The P2239 automobile fault code indicates a problem with the Front Heated Oxygen Sensor Bank 1. This can cause the Engine Light to turn on, indicating a need for service.

The cause of this issue could be a faulty sensor, an open or shorted harness, or a poor electrical connection. It is important to visually inspect the wiring harness and connectors for any damage or corrosion.

The repair time for this issue is estimated to be around 1.0.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and follow the suggested fix.

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 p2239 fault code.

Here are the symptoms to look out for:

  • The P2239 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 fuel efficiency, rough idling, engine misfires, and difficulty starting the vehicle.
  • Additionally, the car may experience a lack of power or acceleration, and the exhaust emissions may be higher than normal.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2239 can be caused by a faulty oxygen sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2239 can be caused by a faulty front heated oxygen sensor bank 1.
  • It can also be caused by an open or shorted front heated oxygen sensor bank 1 harness.
  • Additionally, a poor electrical connection in the front heated oxygen sensor bank 1 circuit can also trigger this fault code.

To fix the p2239 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2239, 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 P2239 is related to the oxygen sensor circuit on Bank 1 Sensor 1. The diagnosis cost may vary depending on the auto repair shop, but it is usually included in the repair cost.

The estimated repair time for this fault code is 1.0 hour, which is a significant factor in determining the fixing cost. Most auto repair shops charge between $75 and $150 per hour, which means the fixing cost for P2239 can range from $75 to $150. Other factors that may influence the fixing cost include the type of vehicle, the location of the auto repair shop, and the severity of the issue.

The P2239 code refers to the O2 Sensor Positive Current Control Circuit High Bank 1 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 P2239 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2239 fault code. This code is usually caused by a faulty Front Heated Oxygen Sensor Bank 1, an open or shorted Front Heated Oxygen Sensor Bank 1 harness, or a poor electrical connection in the Front Heated 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.

How can I visually inspect the wiring harness and connectors related to the Front Heated Oxygen Sensor Bank 1?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Front Heated Oxygen Sensor Bank 1, 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 Heated Oxygen Sensor Bank 1 harness is open or shorted, or if there is a poor electrical connection in the circuit.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection, it is important to visually inspect the related wiring harness and connectors. This could be the cause of the Engine Light ON (or Service Engine Soon Warning Light) and the faulty Front Heated Oxygen Sensor Bank 1. Check for any possible causes listed above and ensure that the Front Heated Oxygen Sensor Bank 1 harness is not open or shorted and that the circuit has a good electrical connection.
