P2119 Fault Code

Long Description

Fault code P2119 is logged when the powertrain control module (PCM) has detected an issue with the throttle actuator control and throttle body range.

This happens when the throttle valve is not in the position that it is expected to be according to the PCM.

These components fall under the electronic throttle control system (ETCS). These are found in modern vehicles instead of the traditional mechanical linkages that were used in the original throttle systems.

Fault codes with this system can cause the vehicle to have acceleration problems and other performance issues.

Manufacturers like Chevrolet, Ford, Nissan, and Toyota are some of the most commonly searched alongside this issue. Of course, this is limited to modern vehicles that have an ECTS.

Other Signs of This Problem

There can be a number of noticeable issues when it comes to issues with the ETCS. These will typically be noticed when it comes to accelerating.

The most obvious symptom will be the presence of the Check Engine light on the dashboard.

Another fairly common symptom of this issue is the engine being unable to accelerate. This will leave it idle regardless of gear or how much the throttle pedal is depressed.

With certain manufacturers, this fault code will put the vehicle in limp mode. This includes reduced power and slow throttle response. This issue will remain until the cause of the fault code is fixed.

There may be additional fault codes that can help pinpoint the cause of the issue. Be sure to look out for codes like P0122 to P0124, P1125, and P2135. These can show if there is a sensor issue at hand.

What Could Be The Problem?

The causes of this fault code can typically be found in the ETCS itself. They can be either electrical or mechanical in nature.

One of the most likely causes is a faulty throttle position sensor (TPS). In addition to this, there may be electrical faults in the TPS sensor like an open or short circuit.

It is also possible that the throttle pedal position sensor (TPPS) is also faulty. Similarly, its circuit can hold various faults. This is also called the accelerator pedal position (APP) sensor sometimes.

A defective throttle body is another potential cause of this problem.

In some cases, a faulty PCM can cause this issue. However, this will typically be accompanied by a number of fault codes.

Fixes

Fixing this issue can be fairly straightforward with any luck. It will typically require replacing parts or fixing electrical issues in the relevant circuits.

Checking the position sensors is one of the first steps to take. If either the TPS or the TPPS sensors are faulty, it is important that they are replaced.

Both sensor circuits need to be checked for electrical issues. These can include loose connections or damaged wires. Either of these issues need to be fixed.

The throttle body needs to be inspected. If it is damaged or faulty, it needs to be replaced.

If it can be determined that the PCM is faulty, it needs to be fixed or replaced by the manufacturer.

Seriousness

Fault code P2119 is a moderately serious problem. It can cause a number of fairly significant issues in terms of driveability and performance. It also has the potential to put the vehicle into limp mode.

It is a good idea to have this fault code fixed immediately before there are further problems. This is also to restore driveability if it has caused limp mode.
