The easiest thing to do to have that checked is go to autozone, checker or someplace like that. They test for free and can tell you what the light means. Then we can figure out what is wrong.

SOURCE: service engine light is on in my 2004 Buick LaSabre

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

SOURCE: 2003 Buick Regal Service Engine Soon light.

The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.

SOURCE: check engine light

Hi

This is unlikely to be related to a simple coolant flush or oil change. Obviously you should check that all your fluid levels are correct as a first step in the process. It is possible that a connection to a sensor on the engine has been disturbed during this work which can then set off the EML so check all visible electrical connections on the engine first.

If there is nothing evident from this check you need to have the car put on a scanner at a dealers to identify the trouble codes stored in the cars ECU. The stored codes will point towards a diagnoses. Often a bad sensor is the cause of a problem such as this.

Hope this helps. Please do rate this answer. Many Thanks.

SOURCE: Service engine soon light comes on my 2002 Buick

the service engine light means that the computer has detected that there is something wrong. it doesn't mean that it is anything serious. it could be something very simple. if you want to find out what it is exactly and avoid repair shop costs, take it to auto zone or another parts store. most of them have scanners that they will hook up and tell you why the light is on without charge.

Car lost power uphill with air on and was hard to start once. blue exhaust smoke when reved up otherwise runs good


Blue smoke is not good!! Piston rings are bad or valves. On a Mercedes it will cost you more than the car is worth at this point. Unless you have a sentimental attachment to the car and really really want to keep it., I would get rid of it. 123,000 mile is a great life for a 1989.

If there is a lot of ice then I would think that the coolant was iced up and the engine overheated as stated . The engine light is there to let you know that something drastic is about to happen to the engine and you should stop immediately , check the oil level and coolant level before driving any distance.

  • You can turn this light off real quick by following these steps.
  1. Turn the key to ACC.
  2. Press the gas pedal down all the was three times in fairly rapid succession.
  3. The service engine soon light will begin to blink and then disappear.
  4. Turn the key to off.
  5. now start your truck.
  6. The light will now be off.
  • This should be done after every oil change.
  • All the light means is that the PCM has indicated that you have driven the required miles for an oil change. A reminder light if you will.

Whath does "service engine soonmeans"


SERVICE ENGINE SOON and SERVICE ENGINE NOW are 2 amber warning lights pertaining to the vehicles computers.SERVICE SOON advises you of a problem, although not an emergency should be attended to promptly. Your technician can trace the problem by accessing fault codes through the climate control panel. SERVICE NOW indicates a more severe problem which will most likely precipitate a failure / breakdown. The CHANGE OIL LIGHT indicates by time and mileage is a separate light.
