Take the vehicle to AutoZone or similar business that allows free use of their scanner. Read out any codes which should point to the problem area and maybe the problem component. Many items on the engine or exhaust can cause this warning. When fully repaired, use the scanner to turn off the light. Hope this helps!

What does po440 on a 2003 saturn vue mean with a service engine soon light on


That is a problem in the evaporative emission control system.
Could be anything causing it
Clogged filter in the charcoal canister
A leak in one of the vacuum lines
The purge valve not working,,,etc.
The best thing is to take it and have it checked out, they might have to do a smoke test to find the problem.
All they do is inject smoke into the system, if there is a leak the smoke will come out of it. All it takes is a pin hole in these emission systems to screw it all up.

I checked the codes and one comes up its po446. i dont under stand what it mean so i cant fix it to get the light to go out.


P0446 Evaporative Emission System Vent Control Circuit.
The following are descriptions of all Evaporative possible codes:

P0441 Evaporative Emission System Incorrect Purge Flow
P0442 Evaporative Emission System Leak Detected (small leak)
P0443 Evaporative Emission System Purge Control Valve Circuit
P0444 Evaporative Emission System Purge Control Valve Circuit Open
P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
P0446 Evaporative Emission System Vent Control Circuit
P0447 Evaporative Emission System Vent Control Circuit Open
P0448 Evaporative Emission System Vent Control Circuit Shorted
P0449 Evaporative Emission System Vent Valve/Solenoid Circuit
P0450 Evaporative Emission System Pressure Sensor/Switch
P0451 Evaporative Emission System Pressure Sensor/Switch Range/Performance
P0452 Evaporative Emission System Pressure Sensor/Switch Low
P0453 Evaporative Emission System Pressure Sensor/Switch High
P0454 Evaporative Emission System Pressure Sensor/Switch Intermittent
P0455 Evaporative Emission System Leak Detected (large leak)
P0456 Evaporative Emission System Leak Detected (very small leak)
P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)
P0458 Evaporative Emission System Purge Control Valve Circuit Low
P0459 Evaporative Emission System Purge Control Valve Circuit High
---
At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.

Emissions reset not it doesn't register for inspection


all of the tests have not run yet.. the mechanic that cleared the codes did not do you any favors. you must repair the problem causing the light to come on. you may need to keep driving it until a light comes on, and then a QUALIFIED mechanic can fix the cause of the light.

BMW 1999 318i eml light come on whilst driving. Car drives well but light still on. Any thoughts to why ?


The EML light will come on if you have an emissions fault , the car may drive ok but you may find you are using more fuel , it would be better to get the problem checked just to be on the safe side , regards mark.

Emmissions light has come on?


you need to get it scanned, i assume "emissions light" is your check engine light, or the "visit emissions workshop" message, which means, go to a shop and get it checked. The coolant disappearing means you probably have a leak. Another reason to check it,

Emission light comes on


it will not pass the test with the light on, and if u turn off the light they will know when they test it by testing/checking the system readiness function. Go to a Kragen or an Autozone they will run the test to see what trouble code has turned the light on, it is free, post the code back here. Oh have then reset the light after the test.
