Code P2248 KIA Description

The P2248 diagnostic trouble code (DTC) for KIA vehicles specifically refers to the O2 Sensor Reference Voltage Performance for Bank 2 Sensor 1. This code indicates that there is a problem with the reference voltage being supplied to the O2 sensor located in bank 2, sensor 1 of the vehicle. The O2 sensor plays a crucial role in 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.

2. What are the common symptoms of P2248 in a KIA?

Symptoms may include a check engine light, poor fuel economy, rough idling, reduced engine performance, and increased emissions.

3. What causes the P2248 code in a KIA?

Common causes include a faulty oxygen sensor, damaged wiring or connectors, a malfunctioning powertrain control module (PCM), or an exhaust leak upstream of the sensor.

4. Which sensor is affected by the P2248 code?

The code refers to Bank 2 Sensor 1, which is the upstream oxygen sensor on the side of the engine opposite Cylinder 1.

5. How is the P2248 code diagnosed?

A technician will check the O2 sensor’s voltage readings using a scan tool, inspect the wiring and connectors, and test for any exhaust leaks or PCM issues.

6. Can I drive my KIA with the P2248 code active?

While the vehicle may still be drivable, it is not recommended as it can lead to poor engine performance, increased emissions, and potential damage to other components.

7. How do I fix the P2248 code in my KIA?

Repairs may involve replacing the faulty oxygen sensor, fixing damaged wiring or connectors, addressing an exhaust leak, or reprogramming or replacing the PCM.

8. How much does it cost to fix the P2248 code on a KIA?

Costs vary but typically range from $150 to $400 for oxygen sensor replacement, with additional costs if wiring or PCM repairs are needed.

9. Can a dirty air filter cause the P2248 code?

A dirty air filter is not a direct cause of P2248 but can contribute to engine performance issues that may affect oxygen sensor readings.
