Check Engine Light

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle.

Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.

If your 95 is anything like my 01 Seville the Crankshaft sensor(s) 2 of them are found by going to the front of the car, crawing or sliding under where the radiator is and a little to the passage side by the oil filter there are 2 of them an A and a B senor on the 2001 the service manager told me where they were and I when to the library found a service manaual and xeroxed the page that had a picture of it other wise I would not have known hope this helps cost of my sensors where around 160 each

It is loacated under the passanger side seat.

The obdII connection is on the right side of the steering column mounted on the edge of the the lower dash panel.

Really need to know year and model, but most new Lexus models have about 25miles of fuel left in the tank after reading 0 miles left. This is done to prevent damage to the fuel pump.

Take it to a repair shop or somewhere that can read the computer, a check engine light can mean a lot of things it is very broad, reading the computer can help you narrow down what is wrong with it.

After several weeks of intermittend codes or P0455, suddenly I could no longer fill the gas tank easily. I had to let gas trickle in. Dealer mechanic said fuel tank would not pressure test so they replaced my locking gas cap that I used for three years, then it pressure tested okay. They also replace the charcoal cannister ($152) and the cannister control valve (solenoid) for another $40.

I bench tested the cannister and found no leaks or anything else wrong with it. I tested the cannister control valve and nothing was wrong with it. Fuel tank filled up okay.

It means your engine is no longer needed to be fixed

i'm pretty sure that is your traction control system. look for a button labeled traction control, ets or something like that. then push it. Theres a rocker switch labeled "trac control" on the left of the steering column switch it one way to turn traction control on and the other way to turn it off, either way it wont harm anything. GM designed a glorious "Traction Control System", the purpose of which is unknown. What is known however, is that this system has broken on all Achievas known to be in existance. As you will notice if you follow the uninformed advice of the previous posters, activating the system causes any number of problems, many of which are dangerous. Naturally, rather than take any action to fix the problem, GM has tacitly advised dealers to merely turn the switch to off. (The fact that there even is a switch suggests that the system never worked, and indeed was never intended to.) Dealers typically then advice foolish consumers that the light "is meant to be off", which means they think Achieva drivers are among the dumbest people in America. I don't know what the "Traction Control System" is, but doesn't the light just mean you have turned the system ON and when light is off you have turned the system OFF? The traction control really only works in snow and ice. During the summer there is really no point in having it on. Without it your tires will spin. When activated it senses when the wheels starts spinning and cuts power for a second. It works the same as pumping the gas pedal. It works fine on my 96 and I wouldn't be able to get up my driveway without it. I would advise keeping the TCS off at all times, even during snow and ice. When I first started driving my 1996 Acheiva, I left the TCS on at all times. It took me about 6 months to burn out my rotors, repeatedly. I could not understand why they kept warping and getting destroyed. I have had it off for the past 3 years and I still have a good set of rotors. It is more trouble than it is worth. Drive slowly and sensibly in the rain and snow and you will be fine without it.

It depends the check engine light comes on usually when there is an issues with the computer that is related to misfiring, O2 sensor, etc. You can buy at an Auto parts store a code reader for $75 or you can pay yoru mechanic $75 to check the check engine light. I bought the code reader since once my check engine light came on it keep coming on for different reasons, but mainly for failure of coils and O2 sensors. If you live in a state where they require yearly emission checks then you can take it in and it will produce a failure which tells the fault. In my state that is $23.50, but you fix the issue and take back and they give you the inscpection sticker for no extra charge.. But the only way to find out why the light is one is to runt he computer and check the code.. good luck You can also get your codes read for free at Advanced Auto or Autozone. ANSWER I had this happen for quite some time, always had a diagnostic test come back clean. I was confused for some time, but found out that it was coming on because the gas cap wasn't tightened enough. Check to make sure it's on tight, or your check engine light will stay on if it isn't. This was an easy fix. I always check the minor things before thinking it's something major, because most of time it has been little things.

It should reset itself after you replace the cap, sometimes it may take a while. Pull the battery cable off and wait a few seconds before reconnecting. Or you can just unplug the 3 cables going into the ECM above the battery. You won't have to loosen any bolts that way. pull the negative battery cable for 10 min then reattach and should be out

what would make a 2000 ford windstar die out at stop lights and you have to put your foot on the brake and gas at the same time to keep it running and it sputters and jerks.

What you are looking for is the DLC or Data Link Connector which will require an OBD-II reader to retrieve codes from. The location of the DLC is on the driver's side under the dash.

First off repair the problem that set the light or it will just come back on. You can try disconnecting the negative battery cable for 5 minutes. If that does not work you will need to have it reset with a OBD2 scan tool.

Have the system checked for codes. That will lead you to the problem.

check the owners manual or the easiest way is to go to your local autozone and use their scanner tool to reset the light

IF it is the all the dash board lights it is probably a fuse, else if it only one light the switch on the is probably gone that lights up that light. There are no dash bulbs a they are LEDS so the chances of them blowing is slim

system failure

Trouble code P0441 means: Evaporative Emission System Incorrect Purge Flow

Most check engine lights can be reset if you know the pinout on the diagnostic plug by doing a simple jumping of terminals . To find out which terminals are involved consult a repair manual or if you have an Advance Auto Parts store nearby they can hook up the diagnostic computer and reset the check engine light. One other industry standard is to disconnect the battery , and then reconnect it . You may have to leave it disconnected for 20 minutes or so to reset the light, Again check a service manual- the library is a good place to find one without having to buy one(they are expensive) . Motors or Chiltons are usually pretty good quality and informative. The reset procedure is usually in there but may take a bit of searching to find . Hope this helps Use an OBD (On Board Diagnostic) scanner to find out what's wrong. Fix the problem then the light should go off. It's often an oxygen sensor or something equally trivial. By taking it to a professional and have the problem that the computer has detected repaired. pull the "Backup/ACC" fuse from the main panel under the hood. Wait 15-30 secs and replace it. However, this will reset all of your accessories as well and you will need to re-enter your security code on the radio to get it to work. 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. The " check engine light" is by far one of the most misunderstood technological advances by the public. I am sure I will revise this as time goes on, as it is an in-depth understanding for the public. It is a warning light that is illuminated when there is a problem with the EMISSION SYSTEM only. Emission system being the pollution control system. Don't get a hard on against it as it is a good thing once you understand it. One point that was brought up a a recent meeting of technicians was that the amount of hydrocarbons is greater when the gas cap is left off than when the engine is running. Hydrocarbons are part of pollution emitted as gasoline evaporates. Going a step farther, one facet of the emission system is the "Evaporative" portion. This is when the fumes from the gasoline are leaking from the system into the outside air. This is one part of the emission system that can trigger a check engine light. I would say that about 7% of the vehicles that have a check engine light are the result of a loose or inadequate gas cap. But understand that many scenarios are possible with the "check engine light" The vehicle's powertrain computer (note that some vehicles have 17 different computers) will run a series of self-tests. They will only run under certain criteria. And they can be vastly different from manufacturer to manufacturer. Some self-tests are not run until preceding ones have run successfully. So if there is a problem in one particular area that is preventing another self test from running, you can have a situation where one problem is fixed, but another still exists. If you fix a problem and drive the car through a drive cycle that sets the monitor (or self test) the light will go off as it passes that criteria that triggered it in the first place. After 1996, the auto industry went to a idea called OBD II (on board diagnostics). This was to get all the manufacturers onto a similar plane for troubleshooting and powertrain control. While they still differ vastly, many corrections and adaptations were made for technicians to better fix the check engine light problems. Prior to this there were so many different and poor troubleshooting data from a check engine light problem that resolving the problem was much more difficult. Many early warning light of this nature were set to illuminate based on mileage. An Oxygen sensor was one of the things that were meant to be replaced when that mileage was hit. This is much like many current "Change oil lights

Read the computer code by using the appropriate code scanner then you'll know for certain. The computer has stored a code to indicate what's wrong with the engine.

Check the speed sensor.

this means there is something going on with the engine. take it to a auto parts store and they will scan for the codes, for free. to tell you which curcuit its in. its a possibility that its a bad tps, or throttle cable, etc. God bless!
