What does a check engine light looks light on a 2001 ford winstar?
On a 2001 Ford Windstar the check engine light looks like a picture of an engine
just to the right and a little bit lower than the ( O/D OFF light )
Is there a way to reset ck engine light in 2002 infinity QX4 using the ignition?
I have not found one. There once was a post online stating it could be done by pressing and depressing the gas peddal and turning the ignition off and on in the right sequence. Tried it several times and it didn't work. AutoZone sometimes will do it for free. No harm in asking.
(Alternate method) This will work if there only was a temporary problem like a loose gas cap or whatever item that caused the problem was corrected:
1. Lift Hood and set brake for security.
2. Disconnect both positive and negative cables to the battery using a #10 open and closed end box wrench.
3. Since you did that you may as well clean the terminals (optional).
4. Reconnect the cables to the battery.
Re-start vehicle. Your clock and radio settings will need to be reset.
This method should clear only erroneous check engine lights. If light stayed on there is a larger issue that needs repair before engine or smog control damage. If the check engine light went out but after driving for 10 to 20 minutes the light came back on you can try the method one more time. If the light goes back on after that then there is a problem that will requires repair.
Many part stores or auto repair facilities will use their portable hand held computer to diagnose the problem. Depending upon the auto repair facility they may not charge you a fee but hope to get your business. It takes all of 10 minutes to do in the parking lot.
How do you reset the service light on a c200 Mercedes?

- 1 can be addressed by sometimes tapping on the air flow box (little black box on top of the assembly - off of the air filter) and seeing if that loosens the dirt. If not, you need to get a special fit hex-star bit to unscrew the box and open it up.
- 3 is the most expensive, as oxygen sensors cost approx. $70 apiece to replace. If you're going to do one, might as well do both. This should be your last resort though. (Find out exactly which codes you get before investing the money into oxygen sensors.)
- 4 air flow assemblies cost about $85 and are relatively easy to put on.

What does Fuel Fail 46 VCM code mean on a 1993 Jaguar XJ6?
Idle speed control valve coil 1 fault. Off voltage not less than 0.85 volts or on voltage not exceeding 12.25 volts.
'check gauges' means one of your dash warning gauges went beyond normal paramaters, alerting a problem... my guess is- it's your oil pressure gauge....CHECK YOUR OIL level... if the level is low, when the truck leans (as when you exit an off ramp) the oil pressure will drop.
What does it mean when your EML light stays lit on a 1989 BMW 750il?
Take the car to a BMW dealer - there's a problem with the electronic throttle control.
What could be wrong when the check indicator light is on in a Hyundai Accent?
I had my check indicator light on and the first time is was a sensor that controlled the amount of fuel going to the engine, it failed and was starving the engine of fuel. I had to have the sensor replaced (expensive)
Second time it was the Oxygen sensor that goes into the flexible exhaust pipe. The pipe had developed a leak and was causing the sensor to go off. I had the pipe replaced and reset the sensor by disconnecting the battery for an hour or two. It seemed to do the trick but the exhaust guy said the sensor is barely holding in there and will eventually fail.
The MIL (malfunction indicator lamp/check engine light) can be set by anything from a loose gas cap to an engine perfomance issue. If the light is steadily illuminated it can be driven but should be checked out sooner than later. If light is flashing do not drive the vehicle.
What causes an engine misfire Lexus es 300 1999 The code came back as misfires pls. help?
my Lexus rx300 misfired as well and i took it to the mechanic and it was the fuel injectors that where dirty because of bad gas
Try resetting the fuel cut off switch and see if the engine will start
Why does the engine fan stay on all the time on your 1995 Buick LeSabre?
Also, consider whether or not you have the AC turned on.
Probably either the relay sticking or a bad (or unplugged) engine coolant temperature sensor.
Go to auto zone and have the codes read for free. They will also look up the meaning of the code for you, but be careful about taking their advice on how to fix the problem. If you have an older Focus, buy a code reader on eBay for approx. $50.00 USD. (OBD-II) because you will need it a lot. The Check Engine light is always related to something in the emissions control system, e.g., a bad sensor, a leaky vacuum hose, etc. Other auto parts stores may also read the codes from the computer for free. Do not pay a mechanic just to read the code. You can try clearing the code from the computer and waiting to see if it comes back. The computer connection port is below the steering wheel, to the left, behind a little plastic cover.
AnswerAutozone is NOT the answer.Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self tests the computer runs the car through a drive cycle, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. OR hook up a scanner that is capable of clearing codes, and hope that none are still active.
AnswerMine was a oxygen sensorWhy does the ABS light on a Chrysler Pacifica keep coming on?
This is a very common problem with Pacificas. I own one myself, a 2005, and my ABS is almost always on. It came on 3 mths after I bought it, after my warranty ran out. If you research it, it's usually something to do with speed censors going out, or brake sensors. Usually when you have them replaced, they'll go back out again in a months time, and they're costly too! I wish I could just get rid of my car altogether! For now though, I went to www.nhtsa.gov, the National Highway Traffic Administration and sent in a complaint so they can research the problem and possibly put a recall on it, since it's such a popular issue with these cars. If you don't mind, please go and put in your own complaint. Maybe if we get enough of these, they'll recall them, and we won't have to pay for their mistakes in building these cars. Thank you & good luck!
Additional information: I have a 2006 Pacifica with the exact same problem. We were lucky & bought an extended warranty on ours, so we haven't had to pay for the "repairs" to this issue. However, just to let you know, no matter how many sensors or whatnot they've replaced, the problem just keeps coming back over and again. The service manager at the Chrysler dealership told me that the Chrysler engineers are aware of the problem, have no idea what's causing it or how to fix it.
I'm considering demanding Chrysler take the vehicle back. I can't be sure that the brakes/ABS don't have a problem, and I have a long commute to work on busy roads. The dealership said might be worth a try, they don't know if Chrysler has done this in the past (bought back) or not. If I am successful with that, I'll post.
How do you turn off or reset the check fuel cap light on a 2007 Honda Accord?
CHECK FUEL CAP, TIGHTEN FUEL CAP MESSAGES
This article applies to 05-06 Accords, 06 Civics, 05-06 CRV's 05-06 Elements, 05-06 Odysseys, 05-06 Pilots, 06 Ridgelines and 06 S2000s.
"If a vehicle's fuel fill cap is loose or missing, and the ECM/PCM detects an EVAP system leak when it runs the EVAP monitor, the CHECK FUEL CAP message appears on the information display when the engine is started. A temporary DTC is also stored in the ECM/PCM's memory. If this happens, there's really no need for the owner to bring the vehicle in for service. All he or she has to do is shut off the engine and make sure the fuel fill cap is in place and it's properly tightened.
Although the owner can cycle the message from the display with the reset button, the temporary DTC that's setting the message is still there. This means the message never really goes away. It can be cycled back with the reset button and it comes on again if the ignition switch is cycled or the engine is restarted. This message keeps coming back until the EVAP monitor runs again and it finds no EVAP system leak. This could take several days, even weeks, depending on how often the vehicle is driven.
If, when the next EVAP monitor runs, the cap wasn't tightened or there's another EVAP system leak detected, the MIL comes on and the message goes off. A permanent DTC is now stored in the ECM/PCM's memory. If the owner now tightens the cap, the MIL should go off after the next EVAP monitor run, yet this could still take days or weeks. If the MIL is still on after that monitor run, then it's time to bring the vehicle in for service.
If the vehicle comes into your shop with the fuel cap messaage or the MIL on. make sure the fuel fill cap is in place and properly tightened. Record the DTC, then clear it with the HDS and run the EVAP system function test. If there's still a problem, press on with normal troubleshooting."

How do you resent the check engine light on 2000 Toyota Celica?
Resent?? Trust me.. it's easy.. we all resent the check engine light.. lol!!
However.. asumming you meant "reSET" the light.. you need to use a trouble code reader that has the capability to "erase" trouble codes once it reads them. You can purchase these online or at most any auto parts store starting at about $69.00 up to $400.00. For a 2000 model Celica, you will need one that is "OBD2"(I recommend the Innova 3100 ... $88.00 on Amazon.com).
BE ADVISED... simply erasing the code and resetting the light does NOT fix the problem of why it came on in the first place and there is a 99.99% chance that the light will come back on within a few miles of driving until the cause of the light coming on is resolved.
Hope this helped.

If you mean the brake lights are staying on, then the switch at thte pedal is sticking. Could be dirty or need adjusted. Switch is under dash at the pedal.
