P2102 2015 Toyota RAV4 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 2015 Toyota RAV4 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 2015 Toyota RAV4?
- 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)

Frequently Asked Questions about P2102 2015 Toyota RAV4 Code
1. What does the OBDII code P2102 mean on a 2015 Toyota RAV4?
P2102 indicates a "Throttle Actuator Control Motor Circuit Low," meaning the vehicle's ECM has detected an issue with the throttle actuator control motor circuit receiving insufficient voltage.
2. What are the common symptoms of the P2102 code on a 2015 Toyota RAV4?
Symptoms may include reduced engine power (limp mode), an illuminated check engine light, poor acceleration, and unresponsive throttle.
3. What causes the P2102 code on a 2015 Toyota RAV4?
Common causes include a faulty throttle actuator motor, damaged or corroded wiring/connectors in the throttle actuator circuit, a malfunctioning ECM, or a blown fuse.
4. Can I still drive my 2015 Toyota RAV4 with the P2102 code?
Driving is not recommended as the vehicle may enter limp mode, limiting power and potentially causing unsafe driving conditions.
5. How do I diagnose the P2102 code on my 2015 Toyota RAV4?
Start by inspecting the throttle actuator wiring and connectors for damage or corrosion. Then, check the throttle actuator motor, fuses, and test for proper voltage in the circuit.
6. How do I fix the P2102 code on a 2015 Toyota RAV4?
Repairs may include replacing the throttle actuator control motor, repairing damaged wiring or connectors, replacing a blown fuse, or reprogramming/updating the ECM if necessary.
7. Can a dirty throttle body cause the P2102 code?
A dirty throttle body is unlikely to directly cause this code, but it can affect throttle performance. Cleaning the throttle body should still be part of routine maintenance.
8. How much does it cost to repair the P2102 code on a 2015 Toyota RAV4?
Costs vary depending on the issue, but throttle body motor replacement can range from $300 to $600, while wiring repairs may be less expensive.
9. Do I need to reset the ECM after fixing the P2102 code?
Yes, after repairs, clear the code with an OBDII scanner to reset the ECM and verify if the issue is resolved.
10. Can a weak battery trigger the P2102 code on a 2015 Toyota RAV4?
Yes, a weak or failing battery can result in low voltage to the throttle actuator circuit, potentially triggering the P2102 code.
