What Does P0507 Code Means on Chevy and How to Fix it?
P0507 stands for “Idle Control System RPM Higher Than Expected,” according to the DTC. The particular cause of this code being set in your circumstance must be identified by a mechanic because it might happen for a number of different causes.
In this article, a detailed explanation of the P0507 error code’s significance and a step-by-step fix are offered. Along with a few possible reasons, symptoms, and preventative measures for this code.
What Does P0507 Code Means on Chevy?
When the engine is running at a greater RPM than what is allowed for idle, the Engine Control Module (ECM) sets off the P0507 code. Depending on the model of the car, the typical engine idle normally ranges from 600 to 800 RPM.
It is essential to comprehend the function of the Idle Air Control System in order to comprehend the significance of Code P0507.
The Idle Air Control System makes sure the car’s engine is running at the best idle speed when it is stationary. The use of the stereo, air conditioning, windshield wipers, and seat heaters, among other equipment and systems, will determine the vehicle’s optimal speed, among other variables.
The PCM (Powertrain Control Module) sets off the code P0507 when it notices that the idle engine speed is higher than the predetermined speed by design.
The “Check Engine” light will typically illuminate on the dashboard if the idle engine speed is 200 or more RPM over what is normal for most PCMs.
The Idle Air Control Valve, often referred to as a motor or actuator, is the primary part of the idle air control system. It works in tandem with the PCM to determine how much air is necessary for the system to operate at its best.
When we get to the answer later in this post, we’ll tell you more about this code and its causes. Here is how code P0507 is broken down:
- P: engine, gearbox, and emissions system-related issues are indicated by the powertrain code
- 0: SAE – Generic
- 5: auxiliary emission controls
- 0: high voltage air conditioning (A/C) clutch feedback circuit
- 7: cruise control system – too high an acceleration
How Serious Is Code P0507 of Chevy?
The majority of the time, P0507 won’t prevent you from driving. Despite the potential for a rougher ride, the engine keeps running.
P0507 will cause the engine to run at a higher idle RPM. When the transmission engages, it could also feel rough. On occasion, the engine’s idle speed may also increase suddenly.
What Causes Code P0507 on Chevy?
A vacuum leak in the engine is more frequently to blame for triggering a P0507 code than an issue with the idle speed control system.
The Idle Air Control (IAC) valve is often closed when the code is set, which only indicates that there is a vacuum leak and that the system is attempting to slow down the idle speed by shutting the idle air bypass circuit.
Before looking into other potential causes, it’s a good idea to rule out this issue first:
- Engines with vacuum leaks
- Broken or clogged valve for the idle speed and air controls
- Throttle body and/or electronic throttle actuator (ETC) motor issues
- Mechanical issues with engines
- Rounded exhaust
- Faulty or clogged IAC valve
- Faulty wiring and loose connections are examples of circuit problems.
- Sensor difficulties, problems with the air intake system
- Faulty power steering pressure switch
- Problems with the PCV system (positive crankcase ventilation)
- Network issues or control module issues (rare)
Other Symptoms of Getting on P0507 Chevy
Even if you lack experience, you can quickly and readily recognize a P0507 code. Keep an ear and look out for the following signs:
- When the “Check Engine” light is illuminated
- When the engine is in idle mode, it may sound noisier than usual.
- The engine may appear harsher than usual when it is idle.
- If the vehicle frequently stalls when in idle mode
- If the vehicle has a hard time accelerating
- Harsh engagement into drive or reverse due to high RPM at idle
How to Diagnose the P0507 of Chevy?
This error code won’t stop your car from moving, but it might cause the engine to stall, the idle to surge, the transmission to engage harshly, the car to be difficult to start, and/or other problems.
The mechanic generally follows these steps to diagnose the P0507 error code.
- Connects a scan tool to the DLC port on the car, then checks for any codes.
- Makes a note of the DTC freeze frame information for use during the test drive and clears the codes.
- Tries to reproduce the fault by driving the car in a test drive.
- Visually inspect the system and look for any leaks in the outside air or any torn vacuum lines.
- Tests the throttle body for excessive carbon buildup and correctly opens and closes it.
- Tests the IAC and power steering pressure switch while monitoring the RPM using a scan tool.
- Checks the charging system
How To Fix the P0507 Code on Chevy?
To diagnose the P0507 DTC, the majority of specialists will adhere to the following procedures. To finish these procedures, you might require some specialized technology and expertise.
- Start your car’s diagnostic procedure by connecting a reliable OBD-II scanner to it. For accurately identifying the car part that is malfunctioning, this is essential.
- By reading the system’s codes using the OBD-II scanner, you may verify that Code P0507 is present.
- Clear the system’s error codes, get the vehicle ready for a test drive, then repeat the error code’s occurrence to verify the diagnosis.
- Look over any broken vacuum lines, inspect them, and look for any possible leaks outdoors.
- The throttle body will now be thoroughly examined. The technician checks the throttle body air passages for carbon buildup, proper opening and closing, and other issues.
- The power steering pressure switch and the IAC’s RPM speed are both tested using an OBD-II scanner.
- The charging system test is the last phase.
- The technician restarts the system and clears the system’s codes after all repairs and replacements have been made before doing one more test drive.
Possible Things you May Need to Repair for Code P0507
This issue code can be fixed with a few straightforward fixes, but you must always run diagnostic tests first. If you begin replacing parts haphazardly, you risk spending money on unnecessary replacements.
Some of the most popular P0507 patches are listed below:
- Make the throttle body clean.
- Vacuum up the idle air control valve.
- Rectify any intake or vacuum leaks.
- Swap out a bad sensor
- Exchange the throttle body electronic
- Replace a broken idle air control valve.
- Set the throttle cable to the proper position.

Can you Drive if you have a P0507 code?
When a problem arises, P0507 shouldn’t stop the vehicle from going to a safe location. The idle oscillations may make it difficult to start the car, but they normally don’t cause the engine to go out.
Still, avoid delaying maintenance because of a P0507 error code. An excessive idle RPM can harm other engine parts in your car.
Common Errors to Avoid when Repairing a P0507 Code
Replace no component unless you are certain that it is the cause of the P0507 error. The replacement of the throttle body, idle air control valve, or power steering pressure switch before visual inspection or vacuum leak inspections is a frequent error.
