Code P2102 Scion Description
The P2102 diagnostic trouble code for Scion vehicles indicates a problem with the throttle actuator control motor circuit being lower than the expected range. The throttle actuator control motor is responsible for controlling the opening and closing of the throttle valve, which regulates the airflow into the engine. When this circuit is detected to be low, it means that there is a potential issue with the motor's ability to function properly, which can have significant implications for the vehicle's performance.
Common Causes of P2102 Scion
- Faulty throttle actuator control motor
- Wiring issues or loose connections
- Faulty throttle position sensor
- Electronic control module malfunction
- Corrosion or damage to electrical components
Symptoms of P2102 Scion
- Rough idling
- Poor acceleration
- Stalling
- Reduced fuel efficiency
- Limp mode activation
How to Fix P2102 Scion
- Perform a comprehensive diagnostic scan to confirm the P2102 code and identify the specific cause of the issue.
- Inspect the throttle actuator control motor, wiring, and connections for any signs of damage or malfunction.
- Test the throttle position sensor to ensure it is functioning correctly.
- Replace any faulty components, such as the throttle actuator control motor, throttle position sensor, or wiring harness.
- Clear the diagnostic trouble codes, reset the engine control module, and perform a test drive to verify that the issue has been resolved.
Cost to Fix P2102 Scion
The typical repair costs for addressing a P2102 code on a Scion vehicle can range from $200 to $500, depending on the specific cause of the issue and the cost of replacement parts.

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.
