  • The automobile fault code P2224 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.

To fix the automobile fault code p2224, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2224, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 P2224 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 P2224 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2224 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 P2224 code specifically refers to the NOx Sensor Heater Sense Circuit High Bank.

What are the possible causes of the P2224 automobile fault code?

If you’re experiencing the P2224 fault code, your engine light may be on. This could be due to 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 the issue, check the possible causes listed above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded connector pins.
