The P2248 fault code in automobiles indicates a problem with the Front Oxygen Sensor Bank 2.

The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty Front Oxygen Sensor Bank 2, an open or shorted harness, or a poor electrical connection in the circuit. The repair importance is high as it affects the vehicle’s emissions and fuel efficiency.

The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

It is essential to check the possible causes listed above to interpret the fault code correctly.

Repair Importance Level6.67 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2248 fault code.

Here are the symptoms to look out for:

  • The P2248 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include a decrease in engine power, poor acceleration, and reduced fuel efficiency.
  • The vehicle may also experience rough idling or stalling.
  • Additionally, the exhaust emissions may be higher than normal, and there may be a noticeable smell of fuel.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2248, including a faulty front oxygen sensor and poor electrical connection.

  • The automobile fault code P2248 can be caused by a faulty front oxygen sensor in bank 2.
  • It can also be caused by an open or shorted harness in the front oxygen sensor bank 2.
  • Additionally, a poor electrical connection in the front oxygen sensor bank 2 circuit can also trigger this fault code.

To fix the p2248 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code P2248, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2248 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P2248 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2248 code refers to the O2 Sensor Reference Voltage Performance of Bank 2 Sensor 1. This sensor is located in the exhaust manifold and detects the amount of oxygen in the exhaust gas compared to the outside air.

The heated oxygen sensor 1 generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The signal is sent to the Engine Control Module (ECM) which adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

What are the possible causes of the P2248 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2248 fault code. This code is caused by a faulty front oxygen sensor in bank 2, an open or shorted harness, or a poor electrical connection in the front oxygen sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2248 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2248 fault code, you may need to visually inspect the related wiring harness and connectors. This is because the cause of the issue could be a faulty Front Oxygen Sensor Bank 2, an open or shorted harness, or a poor electrical connection in the circuit. To fix the problem, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P2248 fault code and not fixing it?

Ignoring the P2248 fault code, caused by a faulty front oxygen sensor bank 2 or related wiring issues, can lead to decreased fuel efficiency, engine damage, and increased emissions. The engine light will remain on, indicating a problem, and the vehicle may fail emissions tests. It is important to visually inspect the wiring harness and connectors and check for damaged components to fix the issue.
