The P2249 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 p2249 fault code.

Here are the symptoms to look out for:

  • The P2249 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, poor acceleration, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

There are several causes of the automobile fault code p2249, including a faulty front oxygen sensor and poor electrical connection.

  • The automobile fault code P2249 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 p2249 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2249, 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 automobile fault code P2249 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 P2249 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 P2249 code refers to the O2 Sensor Reference Voltage Circuit Low 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 P2249 automobile fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2249 fault code. This code is caused by a faulty Front Oxygen Sensor Bank 2, an open or shorted Front Oxygen Sensor Bank 2 harness, or a poor electrical connection in the Front Oxygen Sensor Bank 2 circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Front Oxygen Sensor Bank 2?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Front Oxygen Sensor Bank 2, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Front Oxygen Sensor Bank 2 harness is open or shorted, or if there is a poor electrical connection in the Front Oxygen Sensor Bank 2 circuit.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors, follow these steps. First, check the “Possible Causes” listed above. Then, visually inspect the related wiring harness and connectors. Finally, look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins. This will help you fix the issue of the Engine Light ON (or Service Engine Soon Warning Light) caused by a faulty Front Oxygen Sensor Bank 2, Front Oxygen Sensor Bank 2 harness being open or shorted, or Front Oxygen Sensor Bank 2 circuit poor electrical connection.
