motor, if the ground signal and voltage is present at the throttle actuator motor connector. Most likely, you might need to replace the entire throttle body, which includes the actuator motor, pedal sensor and the throttle position sensor.
- Use a specialized diagnostic CAN scanner to check the pin values and control module operation without risking a meltdown. It will aid in diagnosing the computer and circuitry problems by monitoring vehicle operation while the vehicle is still in operation.
Common Mistakes When Diagnosing the P2106 Code
Mistakes can easily be made by anyone if they skip steps or do not complete all steps required. These steps should always be followed to avoid unnecessary repairs, and save time and money.
- Wiring and connector problems
- TPS problems
- Accelerator pedal position sensor problems
- PCM problematic
