    THe SES or Service Engine Soon Light , serves many purposes, as I discovered.it can be caused by a loose gas cap, a faulty sensor such as air flow , or any number of problems, do not ignore this as it can cause you a lot more money in the future, as I ended up paying over $500 for servicing my car.

How do you turn off or reset the "Service Engine Soon " light off without taking my Infinity I35 to dealer. Trying to avoid $200.00 dealer charge!

Check and make sure your gas cap is on properly first.
Have you noticed any differences in the way your car is
running? Most of the check engine light complaints from
our customers at the dealership turns out to be an improperly
installed gas cap. You might have to take a number of
trips to and from the store before you check engine light will
go off, if it was the gas cap or you can have a service dept.
turn it off for you.

On the Mercedes C-240 the oil sencor light came on with the A service oil change .I had the oil changed and now the oil level light comes on. And this is on a 2005 C-240 4-matic .


Could be the person who changed it never ran the motor and then topped it off once the filter was full. Have you checked the oil level after you let the car sit overnight to make sure the oil level is on full? I would say it could be a bad oil level sensor, except that the coincidence of coinciding with an oil change is too obvious.

Service engine soon light came on, changed oil and of course changed filters checked gas cap all good any ideas


There are really too many things to list that can cause the service engine soon light to come on. I suggest you have your mechanic scan your vehicle to see what codes are present to cause the light to come on.

How it reset service engine light


Is it the "oil change req." light? Your owners manual will have the process for reseting the oil change light.
If it is "service engine soon" light, the vehicle will need to be scanned with a professional scanner.

2001 cheve venture (service engine soon) trouble light on


If ou fixed whatever happened during the oil change, the light will cycle off after about 3 drive cycles.

The check enine light just tells you that you are not meeting emissions right now. Only be concerned if it's flashing. That means you are sending unburned fuel to your catalytic converter whih will overheat and self destruct.

Look for a vacuum hose disconnected and check all the onnections to sensors such as, vehcile speed control sensor, mass air flow sensor, crankshaft position sensor, camshaft poition sensor, throttle position sensor, etc. Good luck.
