Check Engine Light

the light is a warning to you that something is wrong and your engine is not operating correctly and needs to be serviced soon. Most times there is a part of the emissions systems that set it off, like a bad sensor somewhere. You will need to get the CODES read. The codes are then converted to a diagnostic problem and then the parts of that system need to be analyzed to see which one is not operating. I will ask this....did you just recently get gas? You must turn the gas 3 clicks when you put it back on to make sure the correct pressure is in the gas tank otherwise you will get a check engine light. So go check your gas cap and if it is tight.........then you will need to take your car to a place liek Autozone and they will put a diagnostic scan tool on your car usually under the dash under the steering column and pull your codes. From there it is up to you where you decide to get it fixed, either by yourself or a garage. By the way after you tighten the gas cap you will need to drive some miles AND go thru a few stop and start cycles with the engine befoer the service engine light goes out if it was a gas cap issue. The light will not automatically turn off after you tighten the cap.

check the oil in engine to see if it has coolant in it

white smoke is caused by coolant or water burning with fuel
sounds like you have a blown head gasket
i would also find a better mechanic

Either you will pay a dealership or car mechanic to look up the code, have them fix your car, and have them clear the code or you can fix it yourself, and disconnect the ground on the battery for about a minute and hook it back up. Should clear the code.

This sounds like your wheel hubs need replaced. These are where the sensors for ABS and Traction control are located. I'm very surprised a dealer would not be able to find this. It is possible another sensor is bad, but this is the same problem I had with my 2001 Alero.

If you have service engine light on, trac. off light and the ABS light on the same time, you may be able to get it fixed my reprogramming the power control module (with updated software calibration). Mine was fixed for free at a dealer under a recall campaign when GM called me yesterday.

You may have knocked off a wire when you reconnected the starter wire, Check the wire going to the O2 sensor. if this isn't it take it to a shop and have them scan the ecm. It could be a flewk.good luck....Michael

Hey Mona==Get it checked out before you ruin the engine. If the gauge is gound into the red there is a problem somewhere. If you ignore it you can ruin the engine which is megabucks. GoodluckJoe

It may not have anything to do with the oil. Go to Auto Zone and have the codes read and repaire them. GoodluckJoe

You have a sensor or something wrong in your engine peformance. You need to use a scan tool to scan your PCM or you can use a paper clip to retrieve trouble codes for your car. You have ALDL on 1994 saturns. Assembly line Diagnostic link. Under your dash about where your left knee is when your driving is your ALDL. just take a paper clip and jump the B lead with the A lead. then turn your key to the on position.(don't start just turn key on)your service engine soon light should start to blink the trouble codes stored on your PCM. invest in a manual for your car it will explain how to read and understand the codes. The codes will help pinpoint the problem you are having. The internet has alot of information on this topic too.

Take it to the dealer. They have check out charts. This happened to me in a 96 Monte Carlo. The dealer did not have time to look at it - we were on a road trip out of town - but suggested it might be the key. Ours has the chip in it - maybe your does, too? He said it might be going bad. At any rate, we changed to the spare and the light went out and stayed out. That was over a year ago, so sounds like he was right!

The check engine light codes have to be read and removed with a scanner on anything after '96.Auto Zone will do it free.GoodluckJoe To reset the "check engine" light, simply disconnect the battery for a moment and it will go out. This worked for me on my 98 Ranger. try checking the co2 sensor. A sure fire method, if you can access the fault codes, is to remove the jumper wire while the codes are displaying. 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. Pukenstein@aol.com Unless it is a hard code...OBDII hard codes will not reset simply by fixing the problem..they have to be reset with an OBDII scanner Advance Auto Parts has em too

YES-IF IT has a vaccume booster & not Hydro or air brakes

Usally U turn the key on without starting & push the gas pedal down 3 times within 5 seconds.

My 1995 buick regal (3.8) has developed a problem when started.The oil level monitoring warning light stays on after the engine is running. I can shut off the motor and do a restart and the light will stay off,but every time the vehicle sits for any period of time with the motor off I go thru the same process again (light on at start up/turn off and restart and the light stays off)The oil level is up to par and the filter is clean and new. Any suggestions would be appreciated. Thanks! Faulty oil pressure switch would be my guess, same thing with my Previa. Replace the cheap switch and see if it is a more expensive problem.

If your check engine light is blinking that means an engine

cylinder misfire has been detected . You can drive it in for

repair , just avoid any rapid aceleration or deceleration

because you can damage the catalytic converter

Check engine light off, codes cleared; cold start.

-warm up engine 5 minutes (or until closed loop is reached--5 min is usually plenty)

-drive (w/ steady throttle) at a steady speed between 40 and 60 mph for 8 min

-stop and idle 3 min

-drive (w/ steady throttle) at a speed above 20 mph for 2 min

-turn key off, leave off 10 min

timing belt may have snapped

replace temp sensor it give no falt code just a problem

The EPC light came on today on a 2001 Seat Ibiza, along with the car's lock suddenly locking. After 3 or 4 efforts, we figured that the problem was solved unlocking the car using the key while the engine was on (the electronics on the car always blocked when the EPC came on). After that the EPC light switched off. I hope you can solve the problem this way.

Hi! #85 is an 'immobilizer' code. Most likely triggered by a missing/wrong chip in a car key (spare key - with no chip?). The code reader in the steering column is anable to recognize the key.

yes you can get this code, code p0455 is a large evap leak detected or no purge flow detected. A loose cap could create a large leak, so this could be the problem. However most loose gas caps will give you a small leak detected code.

is the cutoff switch a normally open or normally closed switch ? If it a normally closed switch as it should be then the switch will need to activate with the ignition in order to supply fuel. There could be a problem with the fuel cutoff relay or a fuse. Also if you are using a non factory key then this might also happen.

A Fiat dealer can give you an owner's manual. The owners manual should outline what each warning light indicates and its function.

You need an OBDII reader, I got mine at Auto Zone (can't think of the brand right now, but it's orange and was about $150), I've seen them for less, though and they work on all OBDII cars. Follow the instructions, write down the code incase it keeps returning, then erase the code and the light goes out. Good luck!

You can also try disconnecting the battery for about 20 minutes and then reconnecting it. It should clear it out. It worked for me. However I would go to Auto Zone first and atleast have them check the code. They will do it for free and at least if it comes on again you will know if it is the same problem.

I did the battery thing after having it checked at Auto zone and it cost me nothing. I then went and passed my emisions test.

where is the bank 1/sensor 2 O2 sensor on a dodge caravan...to the rear of the catalitic converter or to the engine (front) side of the converter?

we have a eng code 128s 370 02 we have a eng code 128s 370 02 we have a eng code 128s 370 02
