The two most common repairs are the throttle body assembly and the throttle pedal assembly. Repairing/replacing the Throttle Pedal Assembly Repairing/replacing the throttle Body (this consists of the TPS, throttle valve and throttle valve motor) The programming and failsafe modes will vary from manufacturer to manufacturer. Some manufacturers choose to put the vehicle into a shutdown mode for safety reasons. For this reason, if this code is set, the vehicle will usually lack a significant amount of power. ![]() If this system were without any failsafes, a failure in the system would pose significant danger to the occupants and any bystanders. This code indicates a problem with the the throttle control system which is a vital system to the speed of any vehicle. It is easy to miss problems with connectors as these problems are not readily apparent to the eye. Problem areas are not always visually apparent and warrant a more comprehensive look at the wiring harness and connectors of each component. If this occurs, it is possible the TPS will indicate the throttle valve is moving, but the valve won’t actually be moving.Įlectrical connector issues are common on all vehicles and all systems. Internal components in the throttle body can break. Common mistakes when diagnosing the P2119 codeĪ common mistake made is the failure to check if the throttle valve is actually moving. Pin-point tests will be outlined differently for each manufacturer and should be researched with a professional shop information system. A visual inspection of the throttle plate operation should be first followed by pin-point tests at each component in the ECTS system. If the data is good but the code and or symptoms still persist, it will be necessary to test each component individually. Most of the time the problem will be apparent in the scan tool data. Primarily a mechanic will use a scan tool to monitor the data from two sensors: the TPS and the TPPS. This is accomplished by clearing the code then test driving the vehicle. The first step is to check for codes with a scanner and confirm the problem still exists. How does a mechanic diagnose the P2119 code?
