Ford Repair: codes, ford bronco, o2 sensor


Question
Hi I was wondering about my check engine light in my 96 Ford Bronco 5.8L  I had the code read and found out it was my O2 sensor so I changed both of them. The check engine light is still on. Do I have to clear it with the diagnostic tool?

Answer
Just having a code does not necessarily mean the sensor was bad. If you could have told me the code I could be more help.

Codes are a starting point, there are very few that anyone can actually say is a specific part without further tests. Many problems can set a code that might indicate a sensor, doesn't mean the sensor is the problem.

You can turn the CEL off and clear the code by disconnecting the battery for a few minutes. This clears the computer memory of certain learned parameters and all codes. Without a scanner this is the easiest way to accomplish code clearing. Keep in mind that if the sensor was not the problem to begin with, the code will return.
