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.
