Guide To P2100 OBD Error Code Solutions
OBD Code P2100 - Throttle Actuator A Control Motor Circuit Open
Is
the vehicle’s Check Engine Light illuminating on the dashboard? Are you
experiencing poor throttle response with engine stalling and hesitating? Is
there a visible effect on the vehicle’s fuel economy? All these are direct
indications of a problematic throttle actuator which may lead to OBD code P2100
getting stored in the Powertrain Control Module, which may even lead to the
vehicle going into fail safe mode.

The Accelerator Pedal Position Sensor (APP) informs the Powertrain Control Module about the power requested by the vehicle. This information is then passed on to the Electronic Throttle Control System (ETCS) which controls the valve opening. If the PCM detects that the throttle place is not opening properly and the motor circuit is open, it will set OBD code P2100 in the system.
What causes this problem with the Throttle Actuator A Control Motor Circuit Open?
- Throttle actuator circuit open
- Throttle control system failure
- Accelerator Pedal Position Sensor faulty
- PCM faults
- Wiring and connector issues
Replace/Repair These Parts To Fix Code P2100
- Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
- Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus check and replace it, if required.
- Diagnostic Tools – It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!
- Throttle Position Sensor – Faulty throttle position sensor can cause bucking and jerking in the vehicle. It may also cause sudden idle surges and engine stalling without any reason. Thus, replace faulty throttle position sensor now!
- Throttle Actuator Connector – If the throttle actuator connector is faulty, it may result in the throttle pedal not opening in time and causing improper throttle response and sluggish acceleration. Thus, replace it now!
- Throttle Control Relay – The throttle control relay can also be faulty, leading to poor throttle response and rough idles. It may also lead to hesitations during acceleration and deceleration. Thus, replace faulty throttle control relay and buy a new one from us!
- Accelerator Pedal Sensor – The accelerator pedal sensor is used to transmit information to the throttle control system to control the opening and closing of the throttle plates. If the pedal sensor is faulty, the PCM will not be able to interpret the driver’s demand, thus hampering the throttle response. So, replace faulty sensor now!

Easy Diagnosis Of Engine Error OBD Code P2100
Here are some steps which you should follow in order to diagnose this P2100 fault code:
- First, check for technical service bulletins (TSB) for the particular make and model of the vehicle. This issue may be a known issue with a known fix put out by the manufacturer and can save time and money during diagnosis.
- Next, locate the Throttle Actuator A (TA-A). This actuator is usually found mounted to the front of the engine, on top of the engine, inside the wheel wells or against the bulkhead.
- Visually inspect the connector and wiring for scraping, rubbing, bare wires, burn spots or melted plastic. Check the connector terminals carefully for burned or green tint indicating corrosion.
- Use a scan tool, to clear the diagnostic trouble codes from memory, and see if P2100 code returns. If it does not, then the connections were most likely your problem.
- Test the actuator and the related circuits. Check for the resistance specifications for particular make and model. If the actuator motor is either open or shorted, replace the Throttle Actuator.
- With the help of a DVOM, make sure of 12V to the Throttle Actuator power supply circuit.
- Check for faulty PCM and repair and reprogram it, if necessary.
Common Mistakes When Diagnosing the P2100 Code
- Not clearing ECM codes after fixing the problem
- Not checking the wiring and connectors properly
- PCM faults and system failures
