The P2245 fault code in automobiles indicates a problem with the front oxygen sensor bank 1.

The most common symptom is the engine light turning on.

The cause of this issue could be a faulty front oxygen sensor bank 1, an open or shorted harness, or a poor electrical connection in the circuit.

It is important to address this issue promptly as it can lead to decreased fuel efficiency and increased emissions. The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion. The difficulty level of this repair is moderate, and it can take up to 1.0 hour to fix.

To interpret the fault code, one should check the possible causes listed above and visually inspect the related components.

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 p2245 fault code.

Here are the symptoms to look out for:

  • The P2245 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, poor fuel economy, rough idling, and difficulty starting the engine.
  • Additionally, the vehicle may experience stalling or misfiring, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2245 can be caused by a faulty front oxygen sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2245 can be caused by a faulty front oxygen sensor in bank 1.
  • It can also be caused by an open or shorted harness in the front oxygen sensor bank 1.
  • Additionally, a poor electrical connection in the front oxygen sensor bank 1 circuit can also trigger this fault code.

To fix the p2245 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2245, first, check the possible causes listed above.
  • Then, 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 P2245 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the P2245 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2245 code refers to the O2 Sensor Reference Voltage Circuit Low Bank 1 Sensor 1. The Front Oxygen Sensor (O2 Sensor 1) is located in the exhaust manifold.

It 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 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 P2245 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2245 fault code. This code is caused by a faulty front oxygen sensor in Bank 1, an open or shorted harness, or a poor electrical connection in the 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’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P2245 fault code?

If you’re experiencing the P2245 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Front Oxygen Sensor Bank 1, an open or shorted Front Oxygen Sensor Bank 1 harness, or a poor electrical connection in the Front Oxygen Sensor Bank 1 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.

What are the consequences of ignoring the P2245 fault code and not fixing it in a timely manner?

Ignoring the P2245 fault code, which indicates a faulty front oxygen sensor 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 to avoid further damage and costly repairs.
