will the p0597 code cause the car to fail emissions inspection in North Carolina?
My car has 60000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. The code P0597 is for the thermostat heater control circuit. This means that the thermostat is electronically controlled in your vehicle. To see why this code is on, check the following:
A loose or corroded connector on the thermostat
A coolant leak in the cooling system – make sure that all connections are tight
The thermostat could have failed – stuck open or partially open
There could be a short in the wiring harness between the computer and thermostat
The ECM (computer) has failed – Only in the event that all areas have been check and are all functional
Once the engine light is off and the engine is running correctly, you would be able to retest your vehicle at the emissions in your state. If you need further assistance with your check engine light on, then seek out a professional, such as one from Your Mechanic, to help you.

However, that doesn`t mean it`s a good idea to keep driving it around. If you`re experiencing issues leading to a P0597 code, then that means your vehicle is at high risk for overheating, which can seriously damage your engine and lead to a much more expensive fix with significantly more long-term damage.
What Are the Symptoms of P0597? There are typically not many noticeable symptoms of this issue. The primary indicator is that the check engine light will illuminate. Depending on what position the thermostat was in at the time of failure, the engine may run either hot or cold.
What the P0597 code means. If a PCM (Powertrain Control Module) stores this code, it`s because the engine`s thermostat is experiencing an issue with the control voltage. The control circuit is most likely either open or short.
Can I Still Drive with a Bad Thermostat? The easy answer to this question is no. While your car may be physically able to move and get you from Point A to Point B, you will want to refrain from operating your vehicle. This can lead to more parts of your vehicle being damaged, especially if the engine is overheating.
Driving with a malfunctioning heater control valve can present major issues. Since it is a part of your vehicle`s climate control system, it may cause problems in keeping your windows clear which can affect your visibility.
Checking For the Signs of a Bad Thermostat
Look to see if the coolant is swirling/flowing immediately — that means the thermostat`s stuck open. If the coolant doesn`t flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it`s hot, the thermostat`s likely stuck closed.
Can I drive my car with the thermostat missing? Your car would not necessarily overheat since the fluid would be constantly flowing through the coolant system. It would however take longer to warm up and during long periods without a break it could overheat, but yes you can run a car without a thermostat in it.
A thermostat stuck in the open position constantly pushes coolant into the engine and causes a lower operating temperature. Your temperature gauge will show a needle that barely increases or remains at the lowest setting.
How serious is the P0599 code? While the vehicle may show no symptoms at all when the P0599 code is stored, this code does represent a serious issue that could lead to major drivability issues later. A vehicle with this code stored in the PCM should be repaired as soon as possible.

Why does the emission inspection failed almost every time its due for DMV inspection?
ANSWER : Hi there:
Honestly, the lack of consistent driving could be the reason why you have frequent emissions issues. If the car does not run frequently and have an opportunity to circulate built up carbon deposits on the inside of the fuel injection system or exhaust system, failed emissions testing may be the result. The best thing to do is to drive your vehicle once or twice per week about a month or so before your emissions testing is needed. Also, it’s a good idea to replace air filters frequently before emissions testing is completed. This article is a good one that helps many car owners learn what they can do to help improve emissions testing.
Can i retrieve CEL code from car … forgot what code it hade in my car .. put headgasket sealer and i erase the code ..
ANSWER : Once a trouble code is erased, it cannot be retrieved. The engine controller does not have a "recycle bin" like they have on Windows. If the car still has a problem, the code will come back up after some driving. However, the controller will not turn on the CEL until it has seen the malfunction on two separate "trips." A "trip" is a driving cycle where the car is started cold, driven until it is fully warm and through a certain number of accelerations, and shut down. So you might not see the CEL for a couple of days. As for the "head gasket sealer," I wouldn’t hold out too much hope of that solving a problem. At the very best it might put off the symptoms for a short while. If you need help interpreting codes that come up, or solving a head gasket issue, contact Your Mechanic. They can send a technician to your home or office to read the codes on your car and help you decide what to do.
I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
I have failed smog 2 times this past year (2016) for high NOx at low speeds but passed at higher speeds.
ANSWER : Hi there. The issue that you are having is the purge valve on the fuel system is not functioning correctly and needs check and possibly replaced. The code P0600 is referring that the dash is not communicating to the ECM (computer). Check the wiring harness to the computer from the dash and see if anything is loose or damaged. If you need further assistance with your emission, then seek out a professional, such as one from Your Mechanic, to help you.
Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.
Will a bad battery cause my car to shut off and my EPS light to come on? What would cause it to come on?
ANSWER : Hi there. This is a serious battery problem if the battery is now swollen and has no power. There has been an obviously internal fault. This will cause the vehicle to power down and the EPS light to come on as well. The EPS light is the warning indicator for the electric power steering. I strongly suggest having a qualified technician do a diagnostic inspection to determine the root cause of the battery behavior and if there has been any compromise to the other electrical systems. It may only be a failed battery. If you’d like to have this checked, YourMechanic has several technicians available that can assist you with an electrical inspection and can replace your battery as needed.
Failed emissions after P0505 code… Considering options
ANSWER : The mechanic that checked your vehicle is giving you a possible fix by cleaning the throttle body of built up carbon. This may help with the idle and P0505 code, and for passing the emissions test. The throttle body is controlled by an electrical motor as part of the throttle body. If cleaning does not clear the problem, then the throttle body may need to be replaced. I recommend having a certified technician give your car a second opinion after diagnosing your Check Engine Light code.
