their is more than one oxygen sensor but the one that is probly bad is on the exhaust system. otherwise I would check the map sensor.

Check engine light comes on, mileage drops, may end up toasting a cylinder coil which is a cylinder misfire or flashing check engine light.

Code P1299: Cylinder Head Over Temperature Protection Active Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Fail-safe Cooling was activated to cool the engine. Engine cooling system concerns Low engine coolant level Base engine concerns

If the check engine light is blinking , that indicates a cylinder misfire has been detected White smoke coming out of the exhaust ( especially when the engine is warmed up ) indicates that coolant is getting into an engine cylinder from a bad head gasket , a warped or cracked cylinder head
