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.

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.

They will be able to tell you what your automobile is detecting as wrong with that error code.

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?
