Honda Accord P0507: Idle Air Control – RPM Higher than Expected
Tech Notes What does this mean? The auto repair labor rates vary widely across the country, and even within the same city. When is the code detected?
The idle speed is more than the target idle speed by rpm or more. The operating of the throttle valve is varied to allow for optimum control of the engine idling speed. The ECM calculates the actual engine speed from signals of crankshaft position sensor POS and camshaft position sensor.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.Honda Idle Surge Common Problems and How to Fix Diagnose Displate Giveaway
The optimum value stored in the ECM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load air conditioner, power steering and cooling fan operation, etc. Get Access to Factory Service Manuals.

In addition, you may also find a P The idle plate is now in a different position and changes idle speed.
However, a P can also be caused by a vacuum leak, so check the PCV valve and hose, EVAP canister purge valve, intake manifold gaskets and brake booster hose for leaks. Start the engine.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. This code is related to P and P The P code means the idle control system has excessively high RPM. Once this code is triggered it puts the vehicle into a failsafe mode and the Check Engine Light is illuminated on the dashboard. Mistakes are made when simple items are overlooked due to not following steps in the proper order or not performing them at all. A few different systems are involved in the P code and if one system is overlooked parts that are working properly may be replaced.
P should not prevent the vehicle from driving to a safe location once the malfunction occurs. The idle fluctuations may cause the vehicle to have trouble running but in most cases the engine will not die. The idle air valve and the throttle body can build up excessive deposits of carbon over time usually over k miles.
This buildup can cause issues with the operation of these parts by clogging them or stopping proper movement. A throttle body cleaner can be used to removed the carbon buildup. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

When is the code detected? The idle speed is more than the target idle speed by rpm or more. P Description The Engine Control Module ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is varied to allow for optimum control of the engine idling speed.
The ECM calculates the actual engine speed from signals of crankshaft position sensor POS and camshaft position sensor.

Posted and Edit by AutoCodes.In simpler terms, the idle speed is persistently faster and above the pre-determined RPM level for a specified amount of time. Error Code P means the idle speed is faster than normal.
This code is sometimes triggered on vehicles with electronic throttle control. They mostly depend on electronics and sensors to control the throttle.
In many cases, the idle speed that goes more than RPM higher than the desired or expected speed will trigger the error code. Because this error code refers to idle air control malfunction, the first thing you need to inspect to diagnose is to check the freeze frame data to get a good picture of when the malfunction took place.
It is also good to test the basic functionality of the system; turn the steering wheel as if you are parking the vehicle while it is stopped and the engine is idling. Make sure you pay attention to the data stream and check the higher RPM, also check whether the system is responding. When the error code P also shows up, this means there is a carbon buildup in either the Throttle Body air passages or the Idle Control Motor.
This error code is more of an informational code than a warning code. Thus, if your scan tool shows other codes, it is better to diagnose them first. If there are no other codes, the first thing you need to do to fix error code P is to check the intake air system for air or vacuum damages and leaks.
If there are no other symptoms than the DTC itself, simply clear the codes and see if it comes back after a few drives. Check the PCV valve as well and see if it is blocked and needs a new replacement. Try swapping in a new throttle body if available and see if it can fix the problem.

You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. So you should chech it on our car models.
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
Parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Code Search Please fill the "Code Box" to find engine fault code.

Now don't ask yourself; What should you do with P code? The solution is here :.It is typically triggered when the engine idle speed is rpm or more over the predetermined limit set by the manufacturer.
It is a generic code, which means that it has the same for the Honda Accord as any other vehicle. Here are the typical symptoms for the Accord:. There are a lot of potential causes to P The Idle Air Control Valve is often not the cause of the code.
Here are some of the most common causes of P in the Honda Accord, as well as waist to troubleshoot them. Keep in mind that there are differences in model years. It would be a good idea to start by looking for a vacuum leak and move forward from there. A leaking vacuum system will often cause the Accord to idle higher. When the vacuum system leaks, it allows extra air to enter into the combustion chamber.
This air allows for a slightly higher combustion, increases the RPM and throws the code. A vacuum leak can come from bad vacuum hosethe intake manifoldEGR Systemor about anywhere else that air flows through. Most modern fuel injected engines are equipped with an idle air control valve. Not all of them are though. A throttle body opens and closes millions of times in the life of a vehicle. All of the air that passes through it can slowly cause it to collect grime.
This grime can change the idle characteristics of the vehicle. Alternatively, if the throttle body has been damaged, it may not be properly regulating air flow, and the code may be thrown. P is a serious issue. Good luck! Faster Idle Speed — Assuming that the code has been thrown due to a legitimate issue, you should notice the engine running faster when not pushing the gas.
It is common to feel the whole vehicle jerk when put into gear with P Vehicle Takes off Faster — With the engine idling higher, people report feeling the vehicle take off when releasing the brake pedal. This can make driving more dangerous.
Vacuum Leak A leaking vacuum system will often cause the Accord to idle higher. Idle Air Control Valve Most modern fuel injected engines are equipped with an idle air control valve. A Typical Throttle Body Alternatively, if the throttle body has been damaged, it may not be properly regulating air flow, and the code may be thrown.
