Common Causes of P2119 in Ford Fusion 2010
The P2119 trouble code in a 2010 Ford Fusion typically indicates a problem with the throttle actuator control system, specifically related to the throttle actuator control motor circuit. This fault code arises when the Engine Control Module (ECM) detects an issue with the throttle position or its control, which can lead to reduced engine performance or even a limp mode condition.
Several common factors can trigger the P2119 code:
- Faulty Throttle Body Assembly: Carbon buildup or mechanical wear can impair the throttle plate’s movement, causing the actuator motor to struggle in controlling throttle position.
- Wiring and Connector Issues: Damaged or corroded wiring harnesses and connectors between the ECM and throttle actuator motor can interrupt signal transmission.
- Throttle Position Sensor (TPS) Failure: A malfunctioning sensor may send incorrect position data to the ECM, leading to improper throttle control.
- ECM Software Glitches or Hardware Failures: Outdated software or internal ECM faults can misinterpret signals from the throttle actuator motor.
- Battery Voltage Problems: Low or unstable voltage supply can affect the throttle actuator motor’s operation.
Understanding these causes helps in narrowing down the root issue and determining the appropriate repair approach.
Diagnostic Steps for P2119 Code
Diagnosing the P2119 code involves a systematic approach to isolate the cause effectively. The following steps are essential:
- Visual Inspection: Check the throttle body for excessive carbon deposits or physical damage. Inspect wiring harnesses and connectors for signs of corrosion, fraying, or disconnections.
- Battery Voltage Check: Verify that the battery voltage is within specifications, as low voltage can cause erratic throttle actuator behavior.
- Scan Tool Analysis: Use an OBD-II scanner to monitor live data from the throttle position sensor and throttle actuator motor during engine operation.
- Electrical Testing: Measure resistance and continuity in the throttle actuator motor circuit using a multimeter.
- Throttle Body Cleaning: Remove carbon buildup that might be restricting throttle plate movement.
- ECM Software Update: Check for any available ECM updates or recalls related to throttle actuator control.
By following these diagnostics, technicians can pinpoint whether the issue lies in mechanical, electrical, or software components.
Repair and Replacement Guidelines
Once diagnostics identify the source of the P2119 code, the following repair strategies are recommended:
- Throttle Body Cleaning or Replacement: If carbon buildup is severe, cleaning may restore function; however, a damaged throttle body requires replacement.
- Wiring Repair: Replace or repair any damaged wiring or connectors to ensure proper communication between ECM and throttle actuator.
- Throttle Position Sensor Replacement: Swap out a faulty TPS to restore accurate throttle position feedback.
- ECM Reprogramming or Replacement: Update ECM software or replace the module if it is malfunctioning.
- Battery Service: Address any battery or charging system issues affecting voltage supply.
In many cases, addressing wiring and cleaning the throttle body resolves the issue without the need for costly component replacements.

Following these guidelines helps maintain optimal throttle system performance and reduces the likelihood of triggering the P2119 code.
Understanding the P2119 Code on a 2010 Ford Fusion
The diagnostic trouble code (DTC) P2119 on a 2010 Ford Fusion indicates an issue with the Electronic Throttle Control (ETC) system, specifically related to the throttle actuator control motor current being higher than expected. This code is generated when the Powertrain Control Module (PCM) detects an abnormal current draw in the throttle body’s electric motor, which controls the throttle plate’s position.
Causes of the P2119 Code
Several potential causes can trigger the P2119 code on a 2010 Ford Fusion:
- Faulty throttle body assembly: The throttle actuator motor or its internal components may be malfunctioning or worn out.
- Wiring issues: Damaged, corroded, or shorted wiring and connectors between the PCM and throttle body can cause abnormal current readings.
- PCM malfunction: The engine control module could be sending incorrect signals or misinterpreting sensor data.
- Foreign debris or carbon buildup: Obstruction or excessive carbon deposits on the throttle plate can cause the motor to draw excessive current while attempting to move.
- Electrical shorts: Internal shorts in the throttle actuator motor windings or related circuitry.
Symptoms Associated with P2119 on a 2010 Ford Fusion
Drivers may experience various symptoms when the P2119 code is present:
