If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2223 fault code.

Here are the symptoms to look out for:

  • The P2223 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 acceleration, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience issues with the transmission, such as difficulty shifting gears or slipping.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2223 fault code can be caused by a faulty NOx sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2223 can be caused by a faulty Nitrogen Oxide (NOx) sensor.
  • It can also be caused by an open or shorted Nitrogen Oxide (NOx) sensor harness.
  • Additionally, a poor electrical connection in the Nitrogen Oxide (NOx) sensor circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2223, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code P2223, 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 P2223 indicates a problem with the Barometric Pressure Circuit High Input.

The diagnosis cost may vary depending on the auto repair shop, but it is common to charge between $75 and $150 per hour.

The estimated repair time for this fault code is 1.0 hour. The fixing cost will depend on the severity of the problem and the parts that need to be replaced.

It is important to address this issue promptly to avoid further damage to the vehicle.

The P2223 code is related to the Nitrogen Oxide (NOx) sensor in the exhaust system of a vehicle.

This sensor measures the amount of nitric oxide and nitrogen oxide in the exhaust system.

When the NOx sensor indicates that the storage capacity has been reached, the regeneration phase is initiated by the fueling management system.

The Powertrain Control Module (PCM) monitors the NOx sensor and sets the code when the NOx sensor circuit voltage reading is not within the normal operating threshold for a specific engine bank. The P2223 code specifically refers to the NOx Sensor Heater Sense Circuit Low Bank.

What are the possible causes of the P2223 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2223 fault code. This code is caused by a faulty Nitrogen Oxide (NOx) Sensor, an open or shorted NOx Sensor harness, or a poor electrical connection in the NOx 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’s pins.
