Solid SERVICE ENGINE SOON light
This means that the On Board Diagnostic System (OBD II) has detected a malfunction. Temporary malfunctions may cause your SERVICE ENGINE SOON light to illuminate. Examples are:
- The vehicle has run out of fuel. (The engine may misfire or run poorly.)
- Poor fuel quality or water in the fuel.
- The fuel cap may not have been properly installed and securely tightened.
The temporary malfunctions can be corrected by filling the fuel tank with good quality fuel and/or properly installing and securely tightening the gas cap. After three driving cycles with out these or any other temporary malfunctions present, the SERVICE ENGINE SOON light should turn off. (A driving cycle consists of a cold engine start-up followed by mixed city/highway driving.) No additional vehicle service is required.
Blinking SERVICE ENGINE SOON light
Engine misfire is occurring which could cause damage to your catalytic converter. You should drive in a moderate fashion (avoid heavy acceleration and deceleration) and have your vehicle serviced at the first available opportunity.
