If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2242 fault code. Here are the symptoms to look out for:

  • The P2242 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 misfires, stalling, or difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2242 fault code can be caused by a faulty front heated oxygen sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2242 can be caused by a faulty front heated oxygen sensor bank 2.
  • It can also be caused by an open or shorted front heated oxygen sensor bank 2 harness.
  • Additionally, a poor electrical connection in the front heated oxygen sensor bank 2 circuit can also trigger this fault code.

To fix the p2242 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage.

  • To fix the automobile fault code p2242, 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 fault code P2242 indicates an issue with the oxygen sensor circuit in bank 2 sensor 1.

The diagnosis process involves checking the wiring and connections, as well as testing the sensor itself. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this fault code can vary depending on the hourly rate of the auto repair shop, which is typically between $75 and $150 per hour. Other factors that may affect the cost include the cost of the replacement parts and any additional repairs that may be required.

The P2242 code refers to the O2 Sensor Positive Current Control Circuit High 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 P2242 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2242 fault code. This code is caused by a faulty Front Heated Oxygen Sensor Bank 2, 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 I visually inspect the wiring harness and connectors related to the Front Heated Oxygen Sensor Bank 2?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Front Heated 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 Heated Oxygen Sensor Bank 2 harness is open or shorted, or if there is a poor electrical connection in the circuit.

What are the consequences of not fixing the P2242 fault code?

Ignoring the P2242 fault code, which indicates a faulty front heated oxygen sensor bank 2, can lead to serious consequences such as reduced fuel efficiency, engine damage, and increased emissions. It is important to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins to fix the issue.
