Question about 2000 Hyundai Elantra
When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this code, you may begin diagnosis.
Since the 'Check Engine' light flashed, and there were no codes stored (at least this is what the technician told you), there is definitely something happening with the engine computer. There is ALWAYS a code stored when the Check Engine light comes on - even if it's a 'History' code (unless there's a problem with the computer).
Have a qualified/certified Hyundai Service Technician properly diagnose this issue.
