SOURCE: 1997 Honda Civic emission control system problem?

Yes the problem is effecting the emissions controls. Sounds like the timing if off. Take the vehicle to you local Auto Parts Store and most will scan the ECU for fault codes. This code will help you to figure out the problem.

SOURCE: 2003 audi a4 1.8t ECU/emission control system warning light flash

No I am a mechanic at Audi. The problem is that the the air flow to the central tappets may be causing the air flow sensor to trip and that is why. Try putting a small amount of WD40 into the petrol and that will work, its a very common problem.

Service engine soon light


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 light and no power


Hi there:
First, it is normal for the check engine light to come on momentarily when you turn on the ignition switch and then go out. If it stays on, then you have a stored code that indicates a malfunction of some kind in your engine or transmission control systems.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

I suggest visit some Autozone or AutoShop with OBD Scanner Reader in order to scanning the module to know exactly wat fault code is stored there; note this code number for additional details.

Hope this guide 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.
