The check engine light comes on when the engine computer has detected a malfunction and set a trouble code.
If the check engine light is flashing that means an engine cylinder misfire has been detected
Take it to advance auto and they will do it for free.
You use a scan tool after repairing the cause of the code that turned the light on.
A check engine light informs you that there is something wrong with the engine. After you run a diagnostic test, you will be able to tell what exactly is wrong.
Im guessing there is something wrong with your car!
If your check engine light is staying on , that indicates that a malfunction has been detected with the emission control system . You need to have your Explorer scanned for any trouble codes in order to diagnose and repair the problem , then the light can be reset
The light that shows an engine symbol is your check engine light . If the light stays on while the engine is running, the OBD II system has detected a possible problem with your emission system. If the light flashes on and off, an engine "miss" has been detected . Have your Explorer scanned for any trouble codes to find and then repair the problem.
sometimes after making a repair or replacement, the computer needs to be reset by a mechanic
It has a " check gage " light if the fuel gauge is at or near empty , the engine coolant temperature is high , or the engine oil pressure is low
In a 2002 Ford Explorer Sport Trac : The CHECK " GAGE " warning light comes on if the the oil pressure is too low , the engine cooling temperature is too high , or the gas tank gauge is near or at empty
It allows the OBD II scanner to connect to your Ford Explorer to " read " any trouble codes when the check engine light comes on for one thing
I assume it is the same as the 1998 Ford Explorer four door : There is a " CHECK GAGE " light ( just to the left and above the tachometer ) The light comes on if the engine coolant temperature is too HIGH , the engine oil pressure is too LOW , or the gas gauge is at or near empty
