P2102 2018 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 2018 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 2018 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 2018 Toyota RAV4 Code
1. What does the OBDII code P2102 mean on a 2018 Toyota RAV4?
P2102 indicates a "Throttle Actuator Control Motor Circuit Low," meaning the throttle actuator motor is not receiving the correct voltage or signal from the engine control module (ECM).
2. What are the common symptoms of a P2102 code on a Toyota RAV4?
Symptoms may include reduced engine power, poor acceleration, the engine going into "limp mode," or the check engine light being illuminated.
3. What causes the P2102 code to appear on a 2018 Toyota RAV4?
Causes can include a faulty throttle actuator motor, damaged wiring or connectors in the throttle control circuit, a malfunctioning ECM, or low voltage from the battery.
4. Can I drive my 2018 Toyota RAV4 with a P2102 code?
Driving with a P2102 code is not recommended, as it can lead to reduced engine performance and potential safety issues due to limited acceleration.
5. How do I diagnose the P2102 code on my Toyota RAV4?
Diagnose by checking the throttle actuator motor, inspecting the wiring and connectors for damage, testing the voltage at the throttle control circuit, and verifying the ECM functionality.
6. How much does it cost to repair a P2102 code on a 2018 Toyota RAV4?
Repair costs vary but may range from $100 to $600 depending on whether the issue involves replacing the throttle actuator motor, repairing wiring, or reprogramming the ECM.
7. Can a weak battery cause the P2102 code on a Toyota RAV4?
Yes, a weak or failing battery can cause low voltage in the throttle control circuit, potentially triggering the P2102 code.
8. How do I reset the P2102 code after fixing the issue?
After repairs, you can reset the code using an OBDII scanner, or the ECM may clear it automatically after several drive cycles if the issue is resolved.
9. Is the P2102 code a common issue for the 2018 Toyota RAV4?
The P2102 code is not extremely common but can occur if there are issues with the throttle control system or electrical connections.
10. Can cleaning the throttle body fix the P2102 code on a Toyota RAV4?
While cleaning the throttle body may help with some throttle-related issues, P2102 typically points to an electrical problem, so cleaning alone may not resolve the code.
