    2004 SRX Code P2119

    Hello and good evening guys!!

    I have a 2004 SRX V6-
    I have been having trouble for almost a week now with some accelerating issues.

    Today I took it to the local car part store and had the codes ran. They came up with P2119.

    Now before I go to 5 different mechanics tomorrow...what is the most likely outcome?

    Sorry about my post, if it is vague.

    This may be the throttle body position sensor (TBPS), but before you do anything I would check to see if the throttle body isn't simply gummed up with carbon. If you remove the hose that runs from the air filter box to the top of then engine, you will see a silver open mouth with a air valve in it. The valve gets stuck if there is carbon build-up inside the mouth. BE CAREFUL what type of cleaner you use, since the TBPS is in the area and can be damaged with certain types of cleaner. Your local parts store should have a TBPS-safe carbon remover. The entire mouth should be completely clean for proper operation and the valve should be able to move freely. If not, you can try a bit of lubricant on the pivot points.

    If you are doing the job of cleaning the throttle body inlet as suggested, it's a good idea to disconnect the battery. If it's dirty with gum build up the engine's computer has "adjusted" as much as it can to these conditions. If cleaned now all of a sudden it's trying to deliver fuel based on the old condition and the engine will run poorly.

    Our vehicles are "run by wire" meaning when you step on the accelerator in the "old days" there was a direct cable link to control intake airflow. Now it's done electronically. The accelerator position is signaled to the computer and the computer sends a signal to throttle body and a small motor opens or closes the throttle body valve to adjust airflow. Anything along that path can cause an error if the computer doesn't get the proper feedback.

    Over time throttle bodies do get dirty and is worth checking as suggested by 08SRX. It's something you can do yourself. The cleaner is even available at Walmart. Repeating... do disconnect the battery before starting the project. Beyond that going to a trusted dealer isn't out of the question. They should have any service bulletins related to the error and have the tools to troubleshoot. I know parts and labor can be higher but if you pay a shop to "experiment" with swapping parts with your money you may be ahead at the dealer.
