[SOLVED] P2212 Code: Fixing Intermittent Nox Sensor Heater Circuit – Bank 1

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2212 fault code. This code indicates a problem with the Nitrogen Oxide (NOx) Sensor, which could be faulty or have a poor electrical connection. The possible causes include an open or shorted NOx Sensor harness.

The repair importance of this issue is high as it can affect the vehicle’s emissions and performance. The repair difficulty is moderate, and it may take around 1.0 hour to fix. To interpret the fault code, you need to check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the engine light on or service engine soon warning light, it could be a sign of p2212 fault code. Here are the symptoms to look out for:

  • The P2212 fault code in an automobile can cause several symptoms.
  • These include the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, poor acceleration, and rough idling.
  • The vehicle may also experience stalling or difficulty starting.
  • Additionally, the fuel efficiency may decrease, and there may be an increase in emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2212 fault code can be caused by a faulty NOx sensor, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2212 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 p2212 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p2212, 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 fault code P2212 indicates a problem with the intake air control system. The diagnosis and fixing cost of this fault code is influenced by several factors, including the estimated repair time, which is typically 1.0 hour. The cost of repair is also affected by the hourly rate charged by the auto repair shop, which can range from $75 to $150 per hour.

Other factors that may impact the cost include the severity of the issue, the type of vehicle, and the availability of replacement parts.

The P2212 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 P2212 code specifically refers to the NOx Sensor Heater Sense Circuit Intermittent Bank.

What are the possible causes of the P2212 automobile fault code?

If you’re experiencing the P2212 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 this issue, check the possible causes listed above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the P2212 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2212 fault code, it could be 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 related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Don’t forget to check the “Possible Causes” listed above.

What are the specific steps I can take to check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins to fix the P2212 fault code?

If you’re experiencing the P2212 fault code, start by checking the possible causes: 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, visually inspect the related wiring harness and connectors, and check for damaged components. Look for broken, bent, pushed out, or corroded connector’s pins to ensure everything is in working order.
