Light came on last week and will not shut off. I tightened the gas cap the first day and it hasn't went away. I have tried to get the codes read from an auto parts store, but there are no codes.

I have also tried to do the manual read, but once I turn the car to the on position several lights stay on instead of just the service light. I have looked everywhere and can't find an answer.

Am I looking in the wrong places? Should I take it to a dealership?

I don't know to be honest. Just whatever they use at the autozone type store. Went to two different places and the keyless ignition seemed to throw them for a loop. I just kept my foot off the brake and hit the button twice to turn the car "on". They plug in and get no codes. Am I doing that wrong?

To take a reading without using an OBD II reader, you can do this...

1. Put the car into "on" without the engine started (aka, hit the ignition button twice without having your foot on the brake)

2. Wait 3 seconds for the car to do a systems check (you know this is done when all the lights except your service engine light go off)

3. Do 5 full accelerator press and releases in 5 seconds (floor your car 5 times in 5 seconds)

4. Wait 7 seconds.

5. Floor the accelerator again, and hold it there for 10 seconds (approx). Your service engine light will turn off.

6. When the light turns off, take your foot off the pedal, and get ready to count.

At this point, the service engine light will start blinking. It will give you a 4 digit code - the first number will flash slowly, followed by a slight pause, the next three numbers will flash quickly, all with a pause in the middle. 10 flashes means a number "0." So if your car blinked 10 times, then 4, then 4, then 2 (edited from 4) again, you would have a code of "0442," which is your gas cap thing. Other codes can be determined by looking at a OBD II code reference sheet, which can be found by googleing it, or probably somewhere in the forums...

I have tried that several times. During step 2 several lights stay on, instead of everything turning off except the service engine light. I will probably disconnect the battery tomorrow to do a hard reset, but I doubt that will help.

I wouldn't disconnect the battery until you know what they code is for. If the ecu hasn't turned the light off, that means it has not seen the right parameters to turn it off, which means the problem is still present. Take it to a REPUTABLE place that knows what they are doing. Unfortunatley, I don't consider an auto parts store a place that knows what they are doing when it comes to scanning a vehicle.

My service engine soon light came on and i took it to auto zone for a code check. Came back that its a fault in the output shaft speed sensor. Is this a major problem that i should attend to immediately or will i be fine driving my car around for a couple more weeks until i can get enough money to pay a mechanic to fix it?
