You will have to go get a scan done to read the set fault code, post the code here for further assistance.

Check for self check codes 1st
Without starting engine, turn ignition on, off, on, off and on within 5 seconds. Record 2-digit Diagnostic Trouble Codes (DTCs) as displayed by flashing MIL.
For example, DTC 41 will be displayed by 4 flashes, short pause, and then one flash. A short pause will exist between first and second digits on DTC. If more than one DTC is stored, after first DTC is displayed, there will be a longer pause and then another stored DTC will be displayed.
