Error P0507 - Idle Speed ​​Control System - RPM Over Range

Trouble code P0507 - Idle speed is higher than expected.

The Check Engine Light is on on your dashboard and have you read the P0507 trouble code in the engine control module memory?

But what does this mean and how to fix this problem? Which part should I replace and in what order should I start looking for the problem?

In this article, you will learn about the symptoms, causes and solutions, and how to get rid of this trouble code as quickly as possible.

How does a mechanic diagnose a P0507 trouble code?

When diagnosing this error code, a mechanic will do the following:

• Reads all stored error codes using an OBD-II scanner.
• Review all saved data and clear error codes.
• Will test drive the car to make sure there is a problem.
• Check the vacuum wires for damage and also check for intake air leaks.
• Check the throttle body for large amounts of carbon buildup and the throttle body for proper opening and closing.
• Determines the engine idle speed when checking the idle air control valve and oil pressure switch in the power steering system using a diagnostic tool.
• Check the battery charging system.

Causes of P0507

• Air leaks, vacuum leaks (most common).
• Malfunction, jamming of EGR (exhaust gas recirculation).
• Faulty PCV valve (forced crankcase ventilation).
• Faulty/damaged/dirty throttle body.
• Faulty EVAP (gasoline vapor recovery system).
• Faulty IAC (IAC - idle air control).
• Power steering switch faulty.
• Accelerator pedal malfunction.

Symptoms of malfunction

The main driver symptom of P0507 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”.

They can also appear as:

1. The “Check engine” warning light on the control panel will light up (the code will be stored in memory as a malfunction).
2. Floating speed, as well as attempts to stall at idle.
3. Idle speed is higher or lower than normal.
4. The engine may stall if the idle speed is not maintained by pressing the accelerator pedal.

Depending on the symptoms, the severity of a P0507 code can range from moderate to severe. Therefore, it is recommended to resolve this issue as soon as possible.

Recommended Tools to Fix P0507

• Reading fault codes - FOXWELL NT301 scanner. For basic settings and adaptations, you may need a more advanced device.
• Finding air/vacuum leaks - smoke generator (you can do it yourself).
• Battery charger - can be purchased here.

Diagnosis and problem solving

Connect the scanner, read and write down all available codes. This information may be useful if an intermittent fault is later diagnosed.

If other codes are present along with P0507, diagnose and resolve them in the order in which they were stored. The most likely additional codes are usually related to the vacuum system.

Therefore, check the vacuum system for leaks caused by damaged vacuum lines. If necessary, repair and clear all codes before operating the vehicle. Then, retest the system to see if any codes are returned.

Checking using a connected computer or tester

Driver Information Panel

Checking system malfunctions using connected devices gives more accurate results, but at the same time requires deciphering special codes. For example, the monitor displays code p0441 or p0130 or error p0422. Oh, these car manufacturers, in human language they could write “replace the oxygen sensor” instead of P0130 or “check the canister valve” instead of P0441. But nothing can be done, the Lada Priora is also intended for export, so it is easier to write p0441 in the program than to give explanations in Russian, Kazakh, Arabic, Armenian and 10 other languages. And then attach special tables that indicate the meaning of certain codes. Just look at them and everything will become clear. But these tables are not included with the operating instructions. Either way, you can check them out below.

All fault codes for Lada Priora car systems consist of 5 characters. Here is a breakdown of Prior's errors.

Symptoms of P0507

The most common symptom of a P0507 code is that you will notice that the idle speed is higher than normal. You will also likely see a check engine light.

There may be other symptoms such as misfire, rough idling and acceleration if the cause of P0507 is a lean/rich mixture.

• High idle speed.
• Rough idle.
• RPM jumps XX.
• Check Engine.
• Uneven acceleration.

Reasons for error p0134

Unlike other errors in the ECU, code p0134 clearly indicates the original source of the problem - this is the first oxygen sensor of the catalyst. Therefore, the appearance of this error can only mean one thing: some problems have arisen in the lambda probe.

However, there may be several specific reasons for the error:

Using professional equipment to diagnose errors helps you quickly and accurately find out the cause of the problem. For example, if the auto scanner produces two errors at once - p0134 and p0171, then this indicates the presence of a short circuit in the network or a wiring break. Accordingly, it is possible to exclude a breakdown of the sensor itself as the cause of the malfunction.

According to existing statistics, in 95% of cases error p0134 appears due to a breakdown of the oxygen sensor itself. And only the remaining 5% of cases occur due to short circuit or insulation damage.

Self-diagnosis using BC

The owner can identify the main error codes of Priora 8 and 16 valves using the built-in controller and on-board computer (BC), without resorting to the services of car service diagnosticians. To do this, you must activate the vehicle testing option. The arrows on the instrument panel move to the maximum possible position. Further manipulations are performed in the following sequence:

Description and meaning of error P0507

This diagnostic trouble code (DTC) is a generic powertrain code, which means it applies to OBD-II equipped vehicles. While general, specific repair steps may vary depending on the make/model. Acedotally this code seems to be more common on Chevrolet, VW, Nissan, Audi, Hyundai, Honda, Mazda and Jeep vehicles. This P0507 code is one that sometimes triggers on vehicles that have electronic throttle control. That is, they don't have a conventional throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, a p0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (programmed) RPM. In the case of GM (and other) vehicles, if the idle speed is greater than 200 rpm higher than expected, this code will be set.

Errors Lada Kalina 1st generation - decoding

Important! The list can also be used for the VAZ Priora model - the digital codes are similar for both cars.

Exhaust gas outlet (0000)

The anti-lock braking system was developed when it became clear that when the wheels suddenly jam, the car loses stability and is difficult to control. Moreover, the quality of braking did not improve, and the car was pretty much carried off the road. Therefore, a system was developed that, by regulating the pressure in the brake system pipes, allows the wheels to turn slightly. This significantly improves vehicle dynamics, allowing the driver to control the vehicle more confidently. But despite its apparent simplicity, this is a rather complex process that requires the coordinated operation of many mechanisms included in the anti-lock braking system. If any of the components fails, a warning lamp lights up on the instrument panel.

You can often hear the question from drivers: “Why is the ABS sensor on?”

It is important to know that when the warning light comes on, it does not necessarily indicate a faulty wheel sensor.

VAZ errors and their solutions

Owners of domestic cars can easily find a problem with their car. This became possible thanks to the use of on-board computers and the introduction of modern equipment diagnostic tools. This article will describe in detail the errors and how to eliminate them in VAZ 2110, 2112, 2114, Kalina, Priora and how to eliminate them.

How to diagnose a car yourself

Do not rush to go to the service center. Although specialists use test benches to detect malfunctions, and their diagnostics are more accurate, every car owner is still able to find out the cause of the problem using information about the error codes of the on-board computer.

To view error codes recorded by the controller:

1. Sit behind the wheel, then press and hold the odometer button. It is located at the bottom of the dashboard.
2. Turn the key in the lock to position “1”. While turning the key, release the button. This will be followed by a quick set of readings on the instruments.
3. After this, press the button again: the display will show the controller firmware version.
4. Finally, press the button the last, third time to display the VAZ controller errors.

How to remove information about corrected errors from the controller memory

Sometimes, after troubleshooting, error messages remain in memory and periodically appear on the panel.

To clear an error code from memory:

• Write down and check for irrelevant codes that appear.
• Reset the daily mileage readings by pressing the corresponding button, after which the error code is guaranteed to be deleted from memory.

How to get rid of the "Check Engine" message

Sometimes drivers see a glowing orange icon at the bottom of the instrument panel. This is how the computer reports an engine malfunction. Self-diagnosis will not allow you to determine and correct the cause of the motor problem. However, the error often appears on serviceable cars. Therefore, to reset the problem code:

• Turn on the ignition, but do not start the car.
• Open the hood and use a wrench to loosen and remove the negative terminal on the battery.
• After a minute, return the terminal to its original position.
• Close the hood and turn the ignition key to position “0”.
• Turn the ignition back on and start the engine. After a short time the error should disappear.

If the above instructions did not help, it is worth carrying out a more accurate diagnosis of the car at a service center in order to correct the problem at an early stage.

Failures in the idle speed system (IAC) and ESC

Note: in cases where the computer displays error codes that indicate a break in the electrical wiring of a device, before troubleshooting the problem and purchasing spare parts, you must first see if the electrical wiring plug has come out of the connector of the corresponding device. Such incidents happened. Testers and computers are, of course, good, but nothing can replace the eyes of a car enthusiast. Good luck with the repair.

Electronics

This is a failure of electronics-related components:

• breaks in the electrical wiring harness; • failure of rotation speed sensors; • break or short circuit of the control valve activation coil; • failure of the return pump electric motor; • valve activation relay failure; • program failure, or failure of the ABS control unit.
