P2102 Scion Code - Throttle Actuator Control Motor Circuit Low
Quick Answer
The Throttle Actuator is operated by the Engine Control Module (ECM) and opens and closes the throttle valve using gears. Common causes include Dirty throttle body, Faulty Throttle Actuator, Throttle Actuator harness is open. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2102 Scion Description
The opening angle of the throttle valve is detected by the throttle position sensor, which is mounted on the throttle with motor body assembly. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.
The ECM monitors the electrical current through the electronic actuator and detects malfunctions and open circuits in the throttle actuator based on this value. If the current is outside the standard range, the ECM determines that there is a malfunction in the throttle actuator. In addition, if the throttle valve does not function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM then illuminates the MIL and stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P2102 Scion?
- Dirty throttle body
- Faulty Throttle Actuator
- Throttle Actuator harness is open
- Throttle Actuator circuit poor electrical connection
- Faulty Throttle with Motor Body Assembly
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2102 Scion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2102 Scion code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P2102 Scion Code
What does the OBDII code P2102 mean for a Scion?
P2102 indicates that the throttle actuator control (TAC) motor circuit is experiencing low voltage, which may affect the throttle's ability to open and close properly.
What are the common symptoms of the P2102 code in a Scion?
Symptoms may include reduced engine performance, the vehicle going into limp mode, poor throttle response, or the check engine light being illuminated.
What causes the P2102 code to appear in a Scion?
Common causes include a faulty throttle actuator motor, damaged wiring or connectors in the TAC circuit, a malfunctioning throttle body, or issues with the powertrain control module (PCM).
Can I drive my Scion with the P2102 code active?
Driving with the P2102 code is not recommended as it may lead to reduced performance, unsafe driving conditions, or further damage to the throttle system.
How do I diagnose the P2102 code in a Scion?
Diagnosis involves inspecting the throttle actuator motor, checking the wiring and connectors for damage or corrosion, and testing the voltage and continuity in the TAC circuit.
What tools are needed to diagnose and fix the P2102 code?
You’ll need an OBDII scanner, a multimeter, basic hand tools, and possibly a wiring diagram for your Scion to properly diagnose and repair the issue.
How much does it cost to repair the P2102 code on a Scion?
Repair costs can range from $100 to $500, depending on whether the issue is a simple wiring repair or requires replacing the throttle body or actuator motor.
Can a dirty throttle body cause the P2102 code in a Scion?
While a dirty throttle body is not a direct cause, it can lead to throttle actuator strain, which might contribute to the failure of the TAC motor or related components.
Does the P2102 code always mean the throttle actuator motor is bad?
No, the issue could also be caused by wiring problems, connector issues, or a fault in the PCM, so a thorough diagnosis is necessary.
How can I prevent the P2102 code from occurring in the future?
Regular maintenance, including cleaning the throttle body and inspecting wiring and connectors, can help prevent issues that trigger the P2102 code.
