How do you reset the check engine light 1994 Chrysler Concorde?
After fixing the cause of the problem. you clear code with a scan tool, or by unhooking the battery.
How can you manually turn off your service engine light?
Go to your local auto parts place and have them check the code you (should be no charge). After they check the code as the associate to turn off the light for you. This will only be temporary unless you fix the problem so the light won't come on again.
The other way is to unhook the battery for at least 10 seconds... this should reset the light. However, like before, this is only temporary- unless you fix the cause, the light will come back on within a day or 2 of driving
What are the possible causes for a Mustang's check engine light being on?
oxygen sensors. could be the culprit . There are too many things that it could be. Take your car to autozone and they will run a scanner. I bought one from them for about $30.

try unplugging the battery for a while. that may turn it off IF you fixed the problem that turned it on.
How do you fix the malfunction check light on 2002 Honda?

On my Chevy truck it idles high when its low on antifreeze but if its not that more than likely its usually a vacuum line loose or cracked. good luck.
What would cause a 1995 GMC Jimmy to idle and run rough and the check engine light come on?
Mid 90's Jimmy's have issues with cracked blocks, at transmissions, the front differencial, as well as the oil: pan, filter, pump, and gasket. It is very possible that the block is cracked.
AnswerIt could also be carbon in the EGR valve... AnswerEarly 90's Jimmys has a multiport fuel injection system which used a fuel regulator and delivery system inside the intake maniford. The Central Port Injector(CPI or Spider) has had a tendency to leak from the regulator putting excess fuel into one side of the intake manifold. The single O2 sensor reading the combined exhaust trys to lean the mixture by shortening up the "on" time for all of the injectors which leans out the other bank of cylinders. In essence you have three cylinders running rich, three running lean. Not the best situation for a stable idle.The indication of this is that one side of the intake manifold will be relatively clean(usually a yellowish brown)from being cleaned by the gasolene, and the other side dirty from the blow-by products from the crankcase vent. Check out: http://www.asashop.org/autoinc/feb2000/techtotech.htmfor a expert diagnosis from an ASE Certified Tech with lots of pictures of what I was trying to explain. Look for "Jimmy CPI Unit" on EBay, they have some of the newer modified units for fairly cheap ($200), their not hard to change, just be careful not to get any dirt into the injectors when you remove the poppet valves at the end of each feed tube. That's about it if it's the CPI, hope it helps.94 AnswerI have gone through 2 EGR ValvesA few times a friend even cleaned one to get it going, It worked for a while but eventually failed. Answerits prolly the egr valve a piece of carbon is prolly holdin it open mine used to do that but i got a gasket made by timeco an it has a screen that stops the carbon from buildin up AnswerIf the check engine light is on, get an obd2 scanner and check out what code is stored in the computer. The scanner will tell you what codes showed up even if the light is now off. The code should tell you exactly what is wrong without guessing.Reasons for check engine light on a 1997 gran am gt?
if you take the car to autozone, they should be able to check it for you with a scanner. if not, then you should take it to a Pontiac or any GM dealership.
i had the codes checked in my 97 grand am gt 2.4 and they told me it was one or all of the following.
1. oxygen sensor (o2) defective
a. poor connection @ the o2 sensor
b. check circuit-fuse
2. knock sensor
a. defective
b. check connector and wiring sensor
c. engine mechanical condition- knock or rattle in engine
d. low fuel- pressure
3. coolant temp always low
a. check coolant level
b. thermostat defective
c. ect (engine coolant temprature) sensor defective
4. evap (evaporation emission system) small leak no/ flow condition
a. defective or loose fuel cap
b. evap canister or hose cracked-not connected
c. purge or vent solenoid defective
d. vacuum leak at engine
hope this helps you out
This indicates the need for the computer codes to be read from the computer. This will lead a technician to the cause for the light to be lit, which may be related to the ABS system being nonfunctional, which is most likely related to the loss of Vehicle Speed Sensor input signals to both the Computer and the instrument panel. Should all of this be tied together as interrelated issues, finding the cause for the interruption of the VSS signal and effecting repairs could alleviate all the problems. NOTE: An "ABS" or "VSS" code is no indication that these components are faulty. The code serves to inform a technician that the values from these sensors is out-of-range for the conditions surrounding vehicle operation at the time the code is set. This may be due to a loss of signal because a wire has broken, or the computer ground is lost, or system voltage has fallen below minimum levels for readings to be obtained, or the alternator has shorted a diode and is producing AC current along the computer's inputs, or a spark plug wire is resting upon an input lead and inducing stray RF signals onto the line that the computer cannot interpret. All this and much more is possible--- which makes necessary the services of a trained professional who can troubleshoot the system in a methodical way to arrive at the root of the problem, and fix it. Any other approach involves guesswork and a waste of time and money, leading to unnecessary anxt and frustration.
possible blown head gasket, and a fuel leak /// unless is a diesel engine, in which case it probably running too rich, possible turbo, possible valve timing, possible intercooler
After retrieving obd codes which one do you fix first?
The one with the smallest number. ie: p0200 before p1500
What if service engine light is blinking on a Chevy silverado?
Normally a flashing check engine light means you have a misfire. Do not ignore this as an engine misfire will damage the O2 sensor and the catalytic converter which are very expensive to replace. Have this repaired immediately.
What is diagnostic trouble code p0650 mean?
Trouble code P0650 means:Malfunction indicator lamp control circuit malfunction
Truck has check oil pressure light on and a trail of oil on ground after driving?
Obviously your oil has been leaking out. Check the oil level and fill to specs. Also you need to fix the oil leak.
How do you turn off check engine light on a Ford F-250 1997?
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
First thing to do is have the diagnostic trouble codes (DTC) read from the computer. They will provide the first 'lead' in your investigation.
From there you'll be able to focus on which part of the engine to test, repair, clean, and maybe replace.

How do you reset a check engine light on a 1996 Toyota Camry LE?
First, if it is something like a loose gas cap, just tighten it and it will reset itself in the next 100 miles or so. If it is something else, like a leaky gas cap it will never reset. But to reset the OnBoardDiagnostic (OBD)Computer... Go to eBay and search "obdII" and buy one, they run about $50.00 including shipping. There are two types, ISO for Chrysler and some Japanese, and the other one for all the others like Ford and GM. There are several that are both, that is the kind you want. Be sure to email the eBay seller and ask if it is used with your year and model. (1996 was a changeover year for OBDII technology, so this advice may not apply to everybody--but the dealer service guy can tell you over the phone--ask him if it is OBDII compliant.) When you get it, you just plug it in and let it cycle 4 or 5 times and it resets everything. You then have to drive your car for 50 to 100 miles for the onboard computer to test everything, and in the meantime your car will fail smog checks because it has no history in the computer and the smog test procedure demands a history even if there is no pollution. Cut and Paste http://search.ebay.com/OBDII for a list of them for sale on eBay. Most units come with a list of generic fault codes so you can tell what the problem is, this could be very helpful.
it might go away by it self but you can disconnect the battrey for one min then reconnect it and the if it comes back on then you will have to have it checked it might not come back right away it might take a day befor you know and i f it goes away then it is fine
Answerno.on most computer conttroled cars you can disconnect the battery for 10 seconds and it should go away. but it will turn back on if somthings stillwrong in the system.
