    How do you reset a throttle position sensor?

    The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module. via

    What are the symptoms of a dirty throttle body?

    When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed. via

    What is idle relearn?

    In the event you are experiencing an erratic idle after loading a tune or after performing any action that clears KAM (Keep Alive Memory), an Idle Relearn can help you get back on track. The KAM or “Keep Alive Memory” is the memory that is stored in the powertrain control module (PCM). via

    What causes engine idle problems?

    Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues. Let's go over each of these causes in more detail and learn how they can be remedied. via

    How do I reset my electronic throttle control?

    Resetting your electronic throttle control manually can be a tricky job. First, make sure the accelerator pedal is fully released. Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation. via

    What causes RPM to fluctuate while idling?

    Worn out or fouled spark plugs can cause rpm fluctuations. Check the engine vacuum and make sure there are no leaks. Leaks in the engine vacuum can cause rpm fluctuations. Replace the fuel filter if it is clogged or dirty. via

    Can vacuum leak cause high idle?

    On a fuel injected motor, a vacuum leak can cause the engine's RPM at idle to increase. In fact, it's possible to double the idle speed if the leak is significant enough. When a vacuum leak is detected, the O2 sensors on the engine will detect extra oxygen is entering the intake manifold. via

    How do you fix high idle after cleaning throttle body?

    Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel. The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes. via

    What does a faulty throttle position sensor cause?

    The car might accelerate itself, hesitate to accelerate, or lack power when you are trying to accelerate. You may also experience difficulty in changing gears. There may be a dramatic drop in your cars' fuel economy as a result of a faulty throttle position sensor. via

    Does seafoam clean throttle body?

    Especially important for modern GDI engines, it cleans critical upper engine areas where fuel cleaners can't reach. Apply Sea Foam Spray through fuel injection throttle bodies to clean harmful engine deposits from intake valves and combustion chamber areas. via

    Can throttle body cause rough idle?

    If your car runs rough when idling, the cause just might be a dirty throttle body. The throttle body controls the amount of air the engine takes in, and when it gets dirty, the engine can't idle smoothly. via

    How do you clean a Nissan throttle body?

    How does electronic throttle control achieve the correct idle airflow?

    Normally, at engine idle condition, the electronic engine control is intended to operate the engine at a fixed RPM regardless of load. It does this by regulating mass airflow with the throttle command from the driver at zero. via

    What causes idle to go up and down?

    If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge. via

    Why is my RPM jumping?

    RPM fluctuation is a common symptom of worn-out spark plugs, especially in older vehicles. Spark plugs that are worn out are unable to correctly fire the fuel within the piston at the appropriate time. This might result in sluggish acceleration. When accelerating, your automobile may experience misfires and jerking. via
