P2119 2004 Toyota Highlander Code - Throttle Actuator Control Throttle Body Range/Performance
Quick Answer
The Electric Throttle Control System (ETCS) is composed of the throttle motor to operate the throttle valve, the electromagnetic clutch to connect the throttle motor with the throttle valve, the throttle position sensor to detect the opening angle of the throttle valve, the accelerator pedal position sensor to detect the accelerator pedal position, the ECM to control the ETCS and the one valve type throttle body. Common causes include Faulty electric throttle control actuator, Throttle plate sticking due to carbon build-up, Electric throttle control actuator harness is open or shorted. 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 P2119 2004 Toyota Highlander Description
The ECM controls the throttle motor to make the throttle valve opening angle properly in response driving condition.
The throttle position sensor which is mounted on the throttle body detects the opening angle of the throttle valve, and it provides feedback to the ECM to control the throttle motor.
If the ETCS has a malfunction, the ECM shuts down the power for the throttle motor and the magnetic clutch, and the throttle valve is fully closed by the return spring.
However, the opening angle of the throttle valve can be controlled by the accelerator pedal through the throttle cable.
What are the Possible Causes of the DTC P2119 2004 Toyota Highlander?
- Faulty electric throttle control actuator
- Throttle plate sticking due to carbon build-up
- Electric throttle control actuator harness is open or shorted
- Electric throttle control actuator poor electrical circuit connection
- Engine Control Module

2. What are common symptoms of the P2119 code in a 2004 Toyota Highlander?
Symptoms may include reduced engine power, poor acceleration, the vehicle entering "limp mode," rough idling, or the Check Engine Light being illuminated.
3. What causes the P2119 code to appear in a Toyota Highlander?
Potential causes include a dirty or malfunctioning throttle body, a damaged throttle position sensor, a faulty throttle actuator motor, wiring issues, or a problem with the engine control module (ECM).
4. Can a dirty throttle body trigger the P2119 code?
Yes, a dirty or carbon-clogged throttle body can cause the throttle plate to stick or not move properly, which can trigger the P2119 code.
5. How do you diagnose the P2119 code on a 2004 Toyota Highlander?
Diagnosis typically involves scanning for codes, inspecting the throttle body for dirt or damage, testing the throttle actuator motor and position sensor, and checking for wiring issues in the TAC system.
6. Can I drive my 2004 Toyota Highlander with the P2119 code?
Driving with the P2119 code is not recommended, as the vehicle may enter limp mode, limiting power and potentially leading to unsafe driving conditions.
7. How is the P2119 code fixed in a 2004 Toyota Highlander?
Repairs may include cleaning or replacing the throttle body, repairing or replacing damaged wiring, testing and replacing the throttle actuator motor, or reprogramming or replacing the ECM.
8. Will clearing the code fix the P2119 issue permanently?
Clearing the code may temporarily turn off the Check Engine Light, but the underlying issue must be addressed to prevent the code from returning.
9. How much does it cost to repair the P2119 code on a Toyota Highlander?
Repair costs vary but may range from $100 to $600 depending on whether the throttle body needs cleaning, repair, or replacement, as well as labor costs.
10. Can a faulty throttle position sensor cause the P2119 code?
Yes, a malfunctioning throttle position sensor can send incorrect signals to the ECM, leading to the P2119 code.
