What causes a P0507 code?

What causes a P0507 code?

What Does P0507 Mean? 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.

What are the signs of a bad idle control valve?

5 Symptoms of a Bad Idle Air Control Valve (and Replacement Cost)

• Intermittent Idle Speed.
• Check Engine Warning Light.
• Rough Idling.
• Engine Stalling.
• Load Causes Stalling.

What happens when idle control valve goes bad?

If the idle control valve fails completely, it may leave the vehicle without a source of air to maintain a proper idle. This may result in the engine stalling while operating, and in some cases may result in an engine that will not idle at all, and stalls as soon as it is started.

How much does it cost to fix a idle 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.

How do you test a idle control valve?

Here is how to test and clean the valve:

1. 1) Open the hood of your vehicle.
2. 2) Pull the electrical plug off the control valve.
3. 3) Take out the idle control valve and flip it over.
4. 4) Take your voltmeter and set it to “Ohms.”

What causes RPMs to fluctuate at idle?

Why does my engine’s RPM seem to fluctuate (runs rough)? Many engine performance problems can be linked to maintenance issues such as stale fuel, dirty air filter, fouled spark plug, and deteriorated oil. Engine hunting and surging at idle is usually caused by a fuel delivery, air leak, or governor system problem.

Is rough idle dangerous?

A rough idling car is more of an inconvenience at first but if the problem is not solved it can quickly lead to bigger problems such as slow acceleration, stalling and eventually a vehicle that will not start at all. Most of these conditions can make the vehicle dangerous to drive.

What causes hard idling?

Fuel system Low or high fuel pressure from a dirty fuel filter, defective fuel pump, clogged fuel tank strainer, bad fuel regulator or dirty/clogged fuel injectors can cause rough idling.

What should your rpm be while parked?

For the majority of passenger cars, idle RPM’s should be somewhere between 600 and 1,000 RPM’s.

Why is my car chugging in idle?

Along with faulty spark plugs, a build-up of dirt and grime is the likely cause of cars stuttering when idle. A clogged filter or fuel injection system can starve your engine of fuel or oxygen, causing your car to judder and shake.

Why does my RPM go up and down while parked?

If the engine can’t keep idling, it will continue trying to get it revved up to compensate. The cause of the erratic engine you’re experiencing could be a vacuum leak, sensor failure, or an EGR system malfunction.
