P2107 OBD Error Code: Problem & Solutions
OBD Code P2107 - Throttle Actuator Control Module Processor
An
increase in the fuel consumption and the engine performance along with
occasional engine stalling and with improper throttle response and acceleration
may be an indication of problem with the throttle control system hampering the
vehicle’s performance, thus indicating OBD Code P2107.
OBD
code P2107 refers to Throttle Actuator Control Module Processor Issue
Learn More About OBD Error Code P2107
There is no mechanical linkage between the accelerator pedal and the throttle valve with electronic throttle control. Instead, the position of the throttle valve is fully controlled by the ETC software via the electric motor. But just opening or closing the throttle valve by sending a new signal to the electric motor is an open loop condition and leads to inaccurate control. Thus, most if not all current ETC systems use closed loop feedback systems, such as PID control, whereby the ECU tells the throttle to open or close a certain amount. The throttle position sensors are continually read and then the software makes appropriate adjustments to reach the desired amount of engine power.
If the PCM detects that the throttle actuator control module processor has malfunctioned, the OBD code P2107 gets stored in the system, illuminating the malfunction indicator light.
What causes this problem with the Throttle Actuator Control Module Processor?
- Accelerator pedal position sensor problematic
- Throttle position sensor faulty
- Wiring and connector problem
- Throttle plate dirty
- Poor electrical connections
Replace/Repair These Parts To Fix Code P2107
- Powertrain Control
Module – Faulty PCM should be
repaired, replaced and reprogrammed as it can cause a lot of problems in the
vehicle by affecting the engine performance along with the transmission, fuel
delivery and exhaust systems.
- Diagnostic
Tool – Make use of quality diagnostic tools to
resolve any OBD error code. Buy quality diagnostic tools from us!
- Throttle Position
Sensor – A throttle position sensor
(TPS) is a sensor used to monitor the throttle position of a vehicle. The
sensor is usually located on the butterfly spindle/shaft so that it can
directly monitor the position of the throttle. Thus, replace faulty TPS now!
- Throttle Actuator
Connector – Damaged or corroded
connectors will affect the functioning of the throttle control system and thus
the working of the throttle plates, hampering the vehicle performance. Replace
faulty connectors immediately.
- Throttle Control
Relay – The power supply for the
throttle control provides the PCM (powertrain control module, also known as ECM
or engine control module) through throttle control motor relay. The latter is
turned On/Off by the former; when the ignition is switched off, the PCM will
send a signal to the throttle control motor relay and a battery voltage is
provided to the PCM. When the ignition is switched off, the PCM will send an
off signal to the throttle control motor relay and battery voltage will not be
provided by the PCM. Thus, replace faulty throttle control relay immediately.
- Accelerator Pedal
Sensor – When you press down on the
gas pedal, your engine should respond directly and instantly. However, when a
problem with the APP sensor exists, the vehicle's ability to consistently
accelerate or decelerate as directed by the driver will be reduced. This could
cause a serious safety situation as essentially the driver is not in control of
the vehicle. When this occurs, you should pull your vehicle to a safe place off
the road and contact a mechanic as soon as possible to inspect the reason why
throttle control is not consistent. Thus, replace faulty APP sensor now!

Easy Diagnosis Of Engine Error OBD Code P2107
It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2107 code to be stored:
- The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
- After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
- Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
- The mechanic performs a test for the problems in the accelerator pedal sensor, throttle position sensor and the throttle control system.
- If the above mentioned components are not faulty, he will then retune the code and test drive the vehicle.
- On test driving, if the P2107 code does not return soon, he will know that an erratic condition exits.
- But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc. for any possible fault.
- If any component is damaged, he will fix them right away.
- After performing this repair, he will inspect the throttle position sensor as well as its wiring and connectors.
- Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.
Common Mistakes When Diagnosing the P2107 Code
- PCM and ECU failure
- Wiring and connectors damaged, broken or short
- Accelerator pedal position sensor problematic
- Throttle position sensor failure
