[SOLVED] P220E Code: Fixing Nox Sensor Heater Control Circuit Range/Performance

The P220E automobile fault code indicates a problem with the NOx sensor or its circuitry. This can cause the engine light to turn on, indicating a potential issue with the vehicle. The cause of this fault code could be a faulty NOx sensor, an open or shorted NOx sensor harness, a poor electrical connection in the NOx sensor circuit, or a faulty Engine Control Module (ECM).

It is important to visually inspect the wiring harness and connectors for any damage or corrosion. The repair time for this fault code is estimated to be around 1.0 hour. To interpret the fault code, it is recommended to check the “Possible Causes” listed above and inspect the related components.

If you notice the engine light on or service engine soon warning light, it could be a sign of p220e fault code. Here are the symptoms to look out for:

  • The P220E fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting issues, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P220E can be caused by a faulty NOx sensor, open or shorted NOx sensor harness, poor electrical connection in the NOx sensor circuit, or a faulty Engine Control Module (ECM).

  • The automobile fault code P220E can be caused by a faulty NOx sensor.
  • It can also be caused by an open or shorted NOx sensor harness.
  • Poor electrical connection in the NOx sensor circuit can also trigger this fault code.
  • Lastly, a faulty Engine Control Module (ECM) can also be a cause of the P220E fault code.

To fix the p220e automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code P220E, first, check the possible causes listed above.
  • Then, 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 P220E can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosing and fixing the P220E fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P220E fault code is stored when there is a malfunction in the NOx sensor circuit. This code is commonly found in lean burn and direct injection vehicles that use a Selective Catalytic Reduction system (SCR). The NOx sensor detects when a regeneration is required and when it is complete.

A heater circuit is needed to quickly get the NOx sensor up to operating temperature for reliable performance. The NOx sensor has a module located near it that communicates with the engine control module.

The P220E code specifically refers to the NOx Sensor Heater Control Circuit RangePerformance Bank 1 Sensor 1.

What are the possible causes of the automobile fault code P220E?

If you see the engine light on or service engine soon warning light, it could be due to the P220E fault code. This code is usually caused by a faulty NOx sensor, an open or shorted NOx sensor harness, poor electrical connection in the NOx sensor circuit, or a faulty Engine Control Module (ECM). 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 related wiring harness and connectors to fix the P220E fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P220E fault code, there are a few possible causes to consider. One of them is a faulty NOx Sensor, which can be fixed by visually inspecting the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the NOx Sensor harness is open or shorted, or if there’s a poor electrical connection in the NOx Sensor circuit. Additionally, check for a faulty Engine Control Module (ECM).

Is a faulty NOx sensor the only cause of the P220E fault code, or are there other potential causes that should be checked?

While a faulty NOx sensor is a common cause of the P220E fault code, there are other potential causes that should be checked. These include an open or shorted NOx sensor harness, poor electrical connection in the NOx sensor circuit, and a faulty Engine Control Module (ECM). To fix the issue, 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.
