What is P2102 : Engine Error code Causes Explained
This guide covers the P2102 engine error code, its meaning, causes, and solutions. Low throttle actuator control motor circuitry may decrease throttle responsiveness and engine performance.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P2102 refers to a throttle actuator control motor circuit low issue. To identify a DTC’s number like P2102, you need an OBD-II scanner, which can be plugged into the vehicle’s diagnostic port, usually located beneath the dashboard.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
Once connected, the scanner will read the trouble codes stored in the ECM and display them on the screen.
Causes of P2102 Error Code:
- Faulty Throttle Actuator:
The throttle body motor, which controls air intake, is likely malfunctioning. - Damaged Wiring Harness:
Damaged throttle actuator wiring can send a low signal to the PCM. - Defective Throttle Position Sensor:
A faulty throttle position sensor can trigger the code. - Dirty Throttle Body:
Dirt buildup on the throttle plate can cause the code. - Faulty PCM:
In rare cases, a faulty Powertrain Control Module could be causing the issue.
Risk Level of P2102 Error Code:
A high-risk level appears when the vehicle’s ECU detects a persistent or critical failure in the throttle control system, which can compromise drivability and safety.
When facing a P2102 code along with by a “High Risk Level” warning, it’s essential to take immediate action.
Common Car Brands Affected by P2102 Code:
The P2102 engine error code is commonly found in the following list.
- Ford
- Nissan
- Toyota

FAQ’s
What is the P2102 Error Code?
P2102 indicates a problem with the throttle actuator control motor circuit, often due to low voltage or a malfunctioning throttle body.
What Causes the P2102 Error?
Common causes include a faulty throttle actuator motor, wiring issues, a defective throttle body, or a failing engine control module (ECM).
What is the Risk Level of This Code?
The risk level is high as it can cause throttle response failure, reduced engine power, or even prevent the vehicle from accelerating properly.
Which Vehicles Are Affected?
This code commonly affects modern vehicles with electronic throttle control systems, including models from Ford, Nissan and Toyota.
