P2119 OBD-II Trouble Code: Throttle Actuator Control Throttle Body Range/Performance

P2119 code definition

Throttle Actuator Control Throttle Body Range/Performance

What the P2119 code means

This code indicates that the throttle valve is not in the position the PCM (Powertrain Control Module) expects it to be in.

What causes the P2119 code?

Most often the cause of this code is either the TPS (Throttle Position Sensor) which is an integral part of the throttle body or the TPPS (Throttle Pedal Position Sensor) which is part of the throttle pedal assembly at your feet.

These components are part of the ETCS (Electronic Throttle Control System). Electronically controlled throttles found on most modern vehicles utilize PCM programming to set and monitor the throttle position. Because of the complicated nature of programming, the PCM will often set codes for what it believes to be the problem. There are many scenarios where this code can be set but the problem is not in the ETCS components. It is important to recognize other symptoms and or codes that will indirectly set this code.

What are the symptoms of the P2119 code?

  • The Check Engine Light will be on.
  • Vehicle may idle only.
  • Vehicle will have reduced power output and slow throttle response (Limp Mode)

How does a mechanic diagnose the P2119 code?

The first step is to check for codes with a scanner and confirm the problem still exists. This is accomplished by clearing the code then test driving the vehicle. Primarily a mechanic will use a scan tool to monitor the data from two sensors: the TPS and the TPPS. Most of the time the problem will be apparent in the scan tool data.

If the data is good but the code and or symptoms still persist, it will be necessary to test each component individually. A visual inspection of the throttle plate operation should be first followed by pin-point tests at each component in the ECTS system. Pin-point tests will be outlined differently for each manufacturer and should be researched with a professional shop information system.

Common mistakes when diagnosing the P2119 code

A common mistake made is the failure to check if the throttle valve is actually moving. Internal components in the throttle body can break. If this occurs, it is possible the TPS will indicate the throttle valve is moving, but the valve won’t actually be moving.

Electrical connector issues are common on all vehicles and all systems. Problem areas are not always visually apparent and warrant a more comprehensive look at the wiring harness and connectors of each component. It is easy to miss problems with connectors as these problems are not readily apparent to the eye.

How serious is the P2119 code?

This code indicates a problem with the the throttle control system which is a vital system to the speed of any vehicle. If this system were without any failsafes, a failure in the system would pose significant danger to the occupants and any bystanders. For this reason, if this code is set, the vehicle will usually lack a significant amount of power. Some manufacturers choose to put the vehicle into a shutdown mode for safety reasons. The programming and failsafe modes will vary from manufacturer to manufacturer.

What repairs can fix the P2119 code?

The two most common repairs are the throttle body assembly and the throttle pedal assembly. Both components contain position sensors used by the PCM to detect the position of the throttle pedal under your foot and the throttle valve at the beginning of the intake manifold.

Additional comments for consideration regarding the P2119 code

Personally I do not appreciate the use of electronically controlled throttle systems (ECTS) found on most modern vehicles. It over complicates a very simple and sound cable system that has been in use for many decades. In addition, the introduction of the ECTS system increases the cost of ownership for any vehicle. In my opinion, it creates more components to fail that are expensive and often complicated to replace.

It is the manufacturer's goal to gain a more precise control over the motor's operation. They may have accomplished this, but the gain in control is minimal in comparison to the significant cost of ownership passed on to the customer. Not to mention the added inconvenience of a car that won’t go when these systems fail. The traditional cable system would not and could not contribute to the need for roadside assistance.

This opinion is readily discussed among mechanics and customers that experience failures of the ECTS. It is often the case that vehicle manufacturers will lack the real world perspective of the customers they are selling their cars to.
