1. Make sure your gas cap is sealing.
2. Inspect the evaporation system hoses and line that goes from the fuel tank to the evaporation cannister, which is probably in the engine compartment
3. Inspect the hose/line going from the evaporation cannister to the engine.

Replace any cracked or leaky hoses.

Had my Smart 4-2 mot'd Monday and it needed a suspension arm on the passenger side. This was done on Tuesday. Saturday morning the engine management light came on yet the car runs and sounds fine.

Very seldom does the check engine light being on affect the way the engine runs, so have it tested for the fault that turned the light on, It is called an OBD2 fault code test and is done with a code reader through the diagnostic data link under the dash.

I have Peugeot 207 gt cc, the depollution system fault sign keeps bleeping up and engine management light has come up! Cam sensors are fine, plugs are fine! Car is 58plate petrol!

You need to have a OBD2 fault code test performed to determine what codes are present in memory, based on that test you do the prescribed diagnostics testing.

Why does my check engine light keep coming on?

Your car computer runs a self diagnostic of all critical systems on your car at start-up and the check engine light has come on because it has determined that their is a problem within your car.

A qualified automotive technician will need to plug in a diagnostic tool to determine the code the car is transmitting. That code will tell them what the problem is. Continuing to ignore the light can eventually lead to a critical system break down of one or more components of the car so the diagnostic check needs to be done as soon as possible. Of course, with older cars this light could be coming on in error but your chancing it if you ignore the light.

My engine light was on, so i got a diagnostics done and it said the bank1 sensor 2 needed to be replaced. i Replaced the sensor but the engine light keeps coming back on after the part was replaced and...

no year. stated, sigh, nor country, sigh 2.
no DTC posted.!
post the DTC code, do not interpret it , state it. P0xxx?
flat out.
are there other codes? other stored or pending DTC codes?
there are many oxy codes, not stating the code is bad news.
each has a different reason, guessing is a fail.

btw , sensor 2 does not run the cars fuel mix. that be sensor 1.
btw, sensor 2, is rear of cat sensors.
this sensors purpose IS TO , warn of a dead CAT.

if the CAT is getting NAILED by rich fuel , the cat can be good
and the code P042x is one, that can be cause by other fueling issues. RICH. if rich (vastly) the cat can overheat. and fail that test. you need to post all facts, in my questions. first.

PO441 ,PO442 codes have to do wit the oxagen sensors, If there is a problem with both of them,Or your cat is pluged up ,The car will not run (Properly)

I have a 2004 Chrysler Pacifica and a diagnostic code of P0441 coming up on a reader. What does it represent and can I get the repair done myself?

P 0441 = Purge flow not detected.
Problem with "leakage detection pump" or purge valve. Blocked purge hose. Could also be caused by extremely low engine oil level.

The check engine light came on it seems to run fine the only other thing i noticed is the temp gauge runs up to 210 then comes back down,it only does that right after you start it then its fine

Check engine light can be any number of reasons, dirty air filter, need oil change, or more serious engine trouble. The temp gage issue is normal, this is the computer resetting itself. My car the fuel gage and temp gage do this...don't be alarmed. Take it to Advance Auto Parts and they can run a free engine diagnostics test on it to see which error code is tripping your check engine light.

Check Engine Light Keeps Coming on

I would almost guarantee it is your O2 sensor. You can confirm this by going to autozone and they will run a free diagnostic for you.
