Something is amiss when the check engine and service engine soon lights come on. Depending on the make and model of your car, you’ll see a different icon. It could be something minor, like a loose gas cap, or it could be something more significant, like a problem with the fuel system. When the light is on, you should bring your car in as soon as possible to get it checked.
A serious problem may be present if the service engine soon or check engine light is flashing. An engine misfire that causes the issue could harm the catalytic converters. It is highly advised that you have your car serviced right away if your check engine light is blinking.

What the Service Engine Soon Light Means
The check engine light and the service engine soon light are frequently confused. The check engine light serves as an alert to potential problems with your emissions or exhaust systems. A loose gas cap or more serious concerns, including a potential engine failure, may cause the service engine soon light to illuminate.
Unstable Gas Cap
A loose gas cap is one of the main causes of the “service engine soon” light coming on in your car. If the cap was not tightly reinstalled after the gas tank was filled, it may fall loose soon after.
The “service engine soon” indicator turns on when the cap comes loose after a specified amount of time.
This is made possible by the engine control module (ECM), whose main duty is to guarantee that your car runs as efficiently as possible. The ECM controls your car’s emissions and checks for any irregularities in the air-fuel mixture.
It first pinpoints the precise issue before conducting an internal test. When that occurs, you can either buy an OBD II scanner and perform it yourself, or you can visit your local service center for assistance in clearing the memory.
Service Engine Soon Light – Diagnosis for the Nissan Sentra
The service engine soon light on your Nissan Sentra is there to let you know that a problem has been found with the car. OBDII codes, which are easily accessible through a decent code scanner, are used by all automobiles manufactured in 1996 or later. A service engine soon light that is flashing indicates an urgent situation.
You must read these trouble codes if the service engine soon light is on to determine what is wrong with your Sentra. Even so, the existence of an engine issue is not always indicated by the trouble codes. The gearbox, ABS, oxygen sensors, etc. can be at fault.
Suitable Services
Hello there The SES light typically signifies that a long-term maintenance item needs to be addressed (i.e. fuel filter, oxygen sensors, catalytic converter, etc.). Before completing repairs, whether the Check Engine light is on or not, check for error codes. I advise getting a check engine service from a skilled mobile technician, like one from YourMechanic, who will visit your home or business, identify the issue, and provide an exact damage assessment and repair cost estimate.

m Wayne Powell An emission-related error may be the cause of the SES light being on. If you follow the directions in your handbook or those found at the links below, you can get the codes without leaving your car because it can figure out why the engine light is on. After you have obtained the code(s), the first link can inform you of their identity.
Procedure for ECM diagnostics and reset:
– After three seconds, turn the ignition key to the ON position. (Never start the vehicle.)
– In less than five seconds, fully depress and release the accelerator pedal five times.
– Hold off for exactly seven seconds. Until the SES light flashes, depress the accelerator pedal completely for ten seconds.
– Let go of the gas pedal, then begin counting the flashes to get the four-digit trouble code.
The first digit of the code is indicated by long flashes (0.6 seconds); record the first digit by counting the blinks from one to nine. Zero is shown by ten blinks.
The following three numbers are presented one after the other in the same order, but with faster blinks (0.3 seconds) and a 1.0-second break in between each digit.
Use the links below for further explanation if necessary. Some auto parts retailers, like as Pepboys, Nappa, Advanced Auto Parts, etc., also provide free code reading services. These men are often quite competent and can direct you to the problem. Good fortune.
Given that the car senses a problem, this is a common error. A handheld computer can be plugged into the automobile at the majority of auto parts retailers (Autozone, Advanced Auto, O’Reilley’s, etc.) to verify the specific problem code that is turning on the service engine soon light. They will be able to tell you what your automobile is detecting as wrong with that error code.
Agreed. However, in addition to the “check engine” and “service engine” lights, many cars also include an additional indication light for oil that flashes.
What does it imply when you reset the ecm according to the instructions above and receive the code yet the “Srvc. Eng. Soon” light doesn’t blink as it should? I drive a Nissan Sentra from 2002. I repeated the instructions four times, with the same outcome each time.
Since I performed a multiple pedal ECU reset, my 2002 Xtrail has been unable to start for nearly four months. The code 1123 indicates that the fuel pump is operating, but there are no sparks, and the injection system appears to be operating without a computer signal. Does anyone know how to remedy this?
What does “service engine soon” imply on my car?
The service engine soon light may just signify that you are a week or so past the next scheduled oil change for your automobile, depending on the sort of vehicle you drive. Maybe it’s not that urgent. Have the car’s oil level checked as soon as you can because it could also signify that it has critically fallen.
If the service engine soon indicator is on, should I be concerned?
Yes, on many different car models, a low oil level will result in the service engine soon light appearing on your dashboard. It can also indicate that there are other low fluid levels or other issues with the car. However, you should start with checking the oil level because it is rather simple to do so.

My 2013 Astra J SRi Petrol 1600cc keeps entering the limp mode. When this happens, I stop, turn off the engine, walk away for about 10 seconds, and then restart the vehicle. When I go outside again, it comes on again after a few kilometers.
An Altima from 2011 belongs to me. I examined it after the service engine lights illuminated. My code is P0101, which stands for airflow meters. I changed the airflow meter and turned the light back on. About 200 miles into the trip, the light turned back on. In slow traffic, I have observed that the idle is not smooth. I double-checked, and the p0101 code was still present. Why might this be? Thanks.
Hello, I have a 2009 Opel Corsa D 1.4. The car had a major service, and everything was well until the engine light and service light started flashing alternately.
My 2008 Nissan Quest’s check engine light came on after the mechanics completely replaced my exhaust system and determined it was an air sensor. It came back on five minutes after I left the garage, so they replaced the air sensor once more. They reset the code numerous times, but the light continues to come on and stay on.
They don’t appear to be aware of the root cause.
What might it be that my 2002 Ford Explorer shakes while I’m stopped at a stop sign and occasionally when I’m driving? Additionally, my service engine soon light is on. Why am I still experiencing that problem when my father just replaced the coil pageage and the spark plugs?
Regularly maintained Northstar engine from a 1999 Cadillac STS. Plugs were changed around 9 years ago at 90,000 miles along with a tune-up. 115,000 miles as of today. Authentic plug wires. The service engine soon light just turned on. Back when the light initially turned on, I replaced the gas cap over the fire. cap removed. Reapply it and tighten the cap. Light remains on. Suggestions?

How is a service engine soon light checked?
The service engine soon light indicates that your engine needs servicing and should be done as soon as possible. It doesn’t imply that the engine has malfunctioned or even that a meltdown is about to happen. It does, however, imply that you should schedule a visit with your mechanic as soon as possible to identify the cause of the issue and get the car fixed, if required.
If your service engine soon light illuminates while you are driving, you should stop as soon as you can to assess the condition and do a few quick tests. It’s possible that the issue is as straightforward as a missing or improperly-fitting gas cap because the sensors that activate the service engine soon light are frequently triggered by an issue with the emission control system.
As soon as you are off the road safely, thoroughly inspect the gas cap to make sure it is securely fastened. The emission sensors and the service engine soon light may be activated if the gas cap is not correctly sealed.
You may also experience issues with your most recent gas fill-up, which will turn on the service engine soon light. It is a fantastic spot to start your research if you recently purchased gas and then suddenly noticed that your service engine soon light is on.
Start by inquiring if there have been any new issues with the service station staff. There’s a good likelihood that other vehicles were also impacted if there was water or other pollution in the gas.
Try driving until you exhaust a couple of gallons of gas before topping off the tank with fresh fuel from a different service station if the automobile appears to be operating normally. You should schedule an appointment with your mechanic and have the vehicle checked out straight away if the vehicle’s performance has been affected.
The oxygen sensor, a mechanism that measures the manner in which unburned oxygen is released into the atmosphere, is among other issues that could turn on the service engine soon light. Ignoring a malfunctioning oxygen sensor might cost you hundreds of dollars in damage to your catalytic converter. That is just another justification for having a competent mechanic examine the service engine soon light as soon as feasible.
Having said that, if the service engine soon light is on solid and not flashing, you can generally drive safely while it is on. If your service engine light is on and flashing, you should stop right away, make a roadside assistance contact, and arrange to have your car towed to the shop.
Any dash light that comes on might be unsettling, but one with the term “engine” in the title can be extremely unsettling. However, you can react more correctly and make a wise and informed decision after you are aware of what the service engine light does and what it actually implies.
