What does a blinking check engine light indicate where to start looking for an engine miss?
== == You need a diagnostic download tool that will tell you the actual stored memory codes, which is the first step in fixing the problem. These tools are about $130 USD to buy, or you can go a licensed gagage and have the technician do it, for a price. By having the test done by a tech you will not be guessing as to what the problem is, and throwing money at it trying to get it fixed. Spend the money for the test, and know for sure what is wrong with the car. Then have it fixed and be happy. Many autoparts stores now offer to read those codes for free. Of course they're hoping that you'll buy any needed parts from them. I use Autozone for this virtually every time to find out what the car is complaining about. I agree using Auto zone or Advanced Auto. They read and cleared my code for free. CEL stayed on all the time on my 2001 Windstar. Turned out to be the EGR sensor I replaced.
Where is the plug to get code for check engine light 1998 vw cabrio?
To the right of the rear window defroster button, behind a plastic cover. Just pop it off with a flat head screw driver.
On my 1998 Cabrio, I found it to the right of the ash tray. Remove ash tray then slide the cover to the immediate right of the ash tray to the left to reveal the OBDII connector.
Could be that after you started it then turned it off then restarted it that you've reset the codes and fooled the Computer... you need to have the codes run on the car to see what the problem really is, i dont think its anything major since the car seems to be running good.
This is happening to my car too and I had the codes run and they did a scope on my engine and a bunch of other things and they could not find anything wrong. They said to be careful and monitor the temperature because it did occassionally show it was over heating but other than that not to worry. It has now also stopped over heating. Mine is a 94 but the problem sounds the same.
How to solve a code 35 in a 1993 GMC 1500 with a 4.3 engine?
Before going any further verify that none of the spark plug wires are old or damaged or located near the wire to the knock sensor. Wrapping them in aluminum foil can also eliminate this problem. If this doesn't help, follow normal diagnostic procedure.
according to my information a code 35 on 1993 gmc is an idle air control system problem/idle speed actuator.

How do you get the check engine light off on a 1996 Nissan Sentra?
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 test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist.
What does the light PGE-FI mean on a Honda dashboard?
Never heard of PGE-FI. Are you sure it is not PGM-FI which stands for Programmed Fuel Injection.
How do you get rid of the engine check light on a 1997 Toyota Camry CE?
I've heard that disconnecting the battery for an hour or so works. Or turning the ignition on and off (without starting the car) repeatedly.
The starter solenoid is most likely bad if it will not crank over If it cranks over most likely crank sensor is bad how can you just say most likely the crank sensor? how the hell do you know it could be anything
What are the causes of the service engine soon light on 2002 gmc Yukon?
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
Where is the check engine light in the cluster of a 1997 Ford F-150?
If your gauge cluster has a tachometer:
The "Check engine" light is under the tachometer just below the "1000."
If your gauge cluster does not have a tachometer:
The "Check engine" light is below the fuel gauge, just to the left of the high-beam headlight indicator.
How do you reset the check engine light on a 1997 Mazda 626?
"Disconnect the negative terminal and push brake pedal for 30 seconds" worked great! One note: You must use actual key to unlock doors after battery disconnect to reset car alarm so car will start.
I recomend getting the car checked out by a professional. And you never unhook the positive battery cable first, you always do the negative firstl. And sometimes when you do this it erases the computers memory. so take to a professional.
If you HAVE TO, disconnect the negative battery terminal. Put your foot on the brake pedal for 30+ seconds.
I tried the previous answer of removing the negative battery cable, and holding the brake pedal for 30 seconds and it WORKED!!! Just got back from the emissions test, and passed. THANKS!!!
I got check engine light problem just happened few hours ago, my car is 1999 Mazda 626 ES, and I tried the previous answer of above- revmoving the negative cable as well. It REALLY WORKS. It saved my time & money ^^
[Apr 27, 2008]Just applied this method "disconnect the negative battery terminal. Put your foot on the brake pedal for 30+ seconds.", it just worked perfectly. Save me lots of worries and trouble to send the car to mechanics. Thanks so much to the one who posted this method.i just used removed the negative battery and stepped on the brake for 30 seconds on my 2000 626 es and it worked! saved $80
Just did wt u said and it really works...thanks a million
Same thing works on a 2006 MX 5 Miata....light came on due to loose gas cap and I sure did not want to pay the dealer to reset the dang thing.....Advisable to check out why you have the light at AutoZone or most other parts houses before you reset the light.
a car scanner can help you.
Why would the check engine light on a 1995 Chevy Cavalier keep flashing?
this happens to my 94 and after looking all over to find out why i traced it to the starter switch was broken and stuck between the ignition and off position just enough to start it but not enouph let the light go out
I would not think so but I have learned that nothing is impossible. P0040 is not an O2 sensor code, it is a EVAP system leak. A loose gas cap will set this code for sure as the code indicates a leak in the EVAP system. If it does not come back on then forget it. If it does replace the gas car first and clear the codes. If it comes back on then check the EVAP system hoses for cuts or leaks, check the purge valve. If none of these are leaking you need to see a pro and have a smoke test run. These can be very tricky to find at times.
Does the check engine light have anything to do with the transmission?
quite possibly....the check engine light is a universal signal saying "something is wrong". Take the car to auto zone and have them use the hand held diagnostic. Once used, the diagnostic will pull up a code from the engine's computer that the auto zone employee can pull up. Once the code is looked up for that particular vehicle, itll tell you what the light came on for.
Why does 99 mercury grand marquis run rough check engine light on?
The check engine light indicates that the computer has detected a "fault". Use a code scanner to find out what the computer has detected, that is PROBABLY the reason the engine is running poorly.

What causes check engine light to come on in a 1999 grand marquis?
It can be any number of things, from a loose gas cap to any of the systems and sensors on the engine that are monitored by the computer. You need to have the codes pulled up with a code scanner
What could be the cause of misfiring of Cylinder 1 of 2003 Mitsubishi Eclipse?
Answer
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another.
Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
Answer
this could be anything to do with the cylinder on your car. The plug, the wire, the cap, or the coil (whichever you have.) your best bet is to do a tune up on thecar and do all the plugs, wires, cap, and rotor. if you have a coil pack, try to change those. this is all i can say for now. if that doesn't work, ask the question again and give a little more detail on how the car is acting.
Technically speaking, cylinders do not "misfire": the spark plug causes a spark which causes the fuel to ignite which moves the cylinder, so it is the spark plug that may misfire. Given that, motor vehicle spark plugs may misfire due to any of a number of reasons, including watered-down or low-grade fuel, old and/or dirty oil, fouled spark plugs, clogged cylinders, insufficient oxygen to the plugs, poorly aligned cylinders, et al.
