Hi I have a 2002 Hyundai Elantra my check engine came on n got this code p0198 but I know for a fact that my power steering pump is leaking oil n I noticed that is dripping on top of my alternator is it possible that since is a electrical problem can that be the reason why the check engine came on ?...

The most likely cause of the P0198 code is the Engine Oil Temperature sensor,' If the power steering fluid is leaking over the sensor, then you should fix the leak first and then replace the sensor. Unfortunately I don't have a picture of the sensor location, but the sensor is on the lower left rear of the engine.
