Code P0198 Hyundai Description
The P0198 OBD-II trouble code refers to the high input of the engine oil temperature sensor in a Hyundai vehicle. The engine oil temperature sensor is responsible for monitoring the temperature of the engine oil, which is crucial for proper engine operation and performance. When this sensor detects a high input, it means that the engine oil temperature is higher than normal, potentially indicating an issue with the engine's cooling system or oil circulation. This can lead to inefficient engine operation, reduced fuel efficiency, and potential engine damage if not addressed promptly.
Common Causes of P0198 Hyundai
- Faulty engine oil temperature sensor
- Wiring or connector issues in the sensor circuit
- Engine coolant temperature sensor malfunction
- Engine cooling system problems, such as a faulty thermostat or radiator
- Engine oil circulation issues, such as low oil level or poor oil quality
Symptoms of P0198 Hyundai
- Illuminated check engine light on the dashboard
- Engine overheating or running hotter than usual
- Reduced fuel efficiency
- Engine misfires or rough idling
- Engine performance issues such as loss of power or acceleration
How to Fix P0198 Hyundai
- Use an OBD-II scanner to confirm the P0198 trouble code and diagnose the specific cause of the high input.
- Inspect the engine oil temperature sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Check the engine coolant temperature sensor and engine cooling system components for any faults. Repair or replace as needed.
- Verify proper engine oil level and quality. Top up or change the oil if required.
- Clear the trouble code from the vehicle's ECU and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0198 Hyundai

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.
