P0507 on Chrysler by model: symptoms, diagnosis and fix
The Chrysler 200 experiences intermittent engine stalling at idle, particularly when decelerating to a stop or sitting at traffic lights. The electronic throttle body accumulates carbon buildup that restricts airflow at idle, and the throttle position sensor can drift out of calibration. The 2.4L 4-cylinder is most commonly affected but the 3.6L V6 is also susceptible. The stall often occurs without a check engine light, making diagnosis frustrating.
Common Symptoms
- Engine stalls when coming to a stop
- RPM drops very low then engine dies
- Rough or surging idle
- Stalling without a check engine light
- Engine restarts immediately after stalling
How to Fix
Clean the electronic throttle body with CRC throttle body cleaner — remove the air intake hose and spray the butterfly valve and bore while a helper opens the throttle plate. After cleaning, perform an idle relearn: key on (engine off) for 30 seconds, then start and let idle for 5 minutes without touching the gas pedal. If stalling persists, have the dealer reflash the PCM with the latest calibration and inspect the throttle body for TPS sensor failure. Replacement throttle body costs $200-$400.

Frequently asked questions
What does P0507 mean on a Chrysler?
P0507 stands for "Idle Air Control System RPM Higher Than Expected." This code means the engine is idling faster than the computer's target idle speed, typically by a set margin such as 200 RPM above commanded. The engine control module manages idle by metering a small amount of air around the throttle plate (via an idle air control valve or electronic throttle), and when it can't bring the RPM down to target it flags this code. The most common real cause is unmetered air sneaking into the intake — a vacuum leak — that the computer can't compensate for. It generally indicates extra air entering the engine or a problem with the idle/throttle control system. On Chrysler it is documented across 1 model: 200.
What are the most common causes of P0507?
The most common causes of P0507 are: Vacuum or intake air leak (hoses, gaskets, intake boot), Dirty or sticking throttle body or throttle plate, Faulty or stuck idle air control valve, Leaking intake manifold or throttle body gasket, Stuck-open PCV valve or cracked PCV hose, Dirty mass airflow sensor giving false readings, Failing throttle position sensor, Leaking brake booster or its vacuum hose. The specific cause varies by vehicle.
How much does it cost to fix P0507 on a Chrysler?
Published repair estimates on Chrysler range from $30 to $400 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
