When the "service engine soon" light comes on, it's throwing a code. There are numerous codes to features and devices that could be the problem. You will need to get the specific code by having the system read with a diagnostic code reader in order to find the specific problem area.

Hello,
The 'Check Engine' light comes on when there is an emmission problem..It could be as simple as a loose gas cap.,. Or it could be it needs oxygen sensors, catalyic converter, etc. If it went out, don't worry about it, unless it comes back on. If you want to know why it came on, get a "Peake" tester for about $100 - the fault is stored in the computer flash and you can find out. Plus the Peake will reset all computer functions, like service lights, etc...

Thank you!!!...

    IT could possibly be a P0440 (Evaporative Emission System) small leak/no flow condition..Which can be rectified by hooking up a ODB..Take the car to a service and ask him to Hook up ODB..that should solve your problem..

    Yeah fine may be you can take the car to the same mechanic and ask him to rectify it but he might charge you for sure!...Dont worry but your car will surely be back on Track and fine!!.. :)

This simply means that your service date is near.. This involves

1.) replacing the engine timing belt
2.) changing oil in engine and transmission,
3.) changing filters
4.) serviceing the fuel injection system,,

Basically a tuneup.
After its done, the mechanic will use a autodiagnostic tool to check for any error codes from sensors, investigate and correct the problems if any and then clear all error codes and reset the service counter. This is a saftey feature now standered in most cars to prevent damages to the vehicle and to insure its running propperly all the time. Noting to worry about unless you wait too long. If you do then

The cars computer will shut down the vehicle where it will become imnobile and noting can start it. There will be 2 ways to get it to move,

1. Call a wrecker
2.) get a mechaninc to clear the counter and fool the system into thinking it was surviced.

BTW AFTER THE CAR HAS BEEN SERVICED AND THE CODES CLEARED AND RESET, THE MECHANINC WILL NEED TO RETIME THE THROTTLE BODY, this is done by
1.) opening the driver door,
2.) disconnecting the negative battery pole
3.) pushing the axcellerator right down to the floor and holding it there while someone reconnects the battery pole
4.) starting the vechicle with the peddle right down and then slowel releasing ..

Thats about it.. No need to worry, just get the vehicle surviced.

    BTW failure to service may result in damages to the engine and transmission, if you need more details on this you may contact our dealer, normally its done with the car has a certin amount of milage to it.

  • Rishi Roshan Ali Jul 31, 2008

    Then the codes and counters were not reset, You will need to take it back and have them reset it. As this was part of the service package they will have to do it for free.,, Once the vehicle is functional without any seeming problems and this light it on, it mean you need to service the vehicle, especially the timing belt.

  • Rishi Roshan Ali Jul 31, 2008

    if it was a sensor ,,the bmw feature shyts the vehicle down. it isnt a code it just needs clearing and resetting.

    Check pin 5 for ground and 16 for battery voltage. Seehttp://www.auterraweb.com/obdiipinout.ht...



    Pin 5 was grounded, pin 16, however had no voltage. I took a closer
    look at some of the fuses test light and found that the fuse labeled
    "CIGAR" was blown in such a way that it was hard to see. I replaced it
    and was able to read the codes. Now I have to figure out what those
    mean:



    CODE #1: P1518 - PCM to TAC Module Serial Data Circut

    CODE #2: P0440 Evaporative Emission System

    CODE #3: P0440 (Pending) Evaporative Emission System



    FREEZE FRAME DATA FOR P1518:

    Fuel Sys 1 OL

    Fuel Sys 2 OL

    Calc Load (%) 0

    ETC (°F) 190

    STFT B1 (%) 0

    LTFT B1 (%) 0

    STFT B2 (%) 0

    LTFT B2 (%) 0

    MAP (in HG) 25.1

    Eng RPM 0

    Veh Speed 0

    MAF (lb/min) 0

    TPS (%) 15.2





    And yes, I have checked my gas cap! I'll be extra sure to make sure its
    on as tight as I can get it just to be sure. I have cleared the codes
    and will watch for the light again.

A service engine soon light that flashes generally results form an ignition problem with the engine. A service engine soon light that stays on constant results from an emission control system malfunction. A diagnostic scan from the local parts store can determine which emission system is faulty.

Service engine soon light


The service engine soon could be an indicator that you need to have minor maintenance done in the near future. I had a Grand Am that the service engine light would turn on when I was getting close to needing an oil change. You might check your owners manual for an exact reason as to why it turns on.

I have a 2001 Oldsmobile Alero. What does it mean when the anti brake light, service engine soon, and traction off light comes on at the same time?


I am assuming its not the service engine soon light it is probably the service vehicle soon light, There are 2 lights service vehicle soon upper left side, and service engine soon upper right side.

When all these come on at the same time it is the wheel bearing sensor. Usually the wheel bearing needs to be replaced which houses the sensor. A sure way to check is to press your sls button by your shifter and see if the light goes out, If it does not, u will need to have a wheel bearing put in.

1998 nissan altima dashboard display engine service soon


Hello and thank you for using FixYa!

The service engine soon light comes on when a fault is detected in the emission system. The service engine soon light is the same thing as a check engine light. A scan tool will be needed to get the code for the failure, so the proper repairs can be made.

Thanks Jay!
