last night the "check engine" light came on

QUESTION:
I have a 1998 Honda Civic EX and just recently had a yearly maintenance in July 2008. Just last night the "check engine" light came on. What can be the problem with my Honda? What signs can I look for? Where do I start for troubleshooting since I don't have the manual?
ANSWER:
An error has been detected by the engine management system and you need a computer scan done to find out what is causing the check engine light illuminate. You can get it done for free at your local Autozone or you can purchase a scan tool and do it yourself.

How to check trouble codes on a 92 la sabre without the scanner

Checker and autozone type places will pull the codes for you for free most the time. Because they will sell you the part to fix it right there too. If you want to do it yourself, no problem. Follow these steps : EXTRACT GM TROUBLE CODES You will find step by step procedures for extracting the codes yourself along with code descriptions and causes for each code. EXAMPLE: CODE 24 Trouble Code 24 indicates that the Vehicle Speed Sensor (VSS) is reporting an abnormally low reading when other sensors indicate it should be higher. The conditions for setting this code are: 1) no Code 33 or 34 (MAF Error) is present, and 2) the vehicle speed signal indicates < 4 MPH and 3) engine speed is between 1400 and 4400 RPM, and 4) during a low load condition (LV8 between 50 and 99), and 5) transmission not in Park or Neutral, and 6) all conditions met for more than 20 seconds If the code was logged when the vehicle was in motion, the following should be checked: 1) Defective or corroded VSS connections 2) Maladjusted TPS sensor. The TPS should read about 0.42 volts at closed throttle 3) Defective speedometer cable 4) Bad or missing speedo drive gear(s) in tail shaft housing of the transmission 5) Defective VSS 6) Defective ECM

How do I extract the check engine light codes?

QUESTION:
I have a 1995 Ford Mustang GT and my check engine light is on. How do I extract the codes? Do I need a scan tool or can I do it without one?
ANSWER:
You do not need a scan tool to extract the codes on this vehicle. This vehicle is OBD I and does not switch till 1996 so you do not need a scan tool. Basically you install a jumper wire or paper clip in the diagnostic test port located under the hood toward the passenger side firewall. Once the jumper is in place, you turn the key on (do not start engine) and the check engine light will flash the code. Here is a link to Complete Instructions and a full list of Ford OBD I Check Engine Light Codes with descriptions of each code: EXTRACT FORD CODES
