Idle Control System RPM Higher Than Expected
The computer detected idle speed above its target under the monitor conditions. A brief fast idle during a cold start is not by itself the fault definition, so the setting conditions matter. Unmetered air, throttle behavior or idle control may be involved. This code is not an instruction to adjust a screw or replace the throttle, especially if the vehicle pulls unexpectedly.
Can I keep driving?
High idle that pulls the vehicle, unpredictable throttle response, stalling or abnormal braking calls for a safe stop and towing. With no symptoms and a steady light, ask a shop before further driving; do not adjust idle yourself.
What does this code mean for your car?
The same code can need different checks depending on the model and engine. Enter your vehicle details to find relevant sources and checks.
Symptoms
- High idle remaining after warm-up
- Increased vehicle creep when a gear is selected
- Steady check engine light
Possible causes
- 1Intake or PCV air leak
- 2Throttle not closing as required
- 3Faulty idle valve or actuator where fitted
- 4Adaptation issue or implausible control input
These possibilities are not ranked by frequency and do not diagnose your vehicle.
Checks you can safely do yourself
Safe checks only: engine off and cold, car on level ground.
- Save the code and freeze-frame data if your scanner offers them, without clearing anything.
- Record idle RPM already displayed and whether the engine was cold or warm; do not hold the accelerator or attempt a throttle relearn.
When you need a shop
Have target and actual idle compared, intake and PCV sealing checked, and throttle or idle-actuator behavior tested. Unexpected creep or abnormal pedal response calls for towing.
How much does it cost?
A US repair estimate needs a diagnosis and a local shop quote.
No verified US repair quote is available for this fault. The price depends on diagnosis, vehicle, parts and local labor; request 2-3 itemized quotes.

Can I keep driving with P0507?
High idle that pulls the vehicle, unpredictable throttle response, stalling or abnormal braking calls for a safe stop and towing. With no symptoms and a steady light, ask a shop before further driving; do not adjust idle yourself.
What can cause P0507?
Possible causes include intake or PCV air leak; throttle not closing as required; faulty idle valve or actuator where fitted; adaptation issue or implausible control input. These are diagnostic possibilities, not a confirmed diagnosis or a parts shopping list.
Does clearing the code fix the problem?
No. Clearing a code does not repair the problem or prove that no fault exists. It may erase useful evidence and reset readiness monitors. Save codes and freeze-frame data first; confirming a repair requires the vehicle-specific checks.
What if this code appears during a used-car inspection?
Arrange an independent professional pre-purchase inspection before committing. Request a complete scan, readiness status and diagnosis of the relevant system. Get written findings and a repair estimate; an unlit warning lamp does not replace inspection.
How much does a P0507 repair cost?
