Code P220E Dodge Description

This fault code is stored when a malfunction is detected with the NOx sensor circuit. Some lean burn and direct injection vehicles will use a Selective Catalytic Reduction system (SCR), which uses a NOx accumulator to store oxides of Nitrogen and allows them to be reduced at a suitable time. A NOx sensor is used to detect when a regeneration is required and when the regeneration is complete. The NOx sensor will have a module located close to the sensor which communicates with the engine control module. A heater circuit is required to get the NOx sensor up to operating temperature quickly to allow for reliable performance in a timely manner.

2. What are the common symptoms of the P220E code?

Symptoms may include an illuminated check engine light, reduced fuel efficiency, poor engine performance, and possibly entering limp mode.

3. What causes the P220E code to trigger?

Common causes include a faulty NOx sensor, damaged wiring or connectors, a malfunctioning sensor heater, or an issue with the engine control module (ECM).

4. How does the NOx sensor heater affect the engine?

The heater warms the NOx sensor to ensure accurate readings. If it malfunctions, the sensor may not work correctly, leading to improper emissions control.

5. Can I drive with the P220E code on my Dodge?

While it may be possible to drive, it is not recommended. Ignoring the issue could lead to increased emissions, reduced performance, and potential damage to other components.

6. How do you diagnose the P220E code?

Diagnosis typically involves scanning for codes, inspecting the NOx sensor and its wiring, testing the sensor heater circuit, and checking ECM outputs.

7. What is the most common fix for the P220E code?

Replacing the faulty NOx sensor is the most common fix, though repairing damaged wiring or updating the ECM software may also resolve the issue.

8. How much does it cost to fix the P220E code?

Repair costs can vary but typically range between $300 and $800, depending on whether the NOx sensor or other components need replacement.

9. Can a software update resolve the P220E code?

In some cases, a software update for the ECM may fix the issue if it is related to incorrect programming.

10. How can I prevent the P220E code from recurring?

Regular maintenance, keeping wiring and connectors in good condition, and using high-quality fuel can help prevent NOx sensor-related issues.
