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.

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.

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:

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.

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.

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.

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.

VAZ error codes and their interpretation

Dear friends, since carburetor VAZs are already history, and the vast majority of VAZ owners, from classics to grants, are happy owners of injection engines, this does not eliminate the need to diagnose the engine and eliminate certain problems. And if earlier we simply changed spark plugs in any incomprehensible situation, adjusted the ignition and cleaned or purged the carburetor, then in an injection engine everything is somewhat more complicated, since everything is controlled by the ECU - the brains of the car. Many people acquire on-board computers, but not every bookmaker knows how to decipher errors ; most bookmakers simply show the error code , if there is one, and the car owner (or a diagnostician) will have to decipher this error And since every check error makes it expensive to go to a diagnostician, and the choice of bookmakers in the budget segment is quite large, and almost any driver will be able to purchase this useful device in a car, we are posting VAZ error codes with decoding so that you can easily identify one or another engine error.

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.

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.

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.

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.
