Check Engine Light

Well i would think it was an electrical failure of some sort poor connection of sensor/s maybe if you disconnect battery earth lead hold down horn and switch lights and anything else on in your car hold down horn for minimum 2minutes then reconnect battery this will wipe all of ur ecus memory so if it continues to blink after this then look for loose wiring or corroded or poor connections to one of your sensors

important if u do this u may need to get ur radio code as ull be locked out and reset ur clock

It's your 02 sensor.

There is a problem with the SRS (Supplemental Restraint System) air bags. Due to the dangers of working on this system only have this repaired by a qualified professional.

The check engine light does not come on when an oil change is due. The check engine light is for an emissions related failure. It is reset with a scan tool after the fault is repaired.

It is on because the ECU has detected a problem with the emissions system. Have the system scanned with an OBD2 scan tool to retrieve the code that has been set. This code will tell you what part of the system is being effected. Not necessarily the defective part but what part is being effected.

Absolutely yes.

mine did the same thing i canged the plugs and two coil packs if you have an advance auto near by they will plug it in and tell you the problem if check engine lite comes on like mine was missing cylinder 4 & 6. like I said i replaced the plugs first and it was still missing and then i replaced two coil packs which are about 50.00 a piece. mine a 98 grand marquis 146000 miles on it

first off buy a repair manual for like $20. There's a two prong blue plug that hangs under the dash on the passengers side. Turn ur key to the on position then use a paper clip to use as a jumper to the two prong holes on that plug and watch the flashes of your check engine light. it will flash so many times then pause and flash again so many times. the amount of flashes tells u the first digit then pauses and then gives u the second digit of the engine code. so u'll have a blink with a pause then four more blinks, that means your engine code would be 14. A dealer or repair manual will tell you what that code means.

Disconnect the red terminal on battery and let it sit for 15-30 minutes, reconnect the battery and check engine light should be off because the computer has been reset.

How do you reset the "check engine soon" light on a 2005 Ford Explorer? I usually disconnect the battery.. for couple of minutes and reconnect the same. But I advise you to have this checked with the ford dealers or anyone with a computer console as the above is just a temporary solution. Its better to spend a couple of $ resolving a problem then $$$$ repenting over it !!!!

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. Yes, depending on the cause, you could do damage.

Yes

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. It is emission related. We just found out that the check engine light on our 1993 Toyota Pickup is due to a bad "knock sensor".

If you are referring to the check engine light, then the computer has detected a problem with the emissions system. Use an OBD2 scan tool to find the fault code and after repairing the fault, use the same tool to reset the light. If you don't have access to an OBD2 scan tool, than you can just disconnect the negative terminal on the battery for about ten minutes. The downside to doing this is you will have to reset the clock and radio stations on your radio.

What do you mean by check oil light? If the oil light is on it means the oil pressure is low and stop the engine immediately and check the oil level. Now if you are referring to the maintenance required light then without the make, model, & year of the vehicle I cannot answer your question. All I can say is read you owners manual. On most newer GM cars and trucks you turn the key on and push the gas pedal to the floor 3 times, turn off.

I do not ever recall seeing this question!

Be forewarned though, the base diagnostic trouble code (DTC) descriptions are very short & cryptic.

But it's a good start to identifying the components/sensors/readings that are involved.

Possibly. What an exhaust leak will do is KILL you. Either from the Carbon Monoxide you inhale while driving or the wreck you are going to have when it puts you to sleep. Get the exhaust leak fixed ASAP.

Repairing the fault which is causing the check engine light is the recommended way to go about doing this.

it is under the housing where the lower radiator hose hooks to the engine

Not likely but it is possible.

Disconnect the Negative(black) terminal from the battery for a minute then reconnetc. If this does not work, go to Autozone/Checkers/Pep Boys and plug in their code reader and clear the codes.

Any leak will change the way the engine breathes. Any change can change the air/fuel mixture. If it changes enough it can cause damage.

P1259 refers to Vtec system malfunction.
