The Engine Control Module (ECM) recognizes that the engine is idling above the designated idle RPM range, which sets off the P0507 code. Depending on the vehicle model, the regular engine idle typically ranges from 600 to 800 RPM.

Can I drive when having P0507?

You can still operate your car if you have a P0507 fault code. It won’t be too difficult to transport it to the closest workshop. However, you can encounter problems starting the automobile, rough transmission engagement, and constant high noise when the engine is idling.

How can excessive idle be fixed after cleaning the throttle body?

Until the computer retrains itself on idle, the idle will initially be high. More air was able to enter the engine when the throttle body was cleaned, and the computer is adjusting by supplying more fuel. If you put the car in drive and let the idle come down for two to three minutes with all the accessories off, the idle will relearn. After that, run your air conditioner for three minutes with the blower on high. This should put it right. If it doesn’t work, I suggest having a mechanic, like one from YourMechanic, check out your car.

What could be the source of my engine’s excessive idle?

High Idle Speed Potential Causes The cooling system might need work, and the engine could be overheated. The fuel pressure regulator could need to be replaced since it may be functioning at too low of a pressure. Perhaps the timing of the ignition has to be adjusted.

Vacuum leaks may result in excessive idle.

A vacuum leak can increase the engine’s RPM at idle in a fuel-injected motor. In fact, if the leak is significant enough, the idle speed can be doubled. The engine’s O2 sensors will notice that more oxygen is entering the intake manifold when a vacuum leak is discovered.

How much does repairing an idle control valve cost?

An idle control valve can be replaced for anywhere between $120 and $500. Depending on the type and model of your vehicle, the cost of the parts alone will range from $70 to $400 or more. Because it doesn’t take very long to remove and replace the old idle control valve, the labor expense should just be $50 to $100.

If you are skilled in auto repair, you may perform this replacement task on your own and save $100. However, it is worth spending the extra money to have a professional replace the valve for you if you lack the courage to do it yourself.

In the long run, the replacement cost is generally not so high. Your engine could be harmed if the control valve were left in situ and not replaced. The cost of repairs would then run into the thousands.

How do I change my electronic throttle body’s idle speed?

As automobiles age, the idle performance often changes, but fortunately, the adjustment is not too difficult. Finding and rotating the screw on the throttle body will change the idle RPM.

The following steps will show you how to change the idle RPM:

  • Open the hood, turn on your car, and let it warm up completely. While the automobile is moving, you will make this change. Be careful not to touch any hot engine components.
  • Locate the electronic connector holding the idle air adjustment valve to the throttle body and detach it.
  • From the air filter to the throttle body, follow the air intake hose. Look for a screw on the throttle body (possibly covered by a plastic cap). If the plastic top is still attached, pry it off.
  • Reconnect the electrical connection to the idle air adjustment valves once the idle has been changed to aim for 650 RPM. Turn off your car and lower the hood.
  • To modify the idling, turn the idle screw.
  • To raise RPM, spin the screw to the left; to decrease RPM, turn the screw to the right.

What causes an unexpectedly high RPM in the idle air control system?

Idle Control System RPM Higher than Expected is the meaning of the general powertrain code P0507. The engine computer has identified that the engine idle speed has exceeded the limit, according to this OBD-II code, which is one of a group of fault codes (P0505 to P0509) that relate to a problem with the idle control system.

Does the computer need to be reset after the throttle position sensor is replaced?

I’m here. If your engine’s throttle body has to be replaced and there was a pending code, the code will be cleared. The ECM (computer) would require a hard reset if the code was a permanent hard code. After around 13 minutes, unplug the negative battery cable (-), then reconnect it and make sure it is tight. As it enters a learn cycle, the engine light will turn off and all codes will be cleared. Unless it is causing several sensors to activate codes, the check engine light will stay off if the issue has been resolved, but if it has not, it will turn back on after 10 starts or three days of driving. Seek out a specialist, like one from Your Mechanic, if you require more help in resetting the ECM.

How can I calibrate the position sensor for my accelerator?

The ignition switch must be turned to the ON position before depressing the accelerator pedal fully and slowly from idle to full throttle in order to calibrate the accelerator pedal assembly. Three times through the process.

How can a throttle body be cleaned without taking it apart?

The throttle body can indeed be cleaned without having to remove it. Simply spray a throttle body cleaner on it and wipe it down with a clean cloth or toothbrush to clean the throttle body without having to remove it from the engine.

Cleaning the valve’s interior can be challenging because it won’t fully open unless the engine is running and the gas pedal is depressed. Although you will be able to push it open, you must proceed with caution as you might run into opposition.

Ask someone else to turn the car on and press the gas pedal in order to make this phase of the cleaning procedure simpler. You’ll find it easier to manually open the valve if the gas pedal is compressed.
