Diagnostic Trouble Code (DTC) P1299 indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Failsafe Cooling was activated to cool the engine. (Refer to Section 1A, «Electronic Engine Control (EC) System», for more information on Failsafe Cooling Strategy and the cylinder head temperature sensor.)
Possible causes:
-- Engine cooling system concerns.
-- Base engine concerns.
-- Low engine coolant level or loss of coolant.
yes it can. if the check engine light shuts off by itself then chances are either the trouble code is a soft code. A hard code will keep the check engine light on until the problem is fixed and the check engine light is reset.
When the check engine light comes on it should post a code. Use a code reader to see what the code is and ask again.
and what code does the check engine light say ? go by autozone they will check it for free and get the code.
No, the check engine light comes on when the computer detects a malfunction and sets a code.No, the check engine light comes on when the computer detects a malfunction and sets a code.
Go to AutoZone and ask one of the fellas to come out and "check your check engine light code". They will be able to tell you what the problem code is, as well as re-set your check engine light.
Usual first sign is a check engine light with a code P0420.Usual first sign is a check engine light with a code P0420.
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.

Use an automotive computer code-scanner to read the stored code. Then you'll know why the "check engine" light is on.
The check engine light sets a code for diagnostics and you need a code reader. Most auto parts stores sell code readers and most will check the codes for free.
The check engine light comes on when the engine computer detects a malfunction and sets a trouble code.
When the check engine light is on, the computer sets a fault code. Most auto parts stores will check this code for free and tell you how to fix it.
