What Does Code P0507 Mean?
- P0507 definition: Idle Control System RPM Higher Than Expected
- Issue Severity: LOW – Continued driving for a short period of time is okay
- Repair Urgency: Get this fixed within the next month to prevent drivability problems and excessive fuel consumption.
- Diagnosis: This trouble code will not prevent your vehicle from driving, but you may experience engine stalling, high idle rpm, harsh engagement of transmission, difficulty starting, and/or surging idle.
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 600-800 RPM depending on the model of the vehicle.
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
- Check Engine Light
- Hard to start engine
- Rough engine idle
- High engine idle
- Harsh engagement into drive or reverse due to high RPM at idle
- Engine stalling
How Do I Fix Code P0507?
With an idle fault, the first step is to get it diagnosed to figure out what is causing the problem.
If your vehicle has this fault and you’re not comfortable diagnosing this issue at home, we recommend finding a RepairPal certified shop nearby to pinpoint the problem and give an accurate estimate for repairs.
These shops can not only help you figure out what’s going wrong before you waste time and money on the wrong parts, but they also offer a minimum 12-month, 12,000-mile warranty and stand behind all their estimates with guaranteed fair pricing.
How Much Does It Cost to Fix Code P0507?
P0507 can be caused by anything from an intake or vacuum leak to a dirty throttle body to a faulty electric throttle control actuator. It’s impossible to give an accurate estimate without properly diagnosing the issue first.
If you take your car to a shop for diagnosis, most shops will start with an hour of “diag time” (the time spent in labor diagnosing your specific issue). Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0507 code.

DIY Steps to Diagnose Code P0507
Engine code P0507 could be caused by a number of things, including dirty components, a vacuum leak, or failed parts. If you’d like to try to fix code P0507 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis. Keep in mind this is an intermediate-level diagnosis and repair and not recommended for beginners. Diagnosis requires more specialized equipment beyond what the FIXD Sensor can provide and it can be a time and labor-intensive process for inexperienced DIYers.

This repair requires mechanical knowledge and is not recommended for beginners.
Tools/parts needed (our top picks from Amazon):
- Throttle body cleaner
- Idle air control valve cleaner
- Spray bottle of water
- Basic hand tools
STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.
Use FIXD to scan your vehicle to verify P0507 is the only code present. If other codes are present, they must be addressed first.
STEP 2: INSPECT THE INTAKE AND VACUUM LINES.
Conduct a visual and audible inspection of the vacuum lines, and any intake connections to make sure there are no signs of disconnection or outside air leaks. This includes the intake pipe between the throttle body and MAF. Listen for a hissing sound, which can be a sign of a vacuum leak. Spray water over the intake area and listen for an idle RPM stumble. If it goes down, there is an intake leak. Concentrate the stream on different hoses and gaskets until you find your leak.
STEP 3: CLEAN THE IDLE AIR VALVE AND THROTTLE BODY.
Remove carbon buildup from idle air valve and throttle body using their corresponding cleaners, ensuring opening and closing capability. DO NOT spray the throttle body with the cleaner. Spray it on a rag and wipe the butterfly surfaces and housing clean.
STEP 4: ADJUST THE THROTTLE CABLE.
If the vehicle has a cable-operated throttle body, make sure the cable isn’t adjusted too tight, causing the throttle to be slightly opened at idle. If it is out of adjustment, adjust to spec and retest.
If these steps haven’t worked, you may need to replace the power steering pressure switch, idle air control valve, or electronic throttle body. It’s also possible that the vehicle may need to have the idle air volume relearned. Most automotive repair facilities can perform these services.
Common P0507 diagnosis mistakes
Prematurely replacing the power steering pressure switch, throttle body, or idle air control valve before attempting to visually inspect and clean the carbon buildup in the idle air valve and/or throttle body, or check for vacuum leaks.
