P220E Dodge Code - NOx Sensor Heater Control Circuit Range/Performance Bank 1 Sensor 1
Quick Answer
The P220E diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the NOx (nitrogen oxide) sensor heater control circuit in Bank 1 Sensor 1. Common causes include Faulty NOx Sensor: The NOx sensor itself may be damaged or malfunctioning, causing issues with the heater control circuit, Wiring Issues: Corrosion, breaks, or shorts in the wiring connected to the NOx sensor can disrupt the heater control circuit, ECM Malfunction: A problem with the engine control module can prevent the proper voltage or current from reaching the NOx sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P220E Dodge Description
The P220E diagnostic trouble code (DTC) for Dodge vehicles specifically refers to an issue with the NOx (nitrogen oxide) sensor heater control circuit in Bank 1 Sensor 1. This sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases to ensure compliance with emissions regulations. The heater control circuit is crucial for maintaining the sensor's optimal operating temperature, which is necessary for accurate readings.
Common Causes of P220E Dodge
- Faulty NOx Sensor: The NOx sensor itself may be damaged or malfunctioning, causing issues with the heater control circuit.
- Wiring Issues: Corrosion, breaks, or shorts in the wiring connected to the NOx sensor can disrupt the heater control circuit.
- ECM Malfunction: A problem with the engine control module can prevent the proper voltage or current from reaching the NOx sensor.
- Fuse Failure: A blown fuse in the heater circuit can prevent the sensor from receiving power.
- Environmental Factors: Exposure to extreme temperatures or contaminants can damage the NOx sensor and its components.
Symptoms of P220E Dodge
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning NOx sensor can lead to incorrect fuel mixture adjustments, resulting in decreased fuel efficiency.
- Rough Idle: The engine may experience rough idling or hesitation due to inaccurate sensor readings.
- Failed Emissions Test: If the NOx sensor is not functioning properly, the vehicle may fail emissions tests due to increased nitrogen oxide emissions.
- Reduced Engine Performance: The ECM relies on data from the NOx sensor to optimize engine performance, so a faulty sensor can lead to reduced engine performance.
How to Fix P220E Dodge
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the specific trouble code and confirm the issue with the NOx sensor heater control circuit.
- Inspect Wiring: Check the wiring harness connected to the NOx sensor for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test NOx Sensor: Test the NOx sensor itself to determine if it is functioning properly. Replace the sensor if it is found to be faulty.
- Check ECM: Inspect the engine control module for any signs of malfunction or damage. Reset or replace the ECM if necessary.
- Clear Codes: After completing the repairs, clear the diagnostic trouble codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P220E Dodge
The typical repair costs for addressing a P220E DTC related to the NOx sensor heater control circuit range from $200 to $500, including parts and labor. However, it's important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. For a more accurate estimate, it's recommended to inquire about local rates before proceeding with the repair.

Frequently Asked Questions about P220E Dodge Code
1. What does the OBDII code P220E mean on a Dodge?
P220E indicates an issue with the NOx sensor heater control circuit for Bank 1, Sensor 1, specifically a range or performance problem.
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.
