    If you have to spend more than $30 consider getting yourself a code scanner they can be had for around $40 for a basic model

    This one has OBDII and CAN for the newer vehicles

    harbor freight has a clone also around $40

    This is the one I got since it not only shows the code it tells you what it means without having to look it up, its all there on the screen

    What you say about clearing codes is very true. There's a good reason why. When a code sets the computer goes into failsafe to protect the engine or transmission. Example: The transmission is slipping because it has a slow leak that went unnoticed until the fluid got too low. Back in the old days you would continue to drive your car until you burned up the clutches. Now the computer turns on the light, jacks up the line pressure, and disables shifting. This forces you to take your car in to get it fixed. Just clearing the code can cause more damage.

    The same holds true for an engine code. Example: Your engine is pinging because of lean condition. The computer sees this and retards the timing. Your check engine light comes on and your truck runs like crap. This forces you to take it in and have it fixed. Clearing the code can just cause more damage.

    As far as code readers go if you are going to buy one, spend the extra money and get one that has DATA. Without any data all you can do is read and clear codes. You canít see what the suspect sensor is doing and without the DATA you just canít find and fix the problem.

    take a jumper wire and jump it with the key off from the test terminal to the ground terminal the two upper right plug holes then turn the key on do not start it!!!!! Then the service engine soon light will flash code 12 it will be one flash a short pause then two flashes after another slightly longer pause the code will repeat itself two more times that says the diagnostic syatem is working if there is nothng wrong 12 will repeat itself over and over but if there is a problem it will flash the code 3 times then code 12 3 times and the next code if there is more than 1 code stored
