What can cause P0507?

There are many potential causes of code P0507.

• Intake/vacuum air leak (most likely cause)
• Faulty Idle Air Controller (IAC) Valve.
• Faulty power steering pressure switch.
• Faulty electric throttle control actuator.
• Improperly adjusted throttle cable.
• Carbon buildup on the throttle body.

What causes intermittent rough idle?

Causes of a rough idle. 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.

How do you reset the idle air control valve on a Chevy truck?

You can reset the idle air control (IAC) valve by turning the car on, putting the car into park, pressing the brake down, then pushing the gas pedal down, counting down about 5 seconds, turning the car off, waiting 10 seconds and start the car again, checking to see if the car is idling properly.

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.

Where is the idle air control valve located?

throttle body
Locating the Idle Air Control Valve The IACV is usually located on the intake manifold near the back of the throttle body.

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.

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.

Can a dirty MAF sensor cause rough idle?

The MAF measures the rate of air flowing into fuel-injected engines. A dirty or faulty MAF will cause an engine to idle roughly, as well as stall when idling.

What happens if I unplug the idle air control valve?

If it works properly, stopping it would cause panic to your inactive engine. Normally, if you turn on your car, the inactive air control valve will increase and decrease the rpms engine slowly. It would be a sign that your IAC works.

What are the symptoms of a faulty idle control valve?

Common signs include irregular or unusually high idle speed, the Check Engine Light coming on, and stalling while idling.

Can you clean a idle air control valve?

How do you clean an IAC valve? After relocating the IAC valve, you need to unscrew it and detach all the wires. You can clean it by soaking it in gasoline and blowing compressed air into it. Then, reattach it with the screws and reconnect the wires.

What are the symptoms of a failing idle air control valve?

Common signs include irregular or unusually high idle speed, the Check Engine Light coming on, and stalling while idling….Usually a bad or failing idle control valve will produce a few symptoms that can alert the driver of a potential issue.

• Irregular idle speed.
• Check Engine Light comes on.
• Engine stalling.

Can I clean my idle air control valve?

How do I reset my 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.

How do you reset a 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 causes an engine to idle 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.

Why is my RPM needle jumping in park?

Among the potential underlying causes are vacuum leaks, EGR system malfunctions, malfunctioning oxygen sensors, dirty fuel injectors, fuel pump malfunction, faulty spark plugs, a faulty mass airflow sensor, or a faulty throttle position sensor.

What happens if I unplug my mass airflow sensor?

Q: Car runs with the mass airflow sensor unplugged. If you plug it in it will die if the car is running. If you unplug the mass air flow sensor the car will start. If you try to plug it in while it’s running the car will die.
