Malfunction indicator light is on - states emissions problems
This light came on recently & I am taking it to Dealership, but was curious what the issues could be, as I don't want to be ripped off and they tell me all kinds of things are wrong-- its 2009-- Sx4-- 43,000 miles-- I still have a warranty, but need some info on this so they don't try to cheat me. I am 70 yrs. old & they see an old lady who knows nothing about the car. What can you tell me please ?

Re: malfunction indicator light is on - states emissions...
It should not be a big deal. The emissions controls on cars are so the fuel tank vapors do not escape into the air, but are sent by hoses to a charcoal canister that stores the fumes until they can be sent into the engine to be burned-when the car is running. It is somewhat complicated, with some electrical controllers that are commanded when to open to allow the vapors to be routed into the engine. All of this is done by the engine computer. The computer has a self-monitoring capability to watch the emission controls. When a fault is detected, the MIL light will be turned on, and a code for the problem will be stored. I should add that sometimes it is only a loose fuel filler cap, or a cap that is not vented properly.
Let the dealer check the codes and see what they say.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need. goodluck!
It sounds like you need a new fuel filter. if that is to dirty, it wont allow the correct amount of full to be pushed to the engine. try changing that or using a Fuel treatment in the meantime. Hope this helps :)

MIL is your malfunction indicator lamp, (check engine light)
CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer
check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.
It sounds like your engine is going into the 'limp home' mode, indicating there is a significant emissions equipment malfunction. Is the 'check engine' light on? You can take the car to a decent Auto Parts Store (O'reilly, Autozone,etc) and they will scan for the error code and reset the 'light' and get the car out of 'limp home' if the fault was intermittent. If the light comes back on, the malfunction has to be repaired. Literally dozens of minor malfunctions will cause this. The Federal Emissions Standard laws REQUIRE the 'limp home' mode when the malfunction will cause a significant increase in emissions. The problem could be a loose gas cap or loose vacuum line etc. MAJOR component failures are rare.
I have a 2009 Suzuki SX 4 - 43,000 miles-- Malfunction Indicator Light appears on dash-- in Manual, it states that there is a Problem with the Emissions-- taking it to Dealer BUT need some info for me SO they don't try to rip me off. Do you have any clue on what it could be? And, if it is EMISSIONS-- what charges should be? I am 70 yrs. old & don't want to get ripped off.. This is what the Manual is telling me. Can you help me and answer this question PLEASE !
The evaporative leak detection diagnostic strategy is based on applying a vacuum to the EVAP system and monitoring the vacuum decay rate. The VCM monitors the vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid turn ON, allowing the engine vacuum to draw a small vacuum on the entire evaporative emission system. If a sufficient vacuum level cannot be achieved, a large leak or an EVAP system malfunction is indicated.
The following conditions can cause this problem: * A disconnected or malfunctioning fuel tank pressure sensor * A missing, malfunctioning, improperly installed, or loose fuel cap * A disconnected, damaged, pinched, or blocked EVAP purge line * A disconnected or damaged EVAP vent hose * A disconnected, damaged, pinched, or blocked fuel tank vapor line * A disconnected or malfunctioning EVAP purge solenoid * A disconnected or malfunctioning EVAP vent solenoid * An open ignition feed circuit to the EVAP vent or purge solenoid * A damaged EVAP canister * A leaking fuel sender assembly O-ring * A leaking fuel tank or fuel filler neck
MIL stands for Malfunction Indicating Light. It is also commonly known as the "check engine light" on other cars. This light coming on indicates that the on board diagnostic function of the car's computer has detected a fault or faults in the circuits that it monitors. This system is designed to alert you to problems that will affect the efficiency and emissions of the powertrain as well as other problems in other systems. These faults are recorded and kept in memory. It takes a code reader to read out these Diagnostic Trouble Codes or DTC's. Major auto parts stores will generally gladly help you by attaching a code reader to your car and getting the code(s). With this information, you can get a better idea of the actual problem and may be able to prevent the problem from becoming worse. Also, if the MIL light is on, you will not be able to pass an emissions test should your state/county require one.
To know what it exactly is, you need a code scanner hooked to it.
If there is an autozone near you, go there, tell them the engine light is on and you need the code, takes about 30 seconds. They don't charge, where other places do. Without that code you'll be replacing things you don't need to. There is other sensors in the emission system other than the 02 sensors.
