I am not sure of the other 4 reasons But in my experience the top reason your check engine light comes on is because your gas cap isn't tightened all the way.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

There is an engine misfire, probably spark plugs issue.

There should be a dipstick like the one for oil. Check with engine running.

The light could come on for a number of reasons. The vehivle would have to be hooked up to a scanner to determine the engine code or codes. After you determine the codes you can isolate and fix the probelem. If the check engine light is on there will be a computer code that will appear on the scanner.

There are no top reasons. A simple scan of the ECU with an OBD2 scan tool will retrieve the code and tell you what part is being effected. Most auto parts stores will do this for free.

To reset the check engine light unplug the battery for 30 minutes. If the issues still persists the light will still light up when reattached.

If the check engine light is illuminated, start with scanning for codes.

Look on the side of the coolant overflow bottle. There should be a low mark for the coolant for a cool engine, and one for a hot engine.

The code P1887 is for torque converter clutch release switch malfunction.
