The P2247 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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2247 fault code.

Here are the symptoms to look out for:

  • The P2247 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, reduced fuel efficiency, and rough idling.
  • Additionally, the vehicle may experience stalling or difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

There are several causes of the automobile fault code p2247, including a faulty front oxygen sensor and poor electrical connection.

  • The automobile fault code P2247 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.

Below are the possible fixes for the automobile fault code: p2247, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2247, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 fault code P2247 indicates an issue with the oxygen sensor circuit in bank 2 sensor 1. The diagnosis cost may vary depending on the auto repair shop, but it is usually charged per hour.

The estimated repair time for this fault code is 1.0 hour. The fixing cost may range between $75 and $150 per hour, depending on the auto repair shop. These factors can influence the overall cost of diagnosing and fixing the P2247 fault code.

The P2247 code indicates a problem with the reference voltage circuit of the O2 sensor in bank 2, sensor 1.

This sensor is located in the exhaust manifold and measures 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 from this sensor is sent to the Engine Control Module (ECM), which adjusts the injection pulse duration to achieve the ideal air-fuel ratio. If the reference voltage circuit of the O2 sensor in bank 2, sensor 1 is open, the ECM will not receive a signal from the sensor.

This can cause issues with the air-fuel ratio and may result in decreased engine performance and increased emissions.

What are the possible causes of the P2247 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2247 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 one visually inspect the related wiring harness and connectors to fix the P2247 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2247 fault code, you may need to visually inspect the related wiring harness and connectors. This fault code is often caused by a faulty Front Oxygen Sensor Bank 2, an open or shorted harness, or a poor electrical connection. To fix the issue, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Be sure to check the “Possible Causes” listed above before proceeding with any repairs.

What are the consequences of ignoring the P2247 fault code and not fixing it in a timely manner?

Ignoring the P2247 fault code, which indicates a faulty front oxygen sensor bank 2 or related wiring issues, can lead to decreased fuel efficiency, engine performance issues, and potential damage to the catalytic converter. It is important to address the issue promptly by visually inspecting the wiring harness and connectors and checking for damaged components.
