Code P2102 2009 Toyota Camry Description
The P2102 diagnostic trouble code (DTC) for a 2009 Toyota Camry indicates a problem with the Throttle Actuator Control (TAC) motor circuit being lower than expected. The TAC system is responsible for controlling the throttle plate opening to regulate the airflow into the engine, which in turn affects the engine's performance. When the TAC motor circuit is low, it means that the signal voltage or current going to the throttle actuator motor is below the expected range, leading to potential issues with engine performance and drivability.
Common Causes of P2102 2009 Toyota Camry
- Faulty throttle actuator motor
- Wiring harness issues
- Faulty connectors
- Problems with the powertrain control module (PCM)
- Electrical issues such as short circuits or open circuits
Symptoms of P2102 2009 Toyota Camry
- Reduced acceleration
- Hesitation or stalling when accelerating
- Rough idling
- Illuminated check engine light
How to Fix P2102 2009 Toyota Camry
- Perform a thorough inspection of the throttle actuator motor, wiring harness, and connectors to identify any visible damage or issues.
- Test the throttle actuator motor and related components using a multimeter to check for proper voltage and continuity.
- Check the PCM for any fault codes related to the TAC system and perform necessary diagnostics to determine if the PCM is functioning correctly.
- Replace any faulty components such as the throttle actuator motor, wiring harness, connectors, or PCM as needed.
- Clear the DTC and perform a test drive to verify that the issue has been resolved and that the vehicle is operating properly.
Cost to Fix P2102 2009 Toyota Camry

Common symptoms include reduced engine power, the check engine light illuminating, erratic or unresponsive acceleration, and possible engine stalling.
What could cause the P2102 code to trigger in a 2009 Toyota Camry?
Causes may include a faulty throttle actuator, damaged wiring or connectors in the throttle control circuit, or issues with the engine control module (ECM).
How can I diagnose the P2102 code in my 2009 Toyota Camry?
To diagnose the code, start by visually inspecting the throttle actuator and related wiring for damage. Then, use a multimeter to test the voltage and resistance in the circuit, and check for any other stored trouble codes.
What are some common repair solutions for the P2102 code?
Common repairs include replacing a faulty throttle actuator, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if it's determined to be faulty.
Is it safe to drive with the P2102 code in my 2009 Toyota Camry?
Driving with the P2102 code is not recommended, as it can lead to reduced engine performance and potential safety issues due to unresponsive throttle control.
Can I clear the P2102 code by disconnecting the battery?
Disconnecting the battery may temporarily clear the code, but if the underlying issue is not fixed, the code will likely return once the vehicle is driven.
Will the P2102 code cause my 2009 Toyota Camry to fail emissions testing?
Yes, since the check engine light is likely to be on with this code, it can cause the vehicle to fail emissions testing until the issue is resolved and the code is cleared.
How much does it typically cost to fix the P2102 code on a 2009 Toyota Camry?
Repair costs can vary widely depending on the cause but may range from $100 for wiring repairs to over $500 for a throttle actuator replacement.
