While a check engine light is always an occasion to worry, diagnostic trouble code (DTC) P0507— Idle Control System RPM Higher than Expected—isn’t the worst error message you can receive. In this situation, your car’s engine is idling excessively above the normal revolutions per minute (RPM) rate. In most cars, normal engine idling is 600–800 RPMs but can reach 1,200 RPM in an older car. In addition, the engine in an aging vehicle may have higher RPMs at the start, which settles down after warming up.
While no check engine light should be ignored, code P0507 doesn’t require immediate and urgent action. On the seriousness scale, it’s classified as low severity. You can go about your daily activities but will want to get the problem addressed within a few weeks.
Until then, you’ll continue to encounter high engine idling that may be accompanied by rough engine operations and hard starts. It’s also not unusual for less-than-smooth transmission shifting. However, you’ll want to resolve the problems sooner rather than later if the symptoms include stalling to avoid unsafe driving conditions.
High idle speeds affect fuel economy and cause extra engine wear and tear, so allowing the issue to continue long-term can be costly. Continue reading to learn what triggers a P0507 code, typical repair costs, and the vehicles most likely to face this problem.
Possible Causes of P0507 and Their Repair Costs
As mentioned, code P0507 signals an engine idling above its normal RPM range. This can be caused by an imbalance in the air-fuel mixture or a problem with an electronic or mechanical system that regulates the engine.
Check out the FIXD article on the most common causes of check engine lights.
Review this table for a better understanding of the likely triggers of a P0507 code and average repair costs.
| Part To Repair | Part / DIY Price | Mechanic Total Cost |
| Vacuum Line | $50–$150 | $200–$300 |
| Throttle Body (cleaning) | $20–$40 | $150–$250 |
| Throttle Body (replacement) | $423–$525 | $509–$634 |
| Mass Air Flow Sensor (cleaning) | $20–$40 | $100–$200 |
| Mass Air Flow Sensor (replacement) | $40–$50 | $239–$346 |
| Idle Air Control Valve (cleaning) | $20–$40 | $150–$250 |
| Idle Air Control Valve (replacement) | $40–$160 | $213–$385 |
| Power Steering Pressure Switch | $50–$150 | $180–$300 |
While the cause of code P0507 varies, here are the most likely trouble spots and why.
| Parts that can cause P0507 | How it could cause P0507 |
| Vacuum Line | A leak in a vacuum line can introduce too much air into the air-fuel mixture, causing increased RPMs to keep the engine running. |
| Throttle Body | A dirty or defective throttle body affects the amount of air that enters the combustion chamber, resulting in an incorrect air-fuel ratio. |
| Mass Air Flow Sensor | A clogged or faulty mass air flow (MAF) sensor sends an incorrect reading to the engine control module (ECM), causing higher RPMs to counter this wrong information. |
| Idle Air Control Valve | The idle air control valve controls the oxygen flowing into the intake manifold, so a dirty or bad unit can impact |
| Power Steering Pressure Switch | If the ECM detects a drop in power steering pressure (determined by the power steering pressure switch), it will instruct the engine to increase RPMs to boost the pressure. A bad switch can send incorrect readings. |
Makes Commonly Affected By P0507
While FIXD sensor data shows that few makes are exempt from P0507 trouble codes, specific brands are more likely to encounter this problem than others. Moreover, certain models have a greater likelihood of P0507 codes among these more trouble-prone makes than others.
Leading this dubious list is Dodge, with the Grand Caravan being the worst offender. It’s joined by the RAM 1500 pickup and the Charger sedan. Technically, RAM is a separate brand, having been spun off from Dodge in 2009. But old habits are hard to break, as RAM trucks are often called Dodges.
Detroit is more represented on this unfortunate list, with Chevrolet taking second place. In particular, the Silverado 1500 has the most significant share of P0507 error codes among the Bow Tie brand. The Malibu and Impala round out Chevy’s top three.
Nissans are no strangers to error codes related to high-revving engines. In particular, the company’s stalwart sedan, the Altima, has a high incidence of code P0507. The Maxima and Murano also make the cut, but not at the level of the Altima.
The Focus has more P0507 codes than any other Ford vehicle. Meanwhile, the company’s longest-running nameplate, the Mustang, can claim second-place status for this warning message among all Blue Oval vehicles. The Ranger follows in third place.
Volkswagen completes the top five, with the Passat generating more P0507 codes than any other VW. Its smaller sibling, the Jetta, and the compact Tiguan crossover are also known for their abilities to generate this DTC.

How to Diagnose P0507 Causes
Although higher-than-normal RPMs may be present in your car, it’s best not to assume the cause even if a check engine light is active. Use an OBD-II scanner like the FIXD smartphone app with a plug-in sensor or a dedicated device to confirm that code P0507 is the culprit. The FIXD app shows the most common problem areas associated with the DTC, which may inspire the curious to explore under the hood.
If this is the case, you’ll need gloves, safety goggles, a flashlight, and a rag. A spray bottle with water will also come in handy; we’ll explain how to use this shortly.
Safety Essentials
Before exploring the source of a P0507 code, you’ll want to observe the following:
- Park on a level surface in a safe area
- Ensure the car is off and the parking brake is engaged
- Allow the engine to cool

Regular, diligent maintenance is the best way to prevent a check engine light from being triggered by code P0507. However, these steps should also include regularly inspecting the throttle body and MAF sensor for dirt and grime buildup, which can lead to high engine RPMs at idle and eventual component breakdown. Generally, high or low temperatures aren’t directly attributable to a P0507 code. However, extreme weather can lead to the deterioration of certain components—like air hoses and vacuum lines—which can cause a P0507 code. According to FIXD sensor data from 2023, the Altima has the highest number of P0507 incidents among all monitored Nissan models. In fact, the Altima has a much higher occurrence rating for this problem than the Maxima and Murano, the models with the next highest incident levels. A DIY approach to correcting a P0507 error code requires moderate skill. Someone who’s never spent much time under a hood may find replacing a vacuum line or cleaning a throttle body daunting. At the same time, an experienced DIYer will find these projects to be no-brainers. We’ve listed a few DIY activities around a P0507 code, assuming the amateur mechanic has an intermediate skill level. Above all, a DIYer must know their limits. Don’t proceed if there’s a risk of causing damage or injury. Proper air-fuel mixture is one vital element of a smooth-running engine. A vacuum leak creates an imbalance that can lead to a higher-revving engine and code P0507. The greatest challenge to fixing a vacuum leak is finding the problem. The water spray technique (see above) only goes so far and can require more sophisticated methods that are best left to experienced hands. While replacing some vacuum lines is relatively easy, a vacuum leak involving a gasket, intake manifold, or other components requires professional intervention. A replacement vacuum line will cost $50 to $150, depending on the vehicle and the component. The throttle body controls the air entering the intake manifold through a butterfly valve as part of the vehicle’s air intake system. This valve and the surrounding area can develop a cruddy, gummy build-up that impacts engine performance. Cleaning out the throttle body is relatively straightforward, but locating and opening the air duct may be intimidating for a first-timer. So, while the actual task of spraying the affected surfaces and wiping away the grime is simple, getting to that point requires a certain degree of familiarity. Expect to pay $20 to $40 for throttle body cleaner spray and supplies. The mass air flow (MAF) sensor measures the amount of air entering the engine, which determines how much fuel is sent into the combustion chamber. A dirty or defective MAF sensor affects this reading. Accessing the MAF sensor is uncomplicated in most cars, but the work requires a delicate touch and very specific steps if a replacement is involved. Expect to pay $20 to $40 for MAF sensor cleaner spray and supplies. A new MAF sensor costs $40 to $50. As mentioned, other problems can trigger a P0507 code. However, depending on the vehicle, dealing with an idle air control valve or power steering pressure switch may go beyond the DIY space. Accessing these parts can be challenging, and additional diagnostic steps may be required to confirm the problem. Remember, newer cars may still be under warranty, so check before attempting DIY repairs to potentially save money. FIXD sensor data gathered in 2023 shows the following vehicles are most likely to experience a DTC P0507.
