Code P2245 Hyundai Description
The O2 Sensor Reference Voltage Circuit Low Bank 1 Sensor 1 diagnostic trouble code (DTC) P2245 in a Hyundai indicates that there is an issue with the oxygen sensor's reference voltage circuit for the first sensor in Bank 1. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency. When the reference voltage circuit is reading lower than the specified parameters, it can lead to performance issues in the vehicle.
Common Causes of P2245 Hyundai
- Faulty oxygen sensor
- Wiring harness issues
- ECM malfunction
- Power supply problems
- Poor electrical connections
Symptoms of P2245 Hyundai
- Decreased fuel efficiency
- Rough idling or engine hesitation
- Engine misfires
- Stalling or difficulty starting the vehicle
- Check Engine Light illuminated on the dashboard
How to Fix P2245 Hyundai
- Use a diagnostic scanner to retrieve the specific trouble code and verify the issue.
- Inspect the wiring harness and oxygen sensor connections for any damage or corrosion.
- Test the oxygen sensor's reference voltage circuit to determine if it is within specifications.
- Replace the oxygen sensor if it is found to be faulty or not providing the correct voltage.
- Clear the trouble code from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2245 Hyundai
The typical repair costs for addressing the P2245 code in a Hyundai can vary depending on the specific cause of the issue and the cost of parts and labor. On average, the cost of replacing an oxygen sensor can range from $200 to $400, including both the part and labor. However, additional diagnostic time and potential repairs may increase the total cost. It's recommended to consult with a professional mechanic or auto repair shop for a more accurate estimate based on the vehicle's make and model. Keep in mind that labor rates can vary based on location and the type of repair facility.

Frequently Asked Questions about P2245 Hyundai Code
1. What does the OBDII code P2245 mean for a Hyundai?
P2245 indicates that the oxygen (O2) sensor reference voltage circuit for Bank 1 Sensor 1 is reading abnormally low, which may affect engine performance and emissions.
2. What are the symptoms of the P2245 code in a Hyundai?
Common symptoms include poor fuel efficiency, rough idling, engine hesitation, an illuminated check engine light, and potential engine misfires.
3. What causes the P2245 code to appear on a Hyundai?
Typical causes include a faulty O2 sensor, damaged wiring or connectors in the reference voltage circuit, a malfunctioning ECM, or corrosion in the sensor connections.
4. Which O2 sensor is affected by the P2245 code?
The code refers to Bank 1 Sensor 1, which is the upstream (pre-catalytic converter) oxygen sensor on the side of the engine with cylinder 1.
5. Can I keep driving my Hyundai with a P2245 code?
Driving with this code is not recommended, as it can lead to poor fuel economy, increased emissions, and potential damage to the catalytic converter over time.
6. How can I diagnose the P2245 code on my Hyundai?
Start by inspecting the wiring and connectors for damage or corrosion. Then, use a multimeter to test the sensor reference voltage and compare it to the manufacturer’s specifications.
7. How do I fix the P2245 code on a Hyundai?
Repairs may include replacing the faulty O2 sensor, repairing or replacing damaged wiring, cleaning corroded connections, or reprogramming or replacing the ECM if necessary.
8. How much does it cost to repair a P2245 code on a Hyundai?
The cost can range from $150 to $400 or more, depending on whether the O2 sensor, wiring, or ECM needs repair or replacement.
9. Can a dirty air filter cause a P2245 code on a Hyundai?
No, a dirty air filter is unlikely to cause this specific code, as it is related to the O2 sensor’s reference voltage circuit rather than airflow.
10. Will clearing the P2245 code fix the problem?
Clearing the code may turn off the check engine light temporarily, but if the underlying issue isn’t addressed, the code will likely return.
