The automatic gearbox has malfunctioned in some way, making it impossible for the computer to determine whether it is in gear or not, which prevents the engine from starting. To get it diagnosed, you must take your automobile to a dealership.

AT CHECK: What Does That Mean?
The other day, as I was using the cruise control in my 2001 Infiniti QX4, the cruise suddenly cut out and the vehicle failed to change into fourth gear. I turned it back on after switching it off, waited a short while, and then noticed that something lit up with the words “AT CHECK.” Could someone please help me?
Your trans code is present. Have the dealer check it out. You might perform easy tasks like checking the fluid level while the car is in park. Make sure the level is appropriate. If everything appears good, you should go to the dealer so you don’t get locked up. When the cruise stopped, was the O/D light flashing? That is unmistakably evidence of a trans control issue. Possibly the dash-mounted speed sensor or the entire unified meter.
Hello, this is my first post. just checking to see if anyone had solid knowledge on this. The search function on this forum was useless to me.
When I tried to turn the automobile on, it just sputtered. I gave it another shot, same result. There was no real cold outside. never before occurred. Despite having over 100,000 miles on it, the engine is in excellent condition. When I googled the “AT CHECK” engine light, I found the image that is linked below. According to the light’s description, it is a “Continuously Variable Transmission, CVT check warning light” (if so equipped).
Additionally, the light has stopped coming on, and the OBDII scanner I used returned no codes.
I then drove another vehicle to perform errands. Later, my father claimed he checked it out and it started without a hitch. I went to check it out, and it also began perfectly. I did read the following in answer to a problem with the “AT LIght” that was similar to mine, but I wanted to double-check with you guys because I’ve never heard of this.

When you turn the key off and on again after the trans sends the motor into fail safe mode due to a power loss, the trans resumes operation until it encounters that failure once more. Slipping transmission or an internal problem may require a total rebuild if the car is acting as you describe.
He asked when the transmission fluid and filter had last been updated. You should have already had the transmission serviced given that you have surpassed 100k kilometers. To determine whether the fluid is good, you should check the level and color. The vehicle’s starting problems could be caused by something entirely different. I couldn’t find anything about beginning problems from the URL you gave at the end of your first post; all I could find was information about how the transmission was causing the vehicle to perform poorly on the road. The next time you see the “AT CHECK” light, hopefully you can use an OBDII scanner to receive a proper code and a better understanding of what is wrong with your car.
Sorry, it was completed at the dealership at least two hours ago. Just out of curiosity, how frequently do you recommend they be completed? The AT indication light barely momentarily illuminated; I guess I’ll just keep it nearby. Otherwise, it might have been an isolated incident.
The conventional A/T (Automatic Transmission) in my 2003 utilizes NISSAN Matic “D” fluid, however i’ve read that the A/T CVT fluid should last a lot longer or never need to be changed. I’m not sure which recent Altima models were the first to use the more sophisticated A/T CVT, but in any case, everything should be included in that service manual.

The rationale for a CVT check light won’t apply to your car. Your vehicle lacks a CVT.
When the automobile starts and runs without issue and the transmission feels as like it is shifting smoothly, the suggestion of a transmission overhaul seems very dramatic. It makes great logic to mention the crank sensor. The starting point is also the least expensive.
Why does my Nissan Altima’s check engine light come on?
Your 2020 Nissan Altima’s check engine light will begin to blink if there is an urgent need for repair, so you should bring your Nissan in right away. Usually, a serious engine misfire that causes unburned fuel to leak into the exhaust system is indicated by this blinking light.
The check oil light is there on a Nissan Altima, right?
When the engine oil pressure is low, this warning light will come on to let the driver know. If this light comes on, stop in a safe location right away, and turn off the engine.
What does Nissan Altima maintenance entail?
The Maintenance Tire Light: What Does It Mean? When your Nissan’s tire maintenance light comes on, it’s time to rotate the tires as part of your normal maintenance program. (This warning light has nothing to do with tire pressure.) Thankfully, the tire maintenance light is not a cause for concern.

A Nissan Altima does it notify you when to replace the oil?
One of the most fundamental and important maintenance for your car is an oil change. Normally, synthetic oil needs to be changed every 7,500 to 10,000 miles. For traditional oil, Nissan recommends having your 2022 Nissan Altima’s oil and filter replaced every 3,000 to 5,000 miles.
What does maintenance for Nissan mean?
Based on the oil that Nissan engineers who created your engine prescribe, the Nissan Maintenance Minder determines your vehicle’s requirements. The frequency of oil changes won’t increase with the usage of synthetic oil.
Why is the engine light on in my Nissan?
Flashing Nissan Check Engine Light There are numerous other strong causes for a Check Engine Light, including a filthy mass airflow sensor, a damaged oxygen sensor, a problem with the fuel injection system, a bad head gasket, or defective spark plugs, to mention a few.
What causes the check engine light to appear most frequently?
The oxygen sensor is the same way. This important component measures the amount of unburned oxygen present in your car’s exhaust, and if there is too little or too much, it may harm other engine components. Every time an oxygen sensor fails, a check engine light will come on. In fact, it’s among the most frequent causes of a check engine light appearing while you’re operating your car.
Is it legal to drive with the check engine light on?
Don’t freak out if the check engine light comes on while you’re driving! Keep an eye out to observe if the car is driving in any unusual ways. The question “Can you drive a car with the engine light on?” may be on your mind. The performance of the vehicle and the underlying cause of the check engine light’s lighting will determine whether it is safe to continue driving. Simply remember to get your automobile checked as soon as you can when the light comes on. Don’t put off necessary engine maintenance!
You can keep operating the vehicle if nothing seems unusual. Anything from a bad oxygen sensor to a poor MAF sensor could be the root of the problem. It can also indicate that your catalytic converter has stopped functioning.

Why does the maintenance oil and filter message on my car?
Why does that matter? The foundation of the majority of planned maintenance plans is the oil and filter change. Any planned maintenance program or maintenance reminder system should take this into consideration because the oil needs to be replaced more frequently than any other consumable.
Why is the tire maintenance light on?
The TPMS (Tire Pressure Monitoring System) is designed to notify you when a tire’s pressure is too low and may result in hazardous driving situations. If the indicator is on, your tires may not be properly inflated, which might result in premature tire wear and even tire failure. It’s critical to comprehend the value of appropriate tire inflation and how TPMS can prevent a potentially hazardous situation.
Both excessive and inadequate tire inflation can result in early tread deterioration and potential tire failure. Increased traction, early wear, and an inability to withstand impact from the road can all be effects of overinflation. The middle of the tread on tires with excessive air pressure may prematurely wear out. Underinflation, on the other hand, results in slow tire reaction, lower fuel economy, excessive heat buildup, and tire overload. The shoulders or tread edges of a tire that is underinflated will prematurely wear out on both sides.
Finding the TPMS indicator on your dashboard is straightforward if this is your first time hearing about tire pressure sensors. It is a light that has a horseshoe form with an exclamation point in the middle.
How can I tell if I need to change my oil?
Your car will be the first to let you know if there is a problem with your oil. Check the dipstick to see what’s going on because your car’s oil change light will come on if there isn’t enough oil in the system. The check engine light may come on in more serious circumstances. This is your vehicle’s way of alerting you when conditions have gotten so severe that the engine could suffer damage from malfunctioning components or a lack of lubrication.
What kind of sounds does an oil-needed car make?
The main function of engine oil is lubrication. Moving elements inside the engine do not receive the lubrication they require when there is not enough oil. This enables them to come into direct contact with one another, which may sound like light tapping or knocking.
If I add oil, will my car start?
Being unable to start your car is never enjoyable. Will adding oil, however, help a car start? Check out the details below to see if this is a reasonable choice.
The possibility exists that the engine won’t start if the oil level is low. Try starting the engine after adding the appropriate amount of oil. Your car might not be starting for another reason if the engine oil level is normal.
Oil is an engine’s lifeblood; it keeps all the moving parts lubricated and ensures that the engine runs smoothly. This article will cover the various potential causes of your automobile not starting as well as why your engine won’t start without oil.
