Error Code P2102: What It Means & What To Do?
OBD Code P2102 - Throttle Actuator A Control Motor Circuit Low
Is the engine stalling
and not starting? Are you experiencing sudden drop in acceleration with
inappropriate throttle response? All these can be an indication towards
problematic throttle actuator control motor, which may lead to OBD code P2102
getting stored in the Powertrain Control Module.
OBD code P2102 means
Throttle Actuator “A” Control Motor Circuit Low.
Learn More About OBD Error Code P2102
The opening and closing of the throttle plate is controlled by the throttle motor which increases or decreases the air flow to adapt and respond to the driver’s needs during acceleration. If the PCM detects that the throttle motor is not functioning properly for the throttle actuator “A”, it will store OBD code P2102 in the system and flash the Check Engine Light on the dashboard.
What causes this problem with the Throttle Actuator A Control Motor Circuit Low?
- Leakage in the vacuum
- Faulty manifold absolute pressure (MAP) sensor
- Malfunctioning mass air flow (MAF) sensor
- There can be inoperative exhaust gas recirculation (EGR) valve
- The vacuum hoses connected to the intake manifold might be damaged
- Some issues related to the short to power or ground in the 5 volt reference circuit
- Unusable vacuum brake booster
- Imperfect PCM
- There can be distorted electronic throttle control system (ETCS) / throttle body
- Defective throttle position sensor (TPS)
- Quirks in the throttle valve actuator
- The throttle valve might not be functioning properly
Replace/Repair These Parts To Fix Code P2102
- Engine Control
Module -
If there is any corrosion or breaks in the internal wiring of the harness, then
it can cause a short in the ECM or can also cause corrosion in the ECM through
the wiring harness. You can always rely on us as we have best auto parts
for our customers.
- Throttle
Position Sensor - Is
there a sudden bucking as well as jerking in your automobile. Then in that case
there is surely some fault in the throttle position sensor. Buy top notch throttle
position sensor from us at economical prices.
- Powertrain Control
Module -
The onboard computer, or powertrain control module is the brain of the engine
control system. Now if the brain is not working properly, then neither is the
car engine. Get it replaced before the situation gets worse.
- Pedal
Position Sensor - The
accelerator pedal position sensor is fixed to the accelerator pedal and it can
sense what position the pedal is in. A change in the position of the pedal
would lead the sensor to change the electric voltage which it supplies. So if
there are some faults in your pedal position sensor, then replace it soon!
- Electronic Control
Unit - Is your car jump starting on
reverse polarity? Or are you facing some intermittent starting issues? If yes,
then it indicates that your electronic control unit is bad. So it is very
important to replace the defective electronic control unit with us at equitable
prices.

Easy Diagnosis Of Engine Error OBD Code P2102
If you want to easily diagnose this P2102 fault code, then all you have to do is to follow the steps which are mentioned below:
- 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 throttle position sensor 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 continuity test between the PCM and solenoid to check the resistance.
- If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
- On test driving, if the P2102 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.
- If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
- 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 P2102 Code
- Malfunctioning mass air flow (MAF) sensor
- There can be a failure in the Throttle control motor
- Wiring problems
- There might be a leakage in the vacuum hose
- Defects in the accelerator pedal position (APP) assembly
- Flaws in the powertrain control module
