How do I fix code P0507?
What would cause a P0507 code?
The P0507 code is triggered when the Engine Control Module (ECM) detects that the engine is idling higher than the specified idle rpm range. The standard engine idle is usually between 600-800rpm based on the model of the vehicle.
How do you fix the idle air control system RPM higher than expected?
Check the PCV valve as well and see if it is blocked and needs a new replacement. Inspect the IAC (Idle Air Controller) if it is equipped, and verify its performance. Try swapping in a new throttle body (if available) and see if it can fix the problem.

Issues such as acceleration difficulties and excessive idle engine speed can cause harm to the engine in the long run, though, so make sure to take care of the problem as soon as possible.
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.
How do you fix high rpm in a car?
If the RPMs are too high, try dropping it down a gear. This can solve the problem quickly and easily. Depending on what equipment the engine is hooked up to, you may be able to control the RPMs with gears. If the RPMs are too high, try dropping it down a gear.

Can you adjust an idle air control valve?
How do I adjust the idle on my throttle body?
SETTING ENGINE IDLE SPEED
Turn idle speed screw counter-clockwise until the throttle butterfly is fully closed. Then continue to turn idle speed screw counter-clockwise until you can see between the screw and stop (or if using a feeler gauge - . 010") then turn clockwise one full turn.
Can I drive with a P0505 code?
Trouble code P0505 should be diagnosed and repaired as soon as possible. Not recommended, however, you may drive your vehicle while trouble code P0505 is present unless the engine stall or stumbling is is severe enough to hinder proper vehicle operation. Erratic or lack of idle control may be noticed.
What is engine code P0505?
Diagnostic trouble code (DTC) P0505 stands for “Idle Control System.” The code may be accompanied by erratic idle speeds that can lead to stalling and other issues. On most older vehicles, the idle control system relies on an idle air control valve (IAC) on or near the throttle body.
Can you drive with a bad idle air control valve?
Technically, you may be able to drive with a bad IAC—but you should not continue doing so. A bad IAC can potentially lead to stalling, which can compromise vehicle safety. Plus, you won't pass a state emissions test if the check engine light is on due to a bad IAC.
How long does it take for a car computer to reset?
The readiness monitors will remain until the car has been driven long enough for the computer to evaluate the various system and sensors. The amount of time can vary based on the vehicle. In some cases it can take up to 100 miles for all of the computer monitors to completely reset.
How long does it take a car to relearn idle?
Q: How long does it take for a car to relearn idle? Anywhere from 5 to 25 minutes. It depends if we include warming up the engine during this time. Nonetheless, the car doesn't require too much time to relearn the correct airflow intake, given that you're doing everything correctly.
How do you reset the idle of a car after replacing the battery?
What code is P0174?
Diagnostic trouble code (DTC) P0174 stands for “System Too Lean (Bank 2).” The code indicates that your car's computer has detected a lean running condition.
What does po171 code mean?
The P0171 code means that, on the first bank of the engine, the fuel system is running weak or a vacuum leak exists near this side of the engine. A lean condition occurs when the engine either receives too little fuel or too much air.
How do I fix code P0068?
How do you reset throttle body?
Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.
What happens if car idles too high?
High idle speeds waste fuel, cause extra wear and tear on your engine, and can be unsafe as well. If your foot should slip off the brake as the engine revs, it could cause your vehicle to lurch forward, putting other drivers and even pedestrians at risk.
Can bad fuel injectors cause high idle?
One of the most common symptoms of faulty fuel injectors is an extremely violent or rough engine idle.
Why is my RPM at 1 when I'm stopped?
This may be a sign of a failing idle air control valve. However, when the engine RPM drops below the normal range of 800 RPM (for most cars), it is more than likely that you are dealing with an IAC valve problem.
Why is my car at 1 RPM in park?
The idle problem may be a result of a dirty or faulty idle air control valve. This valve is controlled by the vehicle's computer and will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage.
Is 1000 RPM idle bad?
In most of today's cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won't feel smooth. Rough idle is easy to detect when you start your vehicle, and it may be dependent on the engine temperature when you start your car.
How do I reset my electronic throttle control system?
Fully depress the accelerator pedal for 10 seconds. At this point the check engine light should change to blinking slowly indicating “Erasing ECU Memory”. 8. Release the accelerator pedal and turn the ignition switch to off.
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.
Do you have to reset computer after replacing throttle position sensor?
After replacing the throttle body to your engine, if the engine light was on and has a pending code, the code will go away. If the code was a hard permanent code, then the ECM (computer) would need a hard reset. The engine light will go out and clear all codes as it goes into a learn cycle.
How do you adjust engine idle?
Turn the idle screw, now exposed from the protective rubber coating, in order to adjust the idle. Loosen the screw in a counter-clockwise fashion to increase idle speed or tighten it in a clockwise manner in order to decrease the idle speed.
How much does it cost to fix an idle air control valve?
The replacement cost of an idle control valve is anywhere from $120 to $500. The cost of the parts alone will be between $70 and $400+, depending on the make and model of your vehicle. The labor cost should only be around $50 to $100 because it doesn't take that long to remove and replace the old idle control valve.
What happens when idle air control fails?
When the idle air control valve fails, it inhibits the flow of air through the engine. When the car can't receive air, it leads to engine stalling. The severity of this symptom can range from occasional stalling at first, to stalling immediately after ignition.
