P0507 is a fairly typical OBDII trouble code. It is typically triggered when the engine idle speed is 200 rpm or more over the predetermined limit set by the manufacturer. It is a generic code, which means that it has the same for the Nissan Maxima as any other vehicle.
P0507 Symptoms
Unlike many OBDII trouble codes, P0507 will typically be noticeable to you when driving. Here are the typical symptoms for the Maxima:
- Service Engine Soon Light– The reason why you are here.
- Faster Idle Speed– Assuming that the code has been thrown due to a legitimate issue, you should notice the engine running faster when not pushing the gas.
- Thud Going Into Drive– Transmissions really don’t like to shift from park to drive at an RPM higher than idle. It is common to feel the whole vehicle jerk when put into gear with P0507.
- Vehicle Takes off Faster– With the engine idling higher, people report feeling the vehicle take off when releasing the brake pedal. This can make driving more dangerous.
Nissan Maxima P0507 Causes and Diagnosis
There are a lot of potential causes to P0507. While the code specifically mentions the “Idle Air Control System”, it would be a mistake to just go ahead and replace it without a little due diligence. The Idle Air Control Valve is often not the cause of the code.
Here are some of the most common causes of P0507 in the Nissan Maxima, as well as waist to troubleshoot them. Keep in mind that there are differences in model years. It would be a good idea to start by looking for a vacuum leak and move forward from there.
Vacuum Leak
A leaking vacuum system will often cause the Maxima to idle higher. When the vacuum system leaks, it allows extra air to enter into the combustion chamber. This air allows for a slightly higher combustion, increases the RPM and throws the code.

A vacuum leak can come from bad vacuum hose, the intake manifold, EGR System, or about anywhere else that air flows through. It’s not hard to find a vacuum leak though. Use the resources above and you’ll find it in no time.

Idle Air Control Valve
Most modern fuel injected engines are equipped with an idle air control valve. Not all of them are though. If you have determined that you don’t have a vacuum leak, the IAC is a great second place to troubleshoot P0507.

Throttle Body
A throttle body opens and closes millions of times in the life of a vehicle. All of the air that passes through it can slowly cause it to collect grime. This grime can change the idle characteristics of the vehicle. When dirty, you’ll often feel the vehicle almost stall before the computer compensates and opens it a little more.
Alternatively, if the throttle body has been damaged, it may not be properly regulating air flow, and the code may be thrown.

Conclusion
P0507 is a serious issue. Due to the unsafe nature of driving with an engine that is revving higher than it’s supposed to, we recommend having your Maxima serviced as soon as possible. Good luck!
Diagnose and fix Nisan Versa Hesitation, P0705
Nissan has issued a service bulletin NTB15-082 to address a Nisan Versa Hesitation, P0705 trouble code on the vehicles listed below. The NTB15-082 describes a situation where the driver feels hesitation during acceleration. When scanned, the computer reveals a P0705 Transmission Range Sensor A Circuit (PRNDL) code stored.

Most likely cause of Nissan Versa hesitation during acceleration and P0705 trouble code
The NTB15-082 advises NOT to automatically replace the transmission range selector as your first choice. Instead, Nissan has identified a corroded circuit board in the rear tail lamp assembly as the most likely cause of the hesitation during acceleration and the P0705 trouble code.
Nissan recommends checking for water intrusion into either or both of the rear tail lamp assemblies. If you see any signs of water or moisture, check the circuit boards and light bulb sockets for corrosion. If you find corrosion, replace the tail lamp assemblies, clear the trouble code and see if the hesitation goes away

Why it’s probably not the transmission range switch
See the transmission range switch wiring diagram to the right. Power flows to the Transmission range switch (TRS) from Fuse 49 and a connection at the transmission control module (TCM). As you switch between gears the +12v battery power flows back to the TCM to tell it which gear you’ve chosen. However, since the TRS also supplies power to the backup lamp circuit, the TCM is expecting to see a large voltage drop on the Reverse signal control wire, i.e. a reading slightly above 0 volts. All other lights are controlled by the body control module (BCM), but the backup lights are powered directly from the TRS. If there’s corrosion in the tail light assemblies, the TCM will see higher voltage on the reverse signal line and set a P0705 trouble code.
